What are wireless LAN and cellular network

Wireless LAN is also "WLAN", and cellular network refers to mobile network. In order to let more friends understand the related issues of wireless LAN and cellular networks, here I will give you some popular science.

1: Knowledge of Wireless LAN

Wireless LAN, also known as "WLAN", refers to the use of wireless communication technology to connect various computer devices together. , forming a network system that can communicate with each other and share resources. Simply put, wireless LAN uses wireless connections to make network construction and terminal movement more flexible.

In actual use, the access method of wireless LAN is relatively simple. Take a home wireless LAN as an example. It only needs a router, a computer or terminal (mobile phone or PAD) with wireless capabilities. Its working principle is to connect the hotspot or wired network to the home through the router, perform routing according to the instructions provided by the network operator, then set up a receiving terminal at home (stable range is 20~50 meters), and then turn on the wireless function of the terminal. Enter the user name and password provided by the breadth service provider to access.

2: Knowledge of cellular network

The cellular network, also known as the mobile network, is a mobile communication hardware structure composed of analog and digital cells. Because the signal coverage of each base station that makes up the network is hexagonal, the entire network is like a honeycomb.

The cellular network consists of: mobile stations, base stations, and network subsystems. Mobile stations refer to network terminals such as mobile phones and industrial control devices. The base system includes a mobile base station, a wireless transceiver device, a dedicated network, a wireless digital device, etc.

Uses the 802.11 a/b/g standard, but can also be applied to other radio frequency technologies such as UltraWideband or 802.15.4 Zigbee. Cellular networks do not require centralized switches; only smart access points and network processors are needed to access the Internet.
