What does WAPI and Wi-Fi mean. And what's the difference?

Wireless network, is the use of radio waves as a medium of information transmission of the wireless local area network (WLAN), and the use of wired network is very similar, the biggest difference is the different transmission media, the use of radio technology to replace the network cable, and the cable network for each other backup.

Wi-Fi is commonly known as wireless broadband

Full name wirelessfidelity. 802.11B is also sometimes incorrectly marked Wi-Fi, in fact Wi-Fi is a trademark of the Wireless LAN Federation (WLANA), which only guarantees that the goods using the trademark can co-operate with one another, and that the standard itself does not actually matter. But then people became accustomed to using WiFi to address the 802.11B protocol. Its biggest advantage is the high transmission speed, can reach 11Mbps, in addition its effective distance is also very long, but also with a variety of 802.11DSSS equipment compatible. The technology of notebook computer-Centrino technology is based on this standard.

WAPI Standard

WAPI is the English abbreviation of wlanauthenticationandprivacyinfrastructure. It is like infra-red, Bluetooth, GPRS, cdma1x and other protocols, is a wireless transmission protocol, but unlike them is that it is a wireless local area network (WLAN) a transport protocol, it and the current 802.11B transmission protocol is similar.

So why set the standards for a transport protocol? We know that different transport protocols will package the data in two the above electronic devices for transmission between the principle and the means of implementation are different, most of them are incompatible, if not set the standard of wireless transmission protocol, wireless electronic equipment, the universality will be greatly limited, For example, your laptop in a place may be able to wireless internet access, but to the B place, may be due to the transmission protocol is not uniform and wireless internet can not be achieved, and if all wireless products use the same transmission protocol, then, your laptop wherever you go, Wireless Internet access can be easily achieved wherever there is a WLAN signal.

The difference between WAPI and Wi-Fi

There are many kinds of wireless LAN transmission protocols, including 802.11A, 802.11B, 802.11G, 802.11i and so on, it is established by the United States Wi-Fi organization and certification, and WAPI by the iso/ The Ieeeregistrationauthority review authorized by IEC has been approved. The biggest difference between the two is that security encryption technology is different; WAPI uses a security protocol called Wireless LAN authentication and Confidentiality infrastructure (WAPI), while 802.11B uses the wired Enhanced Equivalent Privacy (WEP) security protocol. For individual users, the biggest benefit of WAPI is making their laptops more secure.

WAPI is China's independent research and development, with independent intellectual property rights of wireless LAN Security technology standards.
