шо такое GmPRS ?
Since the protocol architecture of GMR-1 is heavily based on GSM, enhancements to the GSM protocol can be incorporated into GMR-1. The most important evolutionary step of GSM is the inclusion of packet switched services via the GPRS and EGPRS protocol. GMR-1 has already begun this evolutionary process. The system design supports data rates up to 144 kbps for early service (BGAN-R) and 432 kbps with planned future enhancements. The initial phase of Geo-mobile packet radio service (GMPRS) will accommodate features of EGPRS such as extended modulation and coding scheme code points. The following figure shows the evolution path of GMR-1 from GSM to satellite, and then on to GPRS.

так вот а русским понятным языком - что это за зверь?
