E-GPRS uses 200 kHz radio channels,which are the same as the current GSM channel widths.It reuses the same concepts and is based on exactly the same architecture as GPRS.The introduction of EGPRS has no impact on the GPRS core network.E-GPRS is designed to improve spectral efficiency through efficient link utilization with GMSK and 8-PSK modulation schemes,which can be alternated on the same radio slot according to radio channel conditions. With new modulation,E-GPRS increases the radio interface data throughput in average three-fold compared to GPRS.Discussed in this paper is the performance test between E-GPRS and GPRS under multiuser environments,and the optimization analysis of the E-GPRS network.
