Protocol Compare

802.11 band.png
Type Band Conditon Channel Speed Maximium Speed Actual Speed Note
802.11/n 2.4/5G (low speed 5G) 4 channels, 40Mhz 150Mbps 600Mbps ~300 Mbps
802.11/ac 5G 4(up to 8) channels, 40Mhz (up to 166Mhz) 866Mbs 8*866Mb (7Gbps) ~3Gbps Support mutiple user
  • Most cell phone work at 150Mbps, mutiple phones will connect to route, then route will work at 150Mbps
  • 802.11ac 1T1R (433Mbps)
  • 802.11n 2T2R (300Mbps)

Working Mode

STA / AP / STA + AP three operating modes.
  • ♦ STA mode: modules are connected via a router Internet, mobile phone or computer via the Internet to the device's remote control.
  • ♦ AP mode: module as a hot spot, to achieve mobile phone or computer directly communicating with wireless control for LAN.
  • ♦ STA + AP mode: two modes of coexistence mode, which can be controlled via the Internet can seamlessly switch for easy operation.
