Monitoring GPRS performance
Posted: 25-Feb-2001 [Source: Telecommunications Online]

[Many unique challenges facing design engineers in the transition from GSM to GPRS.]

by Richard Macquire -- "General packet radio service (GPRS) specifies a way to transfer data over the existing GSM system at rates approaching 171Kbps. Specifically, GPRS brings the following to GSM: protocol layers up to TCP/IP, multiple timeslot data transfer, packet switching, standard test modes, and new power-control schemes.

"Along with the positive aspects come some new challenges, such as higher mobile station heat, faster battery drain, and more complicated transceiver design. One potential negative impact to the much-awaited rollout of GPRS devices would be for defective mobiles to make it to the consumer, with the resulting poor operation leading to bad press.
