Method and system for establishing a channel for a wireless video area network

A coordinator for channel control in a wireless video area network, comprising:

• a scanning module configured for scanning available channels, for first scanning low-rate (LR) channels by performing energy detection for each LR channel for a time period, and for determining a LR peak energy detection value for each LR channel;
• a selection module configured for selecting a channel from the available channels with minimal interference with other networks;
• and
• a communication module configured for starting communication on the selected channel if the selected channel remains available for a listening period, wherein the available channels include high-rate (HR) channels and the LR frequency channels, such that m HR channels in a general frequency band are defined, and n LR channels are defined in the same frequency band as the HR channels, such that within each of the HR channels, a number n of LR channels are defined.
