چکیده

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.

Stretchable Architectures for Next Generation Cellular Networks

—This paper examines the technique of conserving energy in 3G cellular systems by allowing calls between a mobile and the base station to be forwarded by some other mobile in the cell. This “stretched” call has the benefit of reducing overall energy cost for the call in cases where the calling mobile is NLOS (Non Line of Sight) to the base station but is LOS to the intermediary and the intermed...
