ABSTRACT:
Method and apparatus for providing a multi-channel, multi-user wireless intercom, comprising a plurality of multi-channel wireless transceiver radios configured to form a radio unit. Each user in a group of users employs a radio unit to communicate with other users in the group. Users may selectively communicate with another user or broadcast simultaneously to all users in the group. Additionally, subnets between users may be formed where communications take place among a number of selected users comprising less than the entire group of users. Receive and transmit audio combiners are employed such that users can hear communications traffic on one or more channels and transmit on one or more channels, simultaneously.
