Lin Sun is a Beijing-based consultant with more than 20 years’ experience with the Chinese telecom industry. Recently he has analysed the future of WiMAX in the backdrop of 3G in an atricle. Excerpts are stated bellow:
If speed is compromised, cost will become a serious concern. According to estimates, operator capex for WiMAX will be 20 percent to 50 percent higher than for HSDPA, a software-enabled overlay for sending data over 3G networks. At higher frequency, say 3.5 GHz, the number of WiMAX base stations must increase, as many as 50 percent more than for HSDPA, to cover the same area without signal degradation. This is the last thing Chinese operators want after already plunking down billions on 3G networks.
