EDGE: A Stepping-stone Toward 3G Technologies in Pakistan

ABSTRACT

The business of wireless data is expected to grow in the region of 100-200 % per annum and the mobile communication industry agrees that wireless data services will form the foundation for future business. The enormous success of short messaging in many countries proves that people accept the benefits of non-voice services.

Enhanced Data Rate for Global Evolution (EDGE) is a technology that gives Global Systems for Mobile Communications (GSM) the capacity to handle services for the third generation of mobile telephony. It provides three times the data capacity of General packet Radio Service (GPRS). Using EDGE, operators can handle three times more subscribers than GPRS; triple their data rate per subscriber, or add extra capacity to their voice communications.

This article provides an overview of EDGE technology. In particular, starting from the introduction of this 2.5G technology I describe the core technical aspects and distinct features. I will provide a comparison with GPRS for data services and then a survey of the current state of this technology in Pakistan. I have also covered some benefits for operators and customers.

1. Introduction

The importance of wireless data and multimedia services both for business and end customers are increasing on an unparalleled scale. Enhanced Data Rates for GSM Evolution (EDGE) is a new radio interface solution and is based on an enhanced modulation. EDGE offers GSM network operators an evolution path to mobile data and multimedia services with a three fold increase of data throughput in the existing GSM spectrum. EDGE therefore provides an alternative for operators who do not have a Universal Mobile Telecommunication System (UMTS) license. Moreover it also represents a complement to UMTS for operators intending to first deploy UMTS only in densely populated areas, but who can also use EDGE to provide wide area coverage of future oriented 3G services. In the US market operators have chosen EDGE as the 3G solutions. [8].

We are presently experiencing the Wireless Application Protocol (WAP) as well as the higher   transmission  speeds of High Speed Circuit Switched Data (HSCSD), joined by the convenience of “always on-line” direct Internet connections with GPRS. [1]

EDGE, new radios interface technology with enhanced modulation, increases the HSCSD and GPRS data rates by up to three fold. EDGE modulation is going to increase the data throughput provided by the packet switched service even over 400 kbps per carrier. Similarly, the data rates of circuit switched data can be increased, or existing data rates can be achieved using fewer timeslots, saving capacity. Accordingly, these higher speed data services are referred to as EGPRS (Enhanced GPRS) and ECSD (Enhanced Circuit Switched Data).

EDGE, is a major improvement in GSM phase 2+. As a modification to existing GSM networks, EDGE does not require new network elements. [1]

In the US, for instance, EDGE is part of the IS-136 High Speed concept, which is one of the third generation Radio  Transmission  Technology (RTT) proposals from TR.45. EDGE is eventually going to be standardized which makes possible to achieve a global mobile radio system with many services characteristic to third generation systems.

2. Overview

The increased bit rates of EDGE put requirements on the GSM/GPRS network architecture. Figure. 1 illustrates the GSM/GPRS architecture, the shaded parts of which are discussed in this section. Other nodes and interfaces are not affected at all by EDGE introduction. An apparent bottleneck is the A-bis interface, which today supports up to 16 kb/s per traffic channel. With EDGE, the bit rate per traffic channel will approach 64 kb/s, which makes allocation of multiple A-bis slots to one traffic channel necessary. Alternative asynchronous transfer mode (ATM) or IP-based solutions to this problem can also be discusses.

One important fact is, however, that the 16 kb/s limit will be exceeded already by the introduction of two coding schemes (CS3 and CS4) in GPRS, which have a maximal bit rate per traffic channel of 22.8 kb/s. Consequently, the A-bis limitation problem is being solved outside the EDGE standardization, and it is therefore a GPRS related, not EDGE-related, modification. For GPRS-based packet data services, other nodes and interfaces are already capable of handling higher bit rates, and are thus not affected. For circuit-switched services, the A interface can handle 64 kb/s per user, which is not exceeded by EDGE circuit-switched bearers. [9]

2.1. Impact on GSM Network Planning

An important prerequisite, which to a large extent will determine the success of EDGE in GSM, is that a network operator be able to introduce EDGE gradually. For initial deployment, EDGE-capable transceivers will supplement standard GSM/GPRS transceivers in a subset of the existing cells where EDGE coverage is desired. Hence, an integrated mix of GSM, GPRS, and EDGE users will coexist in the same frequency band. To minimize effort and cost for the network operator, radio network planning (including cell planning, frequency setting of power and other cell parameters) must not require extensive modification.

2.1.1. Coverage Planning

One characteristic of non-transparent radio link protocols that include automatic repeat request (ARQ), is that low radio link quality only results in a lower bit rate for the user. Hence, low SIR for a user does not result in a dropped call, as for speech, but in a temporary decrease of user bit rate. For transparent bearers, which typically offer a constant bit rate, link quality control must be extended to incorporate resource allocation, in the sense that the number of dynamically allocated time slots fits the bit rate and bit error rate (BER) retirements. Transparent bearers, will thus be available in the entire GSM cell, but require fewer time slots in the center of the cell (where 8-PSK coding schemes can be used).

2.1.2. Frequency Planning

Most mature GSM networks of today have an average frequency reuse factor of around 9 (meaning that available frequencies are divided into nine frequency groups). However, there is also a trend toward tighter reuse factors. With the use of frequency hopping, multiple reuse patterns (MRP), and discontinuous  transmission  (DTX), reuse factors as low as 3 become feasible. EDGE supports a variety of reuse patterns. In fact, by its use of link quality control, EDGE can be introduced in an arbitrary frequency plan, and benefit from high SIR closer to the base stations. EDGE can be introduced in an existing GSM frequency plan, and that it also supports future high-capacity solutions based on tighter frequency reuse.

2.1.3. Radio Network Planning

An important prerequisite (and to a large extent, one that will determine the success of Edge) is that network operators should be able to introduce Edge gradually. The initial deployment of Edge-capable transceivers will supplement standard GSM transceivers in a subset of cells where Edge coverage is desired. An integrated mixture of circuit-switched, GPRS and Edge users will thus coexist in the same frequency band. To minimize operator efforts and costs, Edge-related implementation must not require extensive modification of the radio network plan (including cell planning, frequency planning, the setting of power levels and other cell parameters).

2.1.4. Channel Management

After Edge has been introduced, a cell will typically include two types of transceiver: standard GSM transceivers and Edge transceivers. Each physical channel (time slot) in the cell can be viewed as being one of at least four channel types:

1. GSM speech and GSM circuit-switched data (CSD);

2. GPRS packet data;

3. Circuit-switched data, enhanced circuits witched data (ECSD), and GSM speech;

4. Edge packet data (EGPRS), which allows a mix of GPRS and EGPRS users simultaneously.

While standard GSM transceivers only support channel types 1 and 2, Edge transceivers support all four channel types. Physical channels are dynamically defined according to terminal capabilities and needs in the cell. For example, if several speech users are active, the number of type-1 channels is increased, at the expense of GPRS and Edge channels. Obviously, channel management must be automated, to avoid the splitting of channels into static groups. Otherwise, trunking efficiency would diminish.

3. Interleaving

To increase the performance of the higher coding schemes in EGPRS (MCS7 to MCS9) even at low C/I, the interleaving procedure has been changed within the EGPRS standard. When frequency hopping is used, the radio environment is changing on a per-burst level. Because a radio block is interleaved and transmitted over four bursts for GPRS, each burst may experience a completely different interference environment. [7]

If just one of the four bursts is not properly received, the entire radio block will not be properly decoded and will have to be retransmitted. In the case of CS4 for GPRS, hardly any error protection is used at all. With EGPRS, the standard handles the higher coding scheme differently than GPRS to combat this problem. MCS7, MCS8 and MCS9 actually transmit two radio blocks over the four bursts, and the interleaving occurs over two bursts instead of four. This reduces the number of bursts that must be retransmitted should errors occur. The likelihood of receiving two consecutive error free bursts is higher than receiving four consecutive error free bursts. This means that the higher coding schemes

for EDGE have a better robustness with regard to frequency hopping.

4. EDGE & GPRS

EDGE, or the Enhanced Data Rate for Global Evolution, is the new mantra in the Global Internet Connectivity scene. EDGE is the new name for GSM 384. The technology was named GSM 384 because of the fact that it provided Data  Transmission  at a rate of 384 Kbps. It consists of the 8 pattern time slot, and the speed could be achieved when all the 8 time slots were used. The idea behind EDGE is to obtain even higher data rates on the current 200 KHz GSM carrier, by changing the type of the modulation used.

Now, this is the most striking feature. EDGE, as being once a GSM technology, works on the existing GSM or the TDMA carriers, and enables them to many of the 3G services. Although EDGE will have a little technical impact, since its fully based on GSM or the TDMA carriers, but it might just get an EDGE over the up coming technologies, and of course, the GPRS. With EDGE, the operators and service providers can offer more wireless data application, including wireless multimedia, e-mail (Web Based), Web Infotainment, and above all, the technology of Video Conferencing.

Now all these technologies that were named earlier, were the clauses of the IMT-UMTS 3G Package. But, with EDGE, we can get all these 3G services on our existing GSM phones, which might just prove to be a boon to the user.

The current scenario clearly states that EDGE will definitely score higher than GPRS. The former allows its users to increase the data speed and throughput capacity, to around 3-4 times higher than GPRS.

Secondly, it allows the existing GSM or the TDMA carriers to give the sophisticated 3G services. And with 1600 Million subscribers of GSM in over 170 countries, offer the full Global Roaming, anywhere between India to Japan and to San Francisco. Based on an 8 PSK modulation, it allows higher bit rate across the air Interface. There is one symbol for every 3 bits. Thus, EDGE Rate is equal to 3x GPRS Rate.

5. Future Evolution Towards WCDMA

The next evolutionary step for the GSM/EDGE cellular system includes enhancements of service provisioning for the packet-switched domain with the service provisioning in UMTS/UTRAN (UMTS terrestrial radio access network). GERAN will provide improved support for all quality of service (QoS) classes defined for UMTS: interactive, background, streaming and conversational. By doing so, a new range of applications, including IP multimedia applications, will be adequately supported. This part of the GSM/EDGE evolution focuses on support for the conversational and streaming service classes, because adequate support for interactive and background services already exists. Additionally, parallel simultaneous bearers will support multimedia applications with different QoS characteristics towards the same MS, such as multiple media streams handled through IMS domain. A driver for such evolution on the packet-switched side is the paradigm shift within the telecommunications world from circuit to packet-switched communications.

Both the core network defined for GPRS and the current GSM/EDGE radio access network require modifications to support enhanced packet services. The GPRS/EGPRS networks can quickly and cost effectively evolve with market needs, and align with services provided by WCDMA networks. The current evolution of GSM/EDGE, which covers all of the above aspects, is being standardized in 3GPP TSG GERAN. [4]

6. EDGE in Pakistan

Pakistan has the sixth largest population in the world – approximately 150 million. There are currently four mobile operators in the country. Mobile penetration at the end of 2003 was just 2.3% with a subscriber base of 3.4 million, while fixed line penetration was approximately 2.4%. Many geographic areas in Pakistan are without telephone coverage. To accompany recent positive economic development in Pakistan and the inherently low mobile penetration, high growth within the mobile segment is expected. At the moment the people in Pakistan are more concern with the text-enabled facility like SMS. Although the introduction of GPRS gave a new concept and new boost in Cellular network but still, people are not that much concern using Internet by their terminal. Few think that it still more costly and few believe that GPRS didn’t develop the interest for using Internet if we compared it by computer.

In April 2004 Norwegian mobile telecom operator, Telenor, bid for and ultimately won a license to operate a cellular network in Pakistan. The license covers the operation of Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS) and Enhanced Data Rates for Global Evolution (EDGE) technology for the network. [14]

Telenor Pakistan has signed two deals with mobile infrastructure contractors for different areas of the network:

Nokia have signed a three-year deal to build and operate a GSM / GPRS / EDGE network to cover the central and Northern Punjab region (phase one), centered around Lahore.

Siemens have signed a deal to build a GSM / GPRS / EDGE network to cover the southern areas of Pakistan, centered around Islamabad.

Further enhancements in data capability over the core GPRS / GSM network will be provided in both networks with the installation of Enhanced Data for Global (GSM) Evolution technology. This component of the two systems will be installed after the initial roll-outs and will allow the subscribers to have the use of advanced mobile services such as downloading video and music clips, full multimedia messaging, high-speed color Internet access and email on the move.

Nortel Networks will upgrade Ufone’s existing wireless systems and supply new GSM/GPRS core network and radio access equipment, including Mobile Switching Center, Home Location Register (HLR) and advanced Base Transceiver Stations (BTS).

A key component of the Ufone expansion will be Nortel Networks BTS 12000, designed to deliver additional capacity within a GSM/GPRS network while positioning operators to drive lower costs and to offer advanced wireless services based on third generation (3G) EDGE (Enhanced Data for GSM Evolution) technology. The expansion will also include Nortel Networks Passport Packet Voice Gateway (PVG) for migration of TDM voice trunking to a packet-based infrastructure.

7. Benefits

As highlighted previously the need to reduce business risk and make the best use of existing resources is of paramount importance within today’s business environment.

7.1. Financial

GSM based networks have become the standard within the cellular landscape. As EDGE is a GSM based technology and provides an enhancement for GPRS at a little additional cost it is considered the best way in which to capitalize on existing resources. [1]

7.1.1. Radio Access Network

In most cases GPRS enabled base stations and BSC’s can be simply upgraded to EDGE by way of relatively low-cost software and hardware upgrades, which will pro-long the life cycle of the deployed RAN elements.

7.1.2. Core Network

For GPRS enhancement, there is very little modification to be completed within a GPRS enabled core network, thus enhancing the sunk core network investment.

7.1.3. Antenna Sites

There is no requirement for additional antenna sites when deploying EDGE. Assuming high quality linear amplifiers with high RF output power are used within the BTS, the coverage pattern will be the same as the existing GPRS deployment, so protecting existing site investment.

7.1.4. Spectrum Utilization

EDGE triples the GPRS data capacity whilst using the existing GSM spectrum and offers up to three times the GPRS data rate to the end user. EDGE is spectrally the most efficient radio technology for data applications requiring up to 100Kb/s throughput (compared to CDMA and WCDMA), and only WCDMA is spectrally better for higher throughputs.

7.1.5. Applications

GPRS enabled applications and services will generally not require any additional investment to become EDGE compatible. This is also valid for known WCDMA applications.

Although the financial benefits of EDGE can be apportioned to individual network elements as outlined above, one of the main business drivers is that EDGE forms an essential part of the overall GSM evolution towards a seamless multi-radio GSM/ GPRS/EDGE/WCDMA network. As mentioned previously GSM is the main standard for cellular communications worldwide and the business benefits of deploying an industry standard technology can be seen in nearly every aspect of a network deployment, from end-user devices, to applications to hardware.

7.2. For Operator

Operators can also experiences the advantages of EDGE in following ways.

7.2.1. Migration to wireless multimedia services

The operator can increase data revenues by offering attractive new types applications to end-users.

7.2.2. Improved customer satisfaction

Increased data capacity and higher data throughput will decrease response times for all data services, thus keeping end users satisfied and connected.

7.2.3. Early deployment of 3G type applications

EDGE networks are expected to emerge in year 2001, when mature markets are likely to start demanding multimedia applications.

7.2.4. Quick network implementation

EDGE will not require new network elements and EDGE capability can be introduced gradually to the network.

7.3. For User

7.3.1. Improved quality of service

Increased data capacity and higher data throughput will eventually satisfy the customers’ need for QoS.

7.3.2. Personal multimedia services

Attractive new types of applications and terminals will become available.

7.3.3. Potentially lower price per bit

Lower cost of data capacity for high-speed data applications gives the operator flexibility in pricing.

8. Conclusion

While the tug of war between access technologies – CDMA vs. UMTS vs. GSM — continues to be debated globally, EDGE provides an ideal solution for GSM carriers to add data capacity using limited spectrum. Keeping in view the fact that GSM supports more subscribers today than any other access technology (roughly 65 to 70% of the global subscriber market), and that GSM/GPRS operators are scrambling to add capacity to support user growth and launch next generation data services, the increased capacity and throughput offered by EDGE becomes very compelling. And, in a market where wireless carriers must squeeze the most out of capital outlays–past and future, it is no real surprise that we are going to see a renewed wave of interest in EDGE from our GSM customers.

Today the position of EDGE as a technology evolution of GSM is clear. Initially promoted as an alternative to WCDMA and generally a niche technology, EDGE is now regarded as a key enabler for GSM/EDGE and WCDMA operators alike. Being able to drive business value from existing GSM infrastructure and spectrum is one of the main advantages, and along-with the ability of EDGE to reduce CAPEX, time-to-market and time-to-revenue, with regards the delivery of global high-speed data services, EDGE is a must technology.

The cellular companies working in Pakistan did not have the license for the EDGE. Now as the introduction of some new companies like Telenor and WARID, it is possible that in near future Pakistan will also be able to use this facility. Then GPRS can become a real important factor in cellular network, as the people in Pakistan will use the Internet not only for downloading ring tones but also can enjoy the streaming videos by their cell phone and so many other facilities.

The Avian Plight

In 1997, the world’s attention was caught by an alarming passage of Avian influenza from birds to humans in Hongkong. All chickens and ducks were killed upon the order of the Hongkong government to contain the spread of the deadly H5N1 virus.

Avian influenza or more commonly called as bird flu is an infection caused by avian (bird) influenza (flu) viruses. All birds naturally have these influenza viruses in their bodies. Wild birds have these viruses in their intestines but their bodies do not get infected or damaged by them. When passed on domesticated birds, avian influenza can cause sickness and death. Chickens, ducks, and turkeys are mostly hit by the   transmission  of avian flu among birds. Infected domesticated birds can pass on the virus to humans when they are eaten or consumed. *Migratory birds* infected with avian flu also become agents of viruses’ transfer from one place to another.

H5N1 carrier birds pass on the virus to other birds through their saliva, nasal excretions, and feces. Birds get infected when they come in contact with these contaminated excretions even by just staying on a surface or ground where virus carriers have stayed. Cages, dirts, water, feeds, infected waterfowl or other poultries that have been exposed to the virus are the common sources of infection among domesticated birds.

Two forms of bird flu exist among domesticated poultries infected with avian influenza viruses. The low pathogenic form is almost invisible and undetected for it causes only very mild symptoms that can be mistaken as non-avian flu effects. Manifestations of low pathogenic avian flu infection include low egg production or ruffled feathers. The second form of avian flu is the high pathogenic avian flu disease. This form leads to multiple organ failures and damages among infected birds. About 90 to 100 percent of birds infected with this form die within two days upon contamination. The spread of this form of avian flu is more rapid among birds in flocks.

Albeit basically a matter among birds, humans are also susceptible to bird flu or avian flu infection. The first known cases of humans getting infected with bird flu happened in Hongkong in 1997. 18 people were recorded to have acquired respiratory illnesses after having contacted infected surfaces from poultry farms, the infection claimed six lives.

The virus’ passage to humans that happened in Hongkong caused a global alarm. Health institutions worldwide raised concerns that the avian flu might be as damaging as the pandemic of flu that claimed about 20 million lives back in 1918. Reasonable enough, the fear and alarm are worth noting. What is essentially fearful is the idea that humans can be infected and actually die from a virus that is basically existing among birds only. The premise the Hongkong incident set is that the virus is mutating into something deadly for humans.

As of 2005, worldwide coordinated statistics recorded a number of 130 people having been infected of avian flu of which 67 have already died. In recent years, cases of human infection have been high in Asian countries. The World Health Organization believes that Asia is at higher risks since people live in close distance with domesticated birds like chicken and ducks. Animal domestication and poultry raising are common among many Asian countries who are agricultural by nature. What worries many is the common fact that humans have little or even a lack of immunity to the virus known to be infecting only (until the 1997 Hongkong incident) the birds.

An even higher cause of alarm has been found in recent studies on the H5N1 virus. Recent researches have shown that H5N1 strains have become more deadly among chickens and mice. This mutation is also found to be making cats or feline susceptible to the infection. H5N1 is also found to be resistant to some of the drugs used to treat flu (such as amantadine). New strains of the virus are also said to be possibly emerging especially in Asian countries.

What is now being focused on by scientists and health experts around the world is the prevention of human-to-human  transmission  which is believed to be the possible case that happened in Thailand in 2004. If it becomes widespread, human-to-human  transmission  is believed to be harder to contain that bird-to-human  transmission . Experts say that the virus’ continual change will make it hard for the human body to naturally develop immunity against the infection. The H5N1 virus is found to be changing over time through the changes happening in their structure called antigenic drift and antigenic shift. This continual change of the virus disables the immune system to respond accordingly whenever the flu virus enters the body. The only possible solution seen by experts is for infection-prone people to have a yearly immunization with up-to-date anti avian virus strains. But the big problem is, until now there is no medical treatment available to combat the H5N1 virus, making the yearly immunization update a far-fetched option.

Online Dating Should Be an Olympic Sport

The Olympic Games program consists of 26 sports, 30 disciplines and nearly 300 events. It is a global event with monumental interest and cultural significance in our world. As such, I would like to formally submit Online Dating/Dating to the International Olympic Committee for consideration of inclusion as an Olympic sport for the 2012 or 2016 games.

Think this is just another boneheaded idea from your friends in the online dating world? Consider this:

Olympic sports are governed by International Sports Federations (IFs) who are in turn recognised by the International Olympic Committee (IOC) as the global supervisors of their respective sports. In layman terms, that means the big dog IOC lets the little dog IFs manage everything on a local level. Well, such a little dog already exists in the online dating world in the form of reputable online dating websites. That is right, there are some reputable dating websites that are good enough to be called established “Federations.” These websites can be the global governing body of online dating! That was the first step. Now to convince the IOC that online dating is a sport.

In terms of Olympic competition, think about it we could classify the online dating world into men, and women, then break it down further into specific weight classes, or even personality types within those weight classes. These men and women would then compete with one another physically (through flirting), intellectually (through questioning) and visually (physical appearance). It is the perfect blend of a sport. The winning Gold medalist will have to spend years in the gym training to be physically sound, spend years in school or the library “learning” to become smart, and behind all the muscles and misogynistic intellect, still be graceful in delivery and presence. The winner of the online dating would be perfect athlete, the Opus Olympian.

Not convinced it would work? Maybe your mind will change after reading this:

In October 2004, the IOC established an Olympic Programme Commission who’s job was to review all existing sports, and other non-recognised Olympic sports. In this review the goal was to apply a systematic and category approach to each sport and evaluate whether or not it met the criteria for inclusion in the Olympic games as a recognised Olympic sport. This Commission came up with seven criteria to judge whether a sport should be included or not.

1) History and tradition of the Sport

2) Universality

3) Popularity of the sport

4) Image

5) Athletes’ health

6) Development of the International Federation that governs the sport

7) Costs associated of hosting/playing the sport

The above seven criteria my friends is what a sport or discipline has to meet in order to be considered for inclusion at the Olympic Games. Period.

Does Online dating meet these 7 criteria? Lets find out:

1) History and Tradition – Check! Dating is the oldest tradition on the planet that was around before any of today’s current Olympic sports.

2) Universality – Check! I’m pretty sure dating and the sport of interpersonal communication and sparing has universal appeal. I mean, we do it every day!

3) Popularity of the sport – Check! I’d say Dating was pretty popular. Wouldn’t you? Everybody does it. Even animals. I don’t see penguins playing Soccer or Baseball, but I do see them date.

4) Image – Check! Dating is all about attraction and reflecting a positive and beautiful self image. Those who partake in the sport of dating exude the highest standard of image compared to any sport image or sport athlete! Who likes to date an unbathed, rude, and dirty human being? Puhleeze.

5) Athletes Health – Check! Dating athletes date, and date often. As such, they take their own personal health very seriously. Education about Sexually Transmitted Disease start at a young age, and practicing safe sex to maintain good sexual health is part of the every day routine for those who date.

6) Development for International Federation that governs the sport: Check! The International Federation for Online Dating, a reputable dating website, would very much benefit from online dating being included in the Olympic games.

7) Low cost of holding the sport: Check! How much does it cost to look at the person next to you and start a conversation?

In conclusion, Online Dating meets all the criteria for inclusion as an Olympic sport, in many ways better than existing Olympic sports. Consider Curling – Who is that helping? How about Fencing? Serious people… how on earth is swatting somebody with a piece of wire going to benefit people or project a good self image? Give me a break.

So without further adieu, I would like to formally submit online dating to the International Olympic Committee for consideration and recognition as a recognised Olympic Sport in the year 2012 or 2016…or even 2020. I’m not picky.

Thank you very much.

Google Redirect Virus Fix – How to Get Rid of Google Virus

Infecting users via internet exposure and nooks and crannies found in unsecured browsers are the main causes of the redirect virus. So where does one inject the use of Google redirect virus fix? In order to properly employ its use first it is essential to understand what this threat is and what it does. The redirect malware lives up to its name, the infection causes a hijacking of any search or website visit a user plans to make. Instead of finding their site of choice the virus redirects them to fake websites containing ads and even corrupted pages.

The following fake errors are displayed by the vius

  • Internet explorer cannot open web page
  • filename.exe is not a valid win32 application
  • Setup files are corrupted Please obtain new copy of program

Being a browser hijacking utility it manages to infect browsers like IE and Firefox and then redirects internet users to the following malicious sites.

  • clearask.com
  • brittaniasearch.com
  • go.Google.com
  • web-analytics.Google.com

The redirect threat is capable of disabling activated firewalls and security software which can then lead to a remotely accessible system. This allows hackers to have access over personal information such as login names, passwords, financial records etc.

What are the symptoms to consider when one wants to implement a Google redirect virus fix?

· An unknown change of desktop background

· Changes homepage

· Browsers such as IE and Firefox slows down noticeably

· Corruption of registry files thus resulting to the dreaded “Blue Screen of Death”

· Contamination of messengers, freeware and email attachments are also sure signs.

How does Google redirect virus fix work?

1. Select Show Hidden Devices under Hardware Device Manager in your Windows Control Panel.

2. Search for “TDSSserv.sys” right click Disable. Do not select Uninstall otherwise the infection will reappear once the computer is restarted.

3. Reboot the pc.

4. Immediately update antivirus software and the Google redirect virus will cease to exist in your workstation.

It pays to be vigilant and alert when using the internet. Avoid malicious sites and constantly scan your system and update your security tool to avoid contaminations. It is also best not to rely on one antivirus software alone having another reliable application can help sift through the threats that the other was incapable of detecting.

Key Facts About Bird Flu

Bird flu was first identified in the early 1900’s and has since spread worldwide. Also known as avian influenza, this virus has caused considerable concern due to the mutation of a particular strain of the disease. Although this virus previously only infected birds and other types of animals, namely pigs, since 1997, it has also been known to infect humans.

The strain of the disease to cause so much concern is H5N1. These are simply numbers and letters that represent the subtype of this particular strain, 1 of 144 influenza subtypes. Not only has the virus caused an epidemic in poultry, but it has recently been feared to be leading to a pandemic, or worldwide epidemic, in humans.

While the virus was first identified in humans in 1997, it was not until 2004 that the spread became of great concern. At that time, a major outbreak occurred in Vietnam and Thailand, which spread to ten countries and regions of Asia within weeks and caused the death of 23 people. Within three months the outbreak was contained after the slaughter of tens of millions of potentially infected birds. However, the damage was already done and the virus had spread across Asia to lead to additional outbreaks. Since that time, H5N1 has spread throughout Asia, Europe, and the Middle East, and a low pathogenic form of the virus was identified in Canada on November 19, 2005. Currently, 131 humans have been infected with the virus, resulting in 68 deaths. However, it is feared this number will only increase with the ongoing spread of the disease.

The primary concern surrounding H5N1 is its mutation and ability to infect humans. As of yet, the virus has been spread from poultry to humans, and human to human transmission has only been suspected but not confirmed. Once the virus mutates further, it will easily be passed through humans, causing the disease to spread rapidly. Influenza pandemics, or worldwide epidemics, have caused a great number of deaths in the past, including the Spanish Flu which killed 50 million people in 1918. This is the ultimate concern with the mutation and spread of H5N1.

At this time, the primary cause of infection has been due to the consumption or handling of diseased poultry. Unfortunately, there have been a very few cases that were not easily explained, and therefore, human to human transmission was suspected. However, this has not been confirmed in any of the cases of H5N1 infection.

Different Forms of Candida and How it Effects Erectile Function?

The Different Forms of Candida

There are 20 different forms of Candida, the most common being Candida Albicans. These microscopic organisms normally live on the surface of our body without causing any kind of infection or disease. However, under certain extraordinary circumstances, the population of these fungi grows so rapidly that they become the agents of yeast infection or Candidiasis. Thrush, diaper rash, nail-bed infection, vaginal yeast infection and pulmonary candidiasis are some diseases caused by Candida. Yeast infection is mostly prevalent in women; men generally contract oral yeast infection. Penile Candidiasis, or yeast infection that affects the erectile function is quite rare.

Under what situations does Candida start effecting erectile function?

Diabetes- Diabetic men usually have elevated sugar levels in their urine. This makes them the ideal candidates for yeast infection of penis. A large amount of sugar in the urine provides a feasible environment for Candida to grow and multiply in the penis and disrupt the erectile function.

Antibiotics- Prolonged use of antibiotic kills the bacterial flora that is typically present in the penis. In the absence of natural flora, the penis becomes susceptible to infection caused by Candida.

Low immunity- Often, conditions like chronic stress, HIV, hypothyroidism and Lyme lower the immunity of the body drastically and make the penis vulnerable to Candida attack.

Sexual transmission- Having sexual intercourse with a woman who has vaginal yeast infection increases the chances of developing penile candidiasis, which can disturb erectile function dramatically.

What are the symptoms of penile yeast infection?

Frequently, penis yeast infection doesn’t affect the erectile function. In such a case, it is very difficult to detect penile candidiasis. The general symptoms of the disease are excessive itching, particularly on the head of the penis, which can lead to irritation, soreness and redness. In severe cases, small blisters might also appear which is accompanied with a clumpy discharge that is white in color.

The bad thing about penile candidiasis is that its symptoms are very similar to that of genital herpes. As soon as you detect the symptoms, contact your physician immediately to ascertain whether erectile dysfunction is caused by penis yeast infection or genital herpes.

What are some remedies to overcome the adverse effects of Candida on erectile function?

The two drugs that are regularly used for the treatment of penis candidiasis are ketaconazole and fluconazole. These medicines produce their own set of side effects. For this reason, natural remedies should also be tried like yogurt, aloe vera, garlic paste, apple cider vinegar. These can be applied on the affected area for instant relief.

In addition to treatment, certain precautions are also necessary. For instance, if you or your partner is nursing a yeast infection of genital organs, it is advisable to practice safe sex. Furthermore, avoid wearing clothes that are tight at your crotch and keep your genital area absolutely clean and moisture free. Besides these, make requisite dietary changes like start taking pro biotic supplements and Vitamin C in your daily diet.

Efficiency of Candida diet against Candida that causes erectile dysfunction

Candida diet can also prove to be quite effective. While following a Candida diet, you have to avoid eating foods that are rich in carbohydrates. Chicken, meat, non-starchy vegetables, shell-fish, and nuts are found to be very helpful in the treatment of a penis yeast infection. Likewise, you should also avoid foods that are a rich source of yeast like bread, mushroom, cheese, tomato paste, vinegar, and so on.

Concluding words

Penis candidiasis is absolutely treatable. Seek medical advice at the onset of the disease, follow the instructions carefully and try to adopt a healthy and hygienic lifestyle. Switch over to a Candida diet and apart from tried and tested medication, try out natural remedies too. Moreover, keep away from all kinds of stresses and tensions. Practice yoga, meditation and other stress management techniques to overcome all the strains and stresses of your life.

Interesting Facts about Ringworm

In spite of its popular name, the actual cause of ringworm is infection with fungal organisms. These infectious fungal organisms are called dermatophytes and the medical term for ringworm is dermatophytosis. Sometimes ringworm is also known as tinea. The fungal infectious organisms responsible for causing ringworm are widespread in nature and they commonly populate the soil. The only effective means of preventing the occurrence of ringworm is to maintain a good hygiene. Ringworm is very contagious and it can easily be acquired through direct contact with contaminated people, animals or objects. Regularly wash your hands after entering in contact with stray animals, as many of them are carriers of the fungi responsible for causing ringworms in humans.

Arthrospores are the main cause of ringworm in humans. Although there are lots of animals contaminated with arthrospores, they usually don’t show any signs of the disease. For some reason, most animals appear to be immune to this form of fungal infection. Microsporum canis is a type of fungi that commonly infects cats. This type of fungus can be easily transmitted to other animals and to humans. It is strongly recommended to avoid physical contact with animals that show signs of disease in order to prevent contamination with infectious fungal elements. Also, if you own a dog or a cat, ensure that your pet is not contaminated with dermatophytes by paying regular visits to a veterinary.

Ringworm can affect virtually any region of the body. Hands and feet are very exposed to fungal infection and dermatophytes often infect these body parts. Although it commonly affects skin, ringworm can also affect nails and scalp. Ringworm involves inflammation, rash and swelling of the skin, scalp, soft tissue and nails. Rash is usually the first sign that indicates the presence of fungal infections. Skin lesions may also appear in later stages of the disease. If the infection spreads through the deeper layers of the skin it can cause pustules and painful nodules. A hardened crust often forms on the surface of the affected skin. Common symptoms of ringworm are persistent itching, soreness and irritation.

Ringworm of the scalp appears in the form of pustules or pus-filled reddish bumps. Foot ringworm usually affects the skin regions between the toes. Foot ringworm appears in the form of cracked, hardened skin. The affected skin also tends to exfoliate, causing itching and soreness. Ringworm of the nails is manifested by thickening and discoloration of the nails.

It is very important to see a dermatologist if you have the symptoms of ringworm. Although it may resemble a simple rash or irritation, ringworm can cause serious complications if it is not appropriately treated. The treatment for ringworm can be prescribed in the form of oral tablets or creams and ointments for external use. The medications used in the treatment for ringworm contain antifungal material and they are usually very effective in overcoming the infection. With appropriate medical treatment, ringworm can be completely cured within a week.

Online Education – Do You Want To Return To School?

In our rapidly changing global world, millions of students are currently taking college-level online (distance education) classes. Private and public universities in the United States and abroad are offering Certificate, Baccalaureate, Masters and Doctoral degree programs over the Internet to adult learners. From Ivy League to Community Colleges, an increasing number of students can log on to their classes from home, work or while commuting by bus and train. Adult learners frequently juggle a myriad of responsibilities including raising children, career, and care giving for senior parents. Formerly, a university of interest may have been out of reach geographically. Presently, an employee located in the United States can register for classes taught half way around the world. Non-traditional venues outside of the more traditional classroom offer viable opportunities for continuing one’s education.

Adult learners make up the largest demographic of post-secondary institutions in the United States. For this student group, the benefits of online academic programs are:

o To update current skill sets

o To learn new skill sets

o To earn an undergraduate or graduate level degree

o The fulfillment of academic requirements necessary for a current job or promotion

o To change careers

o The satisfaction of certification or licensure requirements

o Personal and spiritual growth and development

Not for the faint of heart, success in distance education academic programs requires high levels of stamina, discipline, and motivation. A good candidate must be computer literate, possess the ability to read massive amounts of material in short-time frames, have good writing and communication skills, hold high expectations for good grades, enjoy applying critical thinking and commit a minimum of 15 hours per week per course (be prepared to allocate more, if necessary).

The Internet and the World Wide Web provide the critical technology platform for distance education. University technological and operational infrastructures (including hardware, software and transmission) provide the additional cornerstones to the technology platform needed to execute distance education programs. The delivery of academic content may be accomplished in several formats. The more traditional venues are correspondence courses, videos, audio-cassettes, CD-ROMS, and broadcasts via television and radio. Modern formats include synchronous and/or asynchronous education content distribution channels. Synchronous delivery refers to real-time interaction between instructor and student i.e., two-way video-conferences, whiteboards, chat rooms, telephone software (ex. Skype), and mobile technology devices. Asynchronous interaction does not involve real time communication. Instead, interaction between instructor and student is accomplished through the use of e-mail, DVDs, and the traditional education delivery formats.

As a student, you will need a desktop or laptop computer, an Internet Service provider, a cell phone, software (i.e., word processor, financial spreadsheet, calendar and Power Point), a backup storage disk drive (nothing can make your heart drop faster than losing a body of work that you’ve diligently developed), a headset with microphone for virtual team discussions and the traditional school supplies. Optional technology may include memory upgrades, scanners, digital scanners, and fax machines.

Ten Tips For The Successful Online Student:

o Have a credit card or debit card ready for downloading e-books and other required course reading materials.

o Maintain a list of more than one bookstore in the event that a required textbook is sold out. It’s always a good idea to obtain a list of the required textbooks midway through the term and order in advance for the following term.

o Do not be shy about asking for help if needed. I cannot stress enough the importance of communicating openly with your professor or instructor about course material that you may not understand. Online academic programs tend to move rapidly and course content that you do not understand will most likely cause problems down the road resulting in frustration and possibly, lower grades.

o Seek out a tutor. If there are areas that you know need strengthening, even before the class begins, have a tutor on stand-by. Also, the telephone number of a computer specialist should be in your rolodex.

o Time management will be critical. Keep a planner. Read your syllabus as soon as it becomes available and plan accordingly.

o Uphold your responsibilities as a virtual team member. Your contributions will directly impact the team grade.

o Exercise. Long hours at the computer can cause strain on the neck, shoulder, arm and back muscles, not to mention the hands. Remember to periodically stretch and tone.

o Eat a healthy diet. Keep good healthy recipes handy. Hydrate. Avoid heavy snacking on calorie-laden food and instead eat lots of fruit and vegetables. Avoid white flour and choose high fiber grains.

o See your doctor. A healthy body feeds a healthy mind.

o Stay in contact with your Academic Advisor to be sure that you are satisfying the requirements needed to complete your degree.

In the Fall term of 2006, 3.5 million students representing 20% of all U.S. higher education students, took at least one online course (2007. The Sloan Consortium). It is projected that distance education will continue to grow in popularity domestically and internationally. The most commonly offered online academic programs are Business, Computer Science and Engineering, Education, Engineering, Library Science, Nursing, and Public Health. Whether you select a community college, public institution, private institution or Ivy League university, enjoy the learning experience.

Hemorrhoids and Anal Warts

It’s pretty bad when you find out you’ve got hemorrhoids, but it can be a lot worse if you get hemorrhoids confused with another health issue. I mean, the pain, anxiety and embarrassment of discovering something wrong in the anal area is bad enough, much less not knowing exactly what you’ve got. On the bright side, there aren’t too many health conditions that can come up in that area. One of the most common health conditions confused with hemorrhoids is anal warts. While neither is very much fun, they stem from entirely different causes and are treated in very different ways.

Anal warts, also known as condyloma acuminata, are caused by the human papilloma virus (HPV). This virus is highly contagious and most often transmitted through sexual intercourse. Some strains of HPV can lead to increased risk of cervical cancer, but these are not the same strains as the ones that cause anal warts. The virus gets into the skin or mucous tissue cells and starts making them grow in the distinctive wart pattern. HPV infection does not lead to hemorrhoids. Hemorrhoids originate from weak points in hemorrhoidal veins below the skin or mucous tissue. As the weak point gives way, it stretches out and takes surrounding tissue with it. Traumatized hemorrhoids may get infected with a variety of bacteria and/or viruses, but infection does not lead to hemorrhoids. That would be like putting the cart before the horse.

Anal warts and hemorrhoids can both feel like lumps or masses of tissue around the anal area. However, there are several differences that can lead to a proper identification upon close inspection. While doing a close inspection may not sound like fun, it’s much better than trying unsuccessfully to treat the wrong thing. Upon said close inspection, anal warts have a distinctive “rough” texture and range in size from the head of a pin to about the size of a pea and are rather hard to the touch. They occur in clusters around the anal opening and may sometimes continue up towards the genital area. They almost never occur alone. Hemorrhoids, on the other hand, have a smooth texture that’s identical to the tissue they originate from, whether that’s external skin or internal mucous membrane. They are often soft or “squishy” to the touch, and they range in size from the size of a pea to the size of a grape. You’ll never find them anywhere except right around the anal opening. In addition, warts almost never hurt, though they may itch a bit. External hemorrhoids, on the other hand, often hurt quite a lot.

Hemorrhoids are usually best treated at home through a high-fiber diet, a healthy amount of exercise, and easily obtained over the counter relief. Home remedies often work well on hemorrhoids and surgery is only rarely needed. Anal warts, on the other hand, always have to be treated surgically, usually on an outpatient basis. The warts will not go away on their own. Instead, a physician has to use liquid nitrogen to freeze them off. In addition, hemorrhoids can often be kept away by keeping the lifestyle changes that were made to help cure them. Anal warts will often come back for no reason under your control, because the virus can live dormant in your skin cells for a long time. One day that virus can wake up and bam, you’ve got anal warts again.

So, as you can see, getting anal warts confused with hemorrhoids can lead to some serious problems. At the least you’ll be stuck trying to treat a problem you don’t have for a while. Why waste all that time and discomfort? If you can’t figure out what you’ve got on your own, make a doctor’s appointment and get your diagnosis confirmed. It’ll save you a lot of trouble, pain and grief in the long run.
