WiMAX has an excellent opportunity to expand China’s market for fixed, portable, and mobile broadband access. Though traction in the 802.16-2004 (fixed) market will be important, the real success of WiMAX in China will depend on the much larger 802.16(e) market.
China is an increasingly active test bed and emerging market for new technologies. With its large population (1.3 billion), high rate of GDP growth (9% per year) and increasing mobile user base, China would appear to offer a wealth of opportunities for WiMAX. There is a common view that the Asia Pacific will be the key global market for WiMAX, with China being the core long term opportunity for WiMAX vendors and service providers. It is therefore no wonder that the WiMAX Forum regards China as a key strategic region for growth.
And at the same time, some Chinese Telecom vendors such as ZTE and Huawei have put a lot of effort in developing WiMAX products. What they focus on is not only market in North America, but also the big market in China itself.
On the other hand, the PHS in China is a miracle. After sizzling growth in the first half of the decade, China's PHS market is over, with a contraction expected in 2008 or 2009. The slow down occurred as operators turned their attention to laying a foundation for 3G services, expected to roll out this year or in early 2008.
WiMAX may be the next PHS. While the attitude of the Chinese Government towards WiMAX, on which spectrum will be adopted for WiMAX in China, etc., is still not very clear. For Chinese operators, since the 3G network is just about to appear, the relation between WiMAX and 3G will determine the development of WiMAX in China as well.
Whether WiMAX will succeed in Chinese market may also depend on Chinese operators and vendors' participation in the standardization procedure of WiMAX. From the IEEE 802.16 Working Group and WiMAX Forum's point of view, they are trying to encourage and absort more and more Chinese operators and vendors to join in the standardization. The finalization of the WiMAX standards are little bit prolonged awaiting for China to catch up with it. A lot of big companies such as Intel and Samsung are also trying to cooperate with Chinese companies, which also proves that they pay a lot of attention to Chinese market.
In conclusion, this blog made some analysis on the advanced techniques used in WiMAX which is proved to be a very promising network. Based on my knowledge of designing microstrip antenna, the precedure of designing a patch antenna which can be used in WiMAX mobile device is presented. IEEE802.16j, Multi-hop Relay network, as the complement of IEEE802.16, which deals with the disadvantage of Base Station coverage, has attracted a lot of attention. This standard is supposed to be approved at the end of this year. So based on my experience in joining in the sessions of this task group, the developing procedure is provided. WiMAX involves a variety of multi-media applications, such as Television and VoIP, which need high data rate. The implementation of WiMAX system in many countries, especially in China, is analysed, and the perspective and possibility of its development in China is given as well.
