What Is The Difference Between WIFI And WLAN?

WLAN wireless Internet access, its full name is Wireless Local Area Networks, Chinese interpretation is wireless local area network, is a system that uses radiofrequency (Radio Frequency RF) technology for data transmission.

The emergence of this technology is by no means used to replace wired local area networks, but to make up for the shortcomings of wired local area networks to achieve the purpose of network extension, so that wireless local area networks can use a simple access structure to allow users to achieve wireless Network cable, unobstructed network without distance limitation.

WLAN uses the ISM (Industrial, Scientific, Medical) radio broadcast frequency band for communication. The 802.11a standard of WLAN uses the 5 GHz frequency band and supports a maximum speed of 54 Mbps, while the 802.11b and 802.11g standards use the 2.4 GHz frequency band and support maximum speeds of 11 Mbps and 54 Mbps, respectively.

The current protocol standards included in the WLAN include IEEE802.11b, IEEE802.11a, IEEE802.11g, IEEE802.11E, IEEE802.11i, and Wireless Application Protocol (WAP).

What is Wi-Fi?

WIFI (Wireless Fidelity) technology is a brand of wireless network communication technology based on the IEEE 802.11 series of standards. The purpose is to improve the interoperability between wireless network products based on the IEEE 802.11 standard Alliance).
