most, and each sector could provide 70M independent bandwidth, and the covering range of each base station is 10 times as much as 3G base station. Therefore, somebody thought that WiMAX would take the place of 3G and become the next mainstream technology in communication field.
And based on this, WiMAXzz developed 802.16a, whose work band is lower than 802.16. It mainly works at the band range 2-10 G, so the ability that signal could get around obstacle has been improved greatly. So far it could already support non-line-of-sight transmission, which means that there could be trees or constructions blocking between the base station and client. WiMAX applied filed had been widened.

As for the problem that 802.16a has no movability performance, WiMAX established 802.16e criterion based on this. And according to the 802.16e criterion, handheld PDA or mobile computing devices would not interrupt if using wireless connection. Therefore, WiMAX got the movability ability.
From these views, we can conclude that WiMAX is a wireless network technology having a wider application than WiFI. So far, it seems there’s no power could stop the popularity of WiMAX, the only suspense is that what to do with WiMAX.

WiMAX is revolution sprit is on its cheapness but nothing else. You know that god won’t refuse it neither.
