A new whitepaper released by Intel asserts that WiMAX technology is more spectrally efficient than other mobile data technologies, resulting in advantages for operators including more subscribers per cell site and higher QOS data rates.
While large headline-grabbing theoretical/peak data rates of 50Mbps+ continue to be batted around the industry by proponents of HSPA and LTE, the more important measure is how efficiently these technologies use scarce spectrum resources. It is widely acknowledged that mobile data traffic demand will outpace the supply of actual network data capacity in the coming years, and therefore the average realized data throughput is the real metric that should be compared.
The whitepaper highlights the importance of spectral efficiency and the basics for calculating system capacity on a wireless network. The report compares mobile WiMAX 802.16e against three other technologies - HSPA (Rel 6), HSPA+ (Rel 7) and LTE (Rel 8).
According to the report, WiMAX is able to support a higher number of subscribers per cell site compared to the other technologies while supporting high QoS data rate applications. For example, using a 10MHz channel, WiMAX is able to support 20 video streaming users per sector at 256 kbps, compared to 12 users at 128 kbps on an HSPA network. Furthermore, WiMAX networks are able to support a large number of users even with high monthly data usage of 12GB per subscriber.
