What does WLAN mean in mobile phones?

A WLAN in a mobile phone is a wireless local area network.

WLAN is the abbreviation of wireless local area network, which refers to the application of wireless communication technology to interconnect computer equipment to form a network system that can communicate with each other and share resources.

The essential feature of WLAN is that computers are no longer connected to the network through communication cables, but through wireless mode, thus making network construction and terminal movement more flexible. ?

It is a very convenient data transmission system, which uses radio frequency (RF) technology and electromagnetic waves to replace the traditional local area network composed of twisted-pair copper wires to communicate in the air, so that the wireless local area network can make users pass through it with a simple access structure and achieve the ideal state of "information portability and convenience".

The difference between WLAN and WiFi:

First of all, the full name of WLAN is "WLAN", which is translated into Chinese as "WLAN". As a data transmission system, WLAN has a general standard IEEE 802. 1 1 series.

The WLAN of mobile phone actually includes two ways to surf the Internet, one is WiFi and the other is WAPI. In contrast, WiFi is more stable and reliable, while WAPI is more secure.

In daily life, in fact, WiFi and WLAN are directly distinguished. WLAN has a wider radio coverage, while WiFi is modified on the basis of IEEE 802. 1 1 series standards. Although more stable, the coverage is smaller.

Therefore, WLAN is more suitable for use in large public areas, while WiFi is suitable for use in offices and homes.
