1.WLAN

WLAN Is the abbreviation of wireless local area network , It can be said that this is a technology , Behind every technology is the need for Standards , and WLAN The most common standard is IEEE Of 802.11 Series standard , Of course , Our country also has its own standards , Namely WAPI, and WAPI Than 802.11 Higher standard security .

2.Wi-Fi And WAPI

Wi-Fi That's right 802.11 An implementation of the series of Standards , because Wi-Fi Start early , The commercialization process is developing rapidly , So this field WI-Fi Almost a monopoly , however Wi-Fi Based on unsafe Standards , therefore Wi-Fi Itself is also unsafe , And our national standard WAPI（ Full name ：WLAN Authentication and Privacy Infrastructure, Wireless authentication and security infrastructure ） Relatively safer .
