What is the difference between WiFi and WLAN

When it comes to wireless, some people think of wif some people think of WLAN, what is the difference between WiFi and WLAN?

In short, WIFI is the acronym for Wireless Fidelity (wireless fidelity), a technology that allows computers, mobile phones, and so on to interconnect wirelessly.

And WLAN refers to wireless LAN, its coverage can reach 5 kilometers. WiFi is a subset of WLAN, WiFi is a short-range wireless communication technology, and WLAN can build a powerful telecommunications network, layout of multiple AP (hotspot), such as Campus Wireless LAN.

　What's the difference between WiFi and WLAN?

In fact, WiFi is a trademark of the Wlana (Wireless LAN Alliance), which only guarantees that the goods using the trademark can co-operate with each other, not in fact related to the standard itself, but Wi-Fi primarily uses the 802.11B protocol, so people are becoming accustomed to using WiFi to address the 802.11B protocol. In terms of inclusion, WiFi is a standard for WLANs, which are included in WLANs and belong to a new technology in WLAN protocols. WiFi coverage of up to 300 feet (about 90 meters), the largest WLAN (plus antenna) can reach 5KM.

In addition WiFi the biggest advantage is the transmission speed is high, can reach 11Mbps, moreover its effective distance also is very long, simultaneously also with each kind of 802.11DSSS equipment compatible. We know that Bluetooth technology has a very small range of radio coverage, about 50 feet around 15 meters, and WiFi radius of up to 300 feet about 90 meters, in the home or office, with the development of WiFi technology, some WiFi can cover the entire building.

From the actual examples of life can also be seen, WiFi wireless network mainly by routers or wireless card, wireless AP generation, the speed of the distance is very limited, so it is generally only the home or the general use of small and medium-sized enterprises.
