1. A virtual channel system for wireless, multi-channel signaling, comprising:
- a framer receiving a multiple channel signal, comprising;
a framing circuit configured to frame the received multiple channel signal to form channel frames that each have a plurality of overhead bits and a plurality of data bits including data from one of the received channels, and to incorporate a virtual channel which is communicated via a plurality of channel frames, the framing circuit including a timing logic circuit to provide clock signals for the insertion of at least the overhead bits into the channel frames, and a signaling controller configured to provide virtual channel signals to the framing circuit, wherein a plurality of virtual channel signals form a message for sending on the virtual channel;
a wireless transmitting system converting the overhead and data bits of the channel frames into transmitted wireless signals;
a wireless receiving system converting the transmitted wireless signals back into the channel frames; and
a deframer receiving the channel frames, extracting the virtual channel signals therefrom, and forming the multiple channel signals as received by the framer.

Abstract
A system and method providing a frame structure to received channel data sent over an air interface of a wireless communication system. The system and method may allow compensation for transmitting and receiving frequency variations, synchronization at the receiver, and provides a virtual signaling channel which may be used for system alarms and status. In one embodiment, the system uses bit stuffing, a frame preamble and a signaling preamble to transmit data at a high data rate in the ISM band.
