Patent ID: 8879527

Claim:
A communications processor for a wireless LAN operative with a plurality of sub-channels forming a master channel, the communications processor having: a network processor; a plurality of sub-channel processors, each sub-channel processor having a receive path whereby energy coupled to an antenna for reception of wireless data is directed, in sequence, to a bandpass filter, a transmit/receive switch, an RF transceiver having a mixer and receive local oscillator for down-conversion of received modulated frequencies within frequency limits of said bandpass filter, an analog front end for digitizing of said modulated frequencies to baseband, a baseband processor for formation of said baseband modulated frequencies into demodulated data for transfer to said network processor using a media access controller, the each sub-channel processor also having a transmit path whereby data from said network processor is coupled, in sequence, to said media access controller and to said baseband processor for baseband modulation of said transmit data, said analog front end for digitizing said baseband modulation, said RF transceiver for mixing with a transmit local oscillator to a modulated transmit frequency, thereafter to a power amplifier and said transmit/receive switch, to said bandpass filter and to said antenna; said network processor coupled to each of said sub-channel processors, said bandpass filter and said transceiver mixer operative on a unique one of sub-channel frequencies and at least two of said plurality of sub-channel processors simultaneously sending or receiving wireless packets.
