The 2T2R adopts a dual-antenna technology, and the two antennas are respectively responsible for receiving and transmitting, and in a broad sense, the two antennas can be understood as dual-channel transmission, so that the transmission efficiency of the local area network can be improved by 50% or even more than 100%, and thus the transmission speed can reach 11G IEEE, and the local area network rate can reach 150M-300M, and the selection of 2T2R wireless network equipment is a better choice today when network applications are increasingly developed.
