Td-scdma Integration With The WLAN Network Analysis And Application Of Key Technologies In The Construction

With the development of mobile internet, it becomes possible to access the internet anytime and anywhere. And mobile users have been paying more attention to the speed of internet. Indeed, TD-SCDMA initially satisfies the users'needs; however, it shows some shortcomings as well, such as not supporting large number of people using simultaneously, and not allowing the application in the hotspot. This imposed much more burden to China Mobile, who hopes to find a new tech to compete with WCDMA and CDMA2000. Under this circumstance, to apply the converged network mixing TD with WLAN could be the first option to China Mobile.This paper first introduces the tech of TD-SCDMA and WLAN, then analyzes the issues about how TD-SCDMA handles with the qualification of high-band and high-density mobile broadband. At the same time, it illustrates the current status of WLAN after it experienced the recent development. Then, the paper focus the comparison among multiple converged network and brings forward an efficient plan for operators, taking many factors into account, such as the transformation of handsets (from laptop,netbook,PDA to WI-FI phone). The plan especially emphasizes the concept from the extension of fixed broadband to the supplement of cellular network. Additionally, the paper justifies the security factor, which is the most significant factor to operators. Enclosed with the paper it shows the good example extracted from the ShanXi Province China Mobile company, including network plan, network management and network operation. Last not the least, the paper gives some advices to help operators to fasten the speed of instruction of TD+WLAN network, to upgrade the capacity of network and win in the new competitive market.
