Analyze GPRS problems using protocol tester

What is GPS?
Acronym for Global Positioning System. A series of 24 geosynchronous satellites that continuously transmit their position. Used in personal tracking, navigation and automatic vehicle location technologies. GPS was developed and is operated by the U.S. Department of Defense (U.S. DoD). Inherent errors implemented by the U.S. DoD create inaccuracies of more than 100m. Europe is building its own civilian-run positioning system, called Galileo. Its network of 30 satellites should be fully operational in 2010.

What is GPRS?
General packet radio service (GPRS) is a packet oriented mobile data service available to users of the second generation (2G) cellular communication systems global system for mobile communications (GSM), as well as in the third generation (3G) systems. In 2G systems, GPRS provides data rates of 56-114kbps.
It is often described as 2.5G—that is, a technology between 2G and 3G. It achieves its moderate-speed data transfer by using unused TDMA channels in the GSM network.
