Communication equipment refers to wired communication device and wireless communication device used in industrial control environment.
Wired communication equipment mainly introduces the serial port communication, professional bus communication, industrial Ethernet communication and conversion equipment between various communication protocols, mainly including routers, switches, modems and other equipment.
Wireless communication equipment mainly includes wireless AP, wireless bridge, wireless network card, wireless lightning arrester, antenna and other equipment.

The biggest advantage of wireless communication device is the environment. It does not need to be limited by the line. It has a certain degree of mobility. It can communicate through wireless connection in a mobile state, with low construction difficulty and low cost; However, wireless communication device has weak anti-interference, slow transmission rate, limited bandwidth, limited transmission distance and low cost. However, wireless communication is changing the corresponding technology to make the transmission rate higher (the rate of 802,11n can reach 100Mbps and not lower than wired communication), more stable and convenient, so wireless communication device will be the development trend.

Wired communication equipment:
Commonly used cable communication equipment includes: computer, TV, telephone, PCM, optical transceiver, server, etc
Wireless communication equipment:
Satellite, radio station, wireless TV (on bus or subway), wireless LAN, mobile phone (mobile phone), mobile GPRS internet access, etc.
