The Status Of Wi-Fi

Published:2010/11/2 2:44:00 Author:Li xiao na From:SeekIC

The deployments of WLAN are always in the important places, including the business halls, government, five-star hotels, pedestrian streets, restaurants and coffee shops. The service of WLAN is for the public, and the service of Wi-Fi is mainly for the special demand of group customers. They put the WLAN in the end of customers, such as schools and corporations. The quantity of the large city is not large, and the coverage is not wide enough, therefore, the usage of WLAN in the small cities is still low.

As a supplement of the 3G network, the Wi-Fi is very necessary. More and more Smart phone supports the Wi-Fi, and the use the Wi-Fi to surf the internet is more quickly than the 3G. But the data used by the cell phone is not so much, and the video function, which needs so much flow, is limited by the size of screen and image processing ability; therefore, the 3G network is enough for the basic applications. The maintenance of the Wi-Fi is also very difficult, which needs so much manpower and material resources. We can find out that using the Wi-Fi to separate the flow is good idea, but not practicable. The users of the 3G are always with the strong flowability. If the user stays in the same place for a long time, the wireless 3G network is really unnecessary. The flow of 3G is increasing rapidly, which is not allowed by the network resources. Experts point out the Wi-Fi may solve this problem.

The price of the wireless broadband should not be too low; otherwise, the flow will also increase. When it comes to the profitable model, it is hard to gain the profit within a short period of time. Under the current network environment, the online of many users can not be supported. The capacities of user and broadband are also limited, so the QoS can not be guaranteed. The related integrated circuit is AZD1080.
