GPRS: New Radio Interfaces
n GPRS can use various radio interfaces:
DECT, EDGE, UMTS, IEEE 802.11, IrDA (infrared)
n Radio should:
operate using packet mode
provide identifier of the downlink packets
provide reasonable residual error rates
n Wish list for radio services:
fast channel allocation and release
battery saving mechanism (sleep mode)
adaptive coding (depending on radio quality)
just one (efficient) paging channel that can be listened to also when
transferring data
