PTCL is Going to Launch Pakistan's Fastest wireless Internet Name as CharJi (4G LTE)

PTCL is going to launch 4G and 3G networks in Pakistan, which will be faster than ever, the service name will be CharJi (4G). It will provide 36 Mbps internet speed which is much faster then previous. You don’t have to wait for this service for long because PTCL is going to launch it in 2 weeks. The uploading speed of this service will be 7 Mbps and it will consist on PTCL’s existing WLL technology, it will be either a WiFi device or USB like before. the rumored charges of this service is about 3000 rupees per month. PTCL is aiming to become Pakistan’s number one internet service.

Withen 2 weeks PTCL has announced to launch this service means maximum 15 days will be hard to wait for PTCL consumers to use 36Mbps speed. Upto 36Mbps download speed and 7Mbps upload speed is being offered by PTCL. Withen PTCL company its name is “Char G” and user will experience 20 Mbps of speed on their devices. We confirmed through a foreign source that the devices to use 36 Mbps speed will be like Dongle and evo devices. Hope it will be a new revolution for Pakistanis and the 4G craze will be limited after the 36Mbps launch of internet speed by PTCL.

3G and 4G Technology in Mobile Phones.

3G And 4G Diffarnce!

How much faster is 4G compared to3G and what applications run better on 4G?

3G vs 4G

3G and4G are standards for mobile communication. Standards specify how the airwaves must be used for transmitting information (voice and data). 3G(or 3rd Generation) was launched in Japan in 2001. As recently as mid-2010, the networks for most wireless carriers in the U.S. were 3G. 3G networks were a significant improvement over 2G networks, offering higher speeds for datatransfer. The improvement that 4G offers over 3G is often less pronounced. Analysts use the analogy of standard vs Hi-Def TVto describe the difference between 3G and 4G. Network Architecture: Wide Area Cell Based Integration of wireless LAN and Wide area. Services And Applications:CDMA 2000, UMTS, EDGE etcWimax2 and LTE-Advance Forward error correction (FEC): 3G uses Turbo codes for error correction. Concatenated codes are used for error corrections in 4G. Frequency Band:1.8 – 2.5GHz2 – 8GHz What is 4G? The definition of 4G has changed over the years. Current commercially available technologies LTE (Long-Term Evolution) and WiMax claimed thatthey are sufficiently advanced from 3G and thus claimed the right to call their technology 4G. However, in October 2010, the global standards group International Telecommunication Union declaredthat after long study, it had determined which technologies truly qualified for its IMT-Advancedlabel i.e.4G(fourth-generation). The target speed wasat least 100 Mbps to qualify for the 4G label. Only two systems made the list: LTE-Advanced, an emerging version of LTE technology, and Wireless MAN-Advanced, the next version of WiMax, also called WiMax 2. Neither is commercially available yet. But in December 2010, the standards body softened its stance. In a press release, the ITU stated: As the most advanced technologies currently defined for global wireless mobile broadband communications, IMT-Advanced is considered as '4G,' although it is recognized that this term, while undefined, may also be applied to the forerunners of these technologies, LTE and WiMax, andto other evolved 3G technologies providing a substantial level of improvement in performance and capabilities with respect to the initial Third Generation systems now deployed.This opened the door for LTE, WiMax and HSPA+ to be designated 4G because these technologies can all deliver multiple megabits per second upstream and downstream, far more than most existing 3G networks. 4G Speed vs. 3G How much faster is 4G compared to 3G? Unfortunately for consumers, the answer to this question is more nuanced than one would like. The speed of a 3G network depends upon how it is implemented. In the US, by 2010 Sprint and Verizon (both CDMA networks) had reached the limits of how fast they could make their 3G networks. Upgrading to 4G networks allowed them to offer data transmission speeds up to four times faster than their 3G networks. However, the 3G networks of GSM carriers AT&T and T-Mobile were designed such that there was room to upgrade 3G speeds. As of mid-2010, it is anticipated that when AT&T and T-Mobile upgrade their 3G networks, their speeds will become comparable to 4G from Sprint and Verizon.

GPRS Technical Defination and Information!

"GPRS" stands for "General Packet
Radio Service" and was the first
popular data standard for mobile
phones.
GPRS was used for WAP and MMS
messages and offered modest
connection speeds - typically
30-40 Kbit/s, although the
theoretical maximum is 115 Kbit/
s. GPRS is known as a '2.5G'
Technology.
One of the early advantages of
GPRS is that it s "Always On" so no
connection handshake is needed.
It is still very popular, especially in
the developing world.
