Thanks for your interest. These detailed questions suggest you know much more than a neophyte would. 1) Wi-LAN's implementation of OFDM, W-OFDM, with Reed Solomon forward error correction, is a spread spectrum technique. I do not know what a refinement in this context would mean. It is better than other techniques since it has better utilization of the spectrum. This efficient utilization of spectrum makes generic OFDM susceptible to interferers. However, there are many refinements that improve this. For outdoor applications such as those in wide area networks that Wi-LAN is targeting, there is no worry of microwave ovens. For indoor use, 2.4GHz could be used but the 5.2GHz band is more appropriate. 2) Wi-LAN's target market is point to multipoint public data networks. Wi-LAN's I.WiLL product is designed for this market. OFDM can definitely be used to augment (complement) other cellular technologies. 3)The only factor working against OFDM today is that it is a new technology that is growing. Wi-LAN is betting that eventually, W-OFDM could make it into every high-speed communications device. Hatim
