Radio design considerations for EDGE handsets

摘要

The cellular handset is evolving into a data-oriented device. Data-oriented applications including digital photography and video, mobile gaming, and mobile commerce are becoming increasing mainstream. Handset features that were once reserved for high-end handsets only, such as colour screens, digital cameras, and stereo sound, and now becoming standard features on mid-range handsets. To support increasing amounts of data traffic, network operators are implementing new high-speed data technologies such as EDGE (Enhanced Data-rates for GSM Evolution) onto the GSM network.
