Evolution of Mobile Base Station Architectures

Abstract With the proliferation of wireless standards such as GSM/EGPRS, WLAN, WiMAX, WCDMA, HSDPA/HSUPA, and WiBRO — future wireless radio base stations will need to support multiple air-interfaces, frequency bands and modulation formats. Radio technology that enables reconfigurable hardware across multiple standards is a big challenge for base station developers. In this paper base station architecture evolution towards full software defined radio technologies is analyzed.
