This paper examines the rational behind EDGE and the modifications required within the network to support it. Concentrating on GSM (Global System for Mobile Communications), the principles of 8PSK (Eight Phase Shift Keying) are discussed with regards power control and planning etc. The module also examines the modifications required by GPRS (General Packet Radio Service) to support EDGE and in particular the protocols of RLC (Radio Link Control) and MAC (Medium Access Control).
The principles of convolutional coding are also examined with regards the nine modulation and coding schemes in addition to describing the significance of the EDGE families and the use of puncturing schemes.
