GSM & GPRS

What are GSM and GPRS?

by

The European Telecommunications Standards Institute (ETSI) has developed GPRS technology to make data across the GSM network, fast and more attractive. This is still a technology under development and most of the UK operators are planning to upgrade their networks. GPRS can be much faster than other traffic on GSM but the exact speed a single user sees will be directly related to the total number of users in a particular cell. However most GPRS transactions will be short hence reducing any delays. GPRS is designed for the internet hence internet services such as File Transfer Protocol (FTP), Web browsing, Internet chat will be possible at very fast speeds. It will also be an ideal mechanism for WAP. The operators will benefit from new revenue generating streams requiring short exchanges of information like telematic type applications such as automatic tollbooths. Other uses can be to check your bank balance or to initiate a fund transfer to pay bills. The potential for GPRS is immense and is considered to be a step towards UMTS the next generation of mobile technology.

Second Generation Mobiles (GSM)

GSM is currently being used by all four UK operators to provide their national mobile service. This is also known as 2G in the industry. The services include voice, e-mail, SMS. The level of coverage varies from region to region hence it is important to check whether you have coverage in your area prior to purchasing. WAP is a feature that enables mobile access to the Internet but this service has not been successful due to its capacity limitations. There is a GPRS service currently being offered by some of the operators and this is known as 2.5G in the industry. GPRS is geared towards offering better data services and is a migration step to third generation mobiles.
