Ask the network masters about the explanation of wireless technical terms.

82.11 is the standard of wireless network connection, which is what we usually call WIFI. 82.11b refers to the rate standard of 11M, 82.11g refers to the rate standard of 54M and 82.11n refers to the rate standard of 15M. They backwards compatibility.

AP is short for Access Point, which is generally translated as "wireless access node". It mainly provides wireless workstations with access to wired LAN and from wired LAN, and wireless workstations within the coverage of access point can communicate with each other through it. Generally speaking, wireless AP is a bridge between wireless network and wired network. Because the coverage of wireless AP is a circular area that spreads outward, it should be placed in the center of the wireless network as far as possible, and the straight-line distance between each wireless client and the wireless AP should not exceed 3 meters to avoid communication failure due to excessive attenuation of communication signals.

MIMO (Multiple Input Multiple Output) is an antenna technology for wireless communication. In this technology, multiple antennas are used for both source (transmitter) and destination (receiver). The antennas at each end of the communication loop are combined to achieve the minimum error and the optimal data transmission speed. MIMO is one of several forms of smart antenna technology, and the others are MISO (Multiple Input, One Output) and SIMO (Multiple Input, Multiple Output).
