WiMAX (Worldwide Interoperability for Microwave Access) is a standards-based technology enabling the delivery of last mile wireless broadband access. It is considered as an alternative to wired broadband like cable and DSL. In the recent years, it has a rapid growth. Many professors in this filed predict that it will have a prosperous future in the global network market. |
In the WiMAX World Asia2007, Hou Ziqiang, the research professor of Institute of Acoustics, Chinese Academy of Sciences, said there would be a boom of Wimax in China in the next 5 years just like the case of Broad Band several years ago. At that time, the difference between the two only lies in the way of access technology.
Hou also pointed out Wimax was designed to serve the mobile network. "Not long ago, Microsoft and Google jointly advised the American Government to develop the Wimax at the frequency of 700Mhz". Although this proposal hasn't been ratified, Sprint Nextel has already applied Wimax at the frequency of 2.5Ghz.
For the SPservice provider of Wimax, adopting 700Mhz frequency has the superiority of excellent and stable propagation. Especially to the remote areas, it can provide wider coverage. However, the 700Mhz frequency and some related devices belong to the State Administration of Radio Film and Television. So in order to vigorously develop Wimax in China, the close cooperation between the Administration and the provider is very essential and necessary.
