DUAL BAND COMPOSITE RADIO FOR 6 GHZ
An access point device with a single radio can provide a 6 GHz fronthaul connection to a client device and a 6 GHz backhaul connection to a network device by utilizing a dual-channel composite radio. The dual-channel composite radio comprises a summation circuit for summing transmit signals from the network device and the client device. The output from the summation circuit is fed to a front-end module (FEM) that sends this output to the antenna. The FEM can also receive signals from the network device and the client device and send those signals to the FEM for transmission to a bandpass filter that separates the signals into distinct signals associated with the respective devices. In this way, the cost is reduced and resources are conserved by only requiring a single dual-channel composite radio in an access point device for providing 6 GHz connectivity.
