Broadband wireless systems are becoming very popular today and several networks and technologies are available. The focus is here on radio resources of OFDM(A)-based air interfaces, such as WiMAX and LTE. A preliminary investigation has permitted to highlight what a 'resource' means. Then, this paper compares different analytical frameworks (for cases with and without MAC layer fragmentation), which are suitable for downlink performance evaluation in packet-switched broadband wireless systems. This study is carried out for a single traffic class, considering that b resources can be allocated on a 'frame' basis and that packets have a variable size. Simulation results have been shown to be in good agreement with theoretical results. Finally, a selected analytical method has been applied to a fixed WiMAX cell planning example (considering different IP packet lengths and the use of several modulation and coding combinations), showing the potentialities of this approach.
