Throughput coverage simulations based on signal level measurements at 825 MHz and 3535 MHz

This contribution compares the predicted downlink throughput coverage of a WiMAX-like system - located in a rural environment - for different operating frequencies and transmit power levels. The throughput, which is simulated using the parameters of the IEEE 802.16e-2005 standard, is based on extensive received signal power level measurements carried out with a mobile radio scanner at the frequencies 825 MHz and 3.5 GHz. The resulting path losses are combined with a virtual transmitter-receiver system to compare the throughput coverage at different frequencies and transmit power levels for each location. The outcome of the throughput prediction clearly shows that in built-up areas the use of lower frequencies is beneficial in terms of both needed transmit power and achievable coverage to provide high data rates over the air.
