Wi-Fi is commonly known as wireless broadband
The full name is Wireless Fidelity. 802.11b is sometimes mistakenly labeled as Wi-Fi. In fact, Wi-Fi is a trademark of the Wireless LAN Alliance (WLANA). This trademark only ensures that products using this trademark can cooperate with each other and has nothing to do with the standard itself. . But later people gradually became accustomed to using WIFI to call the 802.11b protocol. Its biggest advantage is that the transmission speed is high, which can reach 11Mbps. In addition, its effective distance is also very long, and it is also compatible with various existing 802.11DSSS devices. Laptop technology - Centrino technology is based on this standard.
WAPI standard
WAPI is a wireless LAN security technology standard independently developed by my country with independent intellectual property rights.
WAPI is the English abbreviation of WLAN Authentication and Privacy Infrastructure. It is a type of wireless transmission protocol like infrared, Bluetooth, GPRS, CDMA1X and other protocols. The only difference is that it is a transmission protocol in wireless local area network (WLAN). It is different from the current 802.11B transmission protocol. The protocols are relatively similar.
The difference between WAPI and Wi-Fi
There are many wireless LAN transmission protocols, including 802.11A, 802.11B, 802.11G, 802.11i, etc., which are developed by the American WI -The FI organization develops and conducts certification, while WAPI is reviewed and approved by the IEEERegistrationauthority authorized by ISO/IEC. The biggest difference between the two is the different security encryption technologies; WAPI uses a security protocol called "Wireless LAN Authentication and Privacy Infrastructure (WAPI)", while 802.11B uses "Wired Enhanced Equivalent Privacy (WEP)" "Safety Protocol. For individual users, the biggest benefit from the emergence of WAPI is to make their laptops more secure.
