China WiFi


What is Wi-fi?

China Wifi is wireless networking - the ability to connect to a network or PC using radio signals (as opposed to network cabling). It's faster and has a greater range than Bluetooth, and is ideal for home or office connectivity. Using a wi-fi setup with your PDA or laptop means that you can share a broadband Internet connection, swap files, or share a printer or storage area between computer users.

In Shanghai, China Telecom has created China WiFi hotspots in over 4,000 public places. WiFi hotspots are expected to cover over 5,000 public places by the end of this year, forming a high-speed seamless broadband network that will cover the whole city.

China Wifi comes in two speeds: 802.11b (data transfer rates up to 11 megabits per second) or the newer 801.11g standard that goes up to 54 megabits per second. This compares with Bluetooth's much slower speed of 0.57 megabits per second. There's a newer standard, 802.11n being phased in that offers even faster connectivity.

Wifi 802.11b/g operates in the 2.4GHz frequency band (also used by Bluetooth and microwave ovens), and has a typical range of around 500 feet (with clear line of sight). Indoors, you can expect around 150 feet with 802.11 - this will increase with the 802.11n protocol.
