Software Radio Implementability of Wireless LANs
While a significant amount of work on software-defined portable terminals has been carried out, little interest has been shown on the advantages of using this technology for emerging WLAN standards. We present in this article the technical challenges raised by the design of a highly flexible, software-defined radio interface for WLAN modem. Two different design approaches are investigated, for which technological requirements, implementation complexity and power consumption have been evaluated. Performance of the required components are compared with state-of-art technology capacity and, whenever needed, evolution trends have been used to estimate their probable time of availability.
