Title: DATA BROADCASTING WITH A PREPARE-TO-BROADCAST MESSAGE
Abstract:
Techniques for broadcasting data in a multi-channel network having a control channel and multiple data channels are described. A node wishing to broadcast data may determine a particular data channel from among the multiple data channels, a modulation technique, and a data rate to be utilized to broadcast the data. The broadcasting node may transmit a message over the control channel indicating that the data will be broadcast on the particular data channel using the modulation technique and at the determined data rate. The broadcasting node and a node wishing to receive the data may switch to the particular data channel. The broadcast node may broadcast the data over the particular data channel, while the receiving node may receive the data. After broadcasting the data or a predetermined time period has expired, the broadcasting node and receiving node may switch to the control channel.
