Abstract
Communication apparatus includes a transceiver configured to transmit and receive signals over a wireless channel in accordance with both a first communication protocol and a second communication protocol. The second communication protocol is backward-compatible with the first communication protocol, while defining an enhanced communication bandwidth that is at least twice the nominal communication bandwidth of the first communication protocol. A communication controller generates data frames for transmission by the transceiver, including frame headers in a header format that is compatible with both the first communication protocol and the second communication protocol, such that the frame headers are transmitted within the nominal communication bandwidth. The data frames that are transmitted in accordance with the second communication protocol have first and second frame headers that are transmitted in parallel in respective first and second sub-bands of the enhanced communication bandwidth.
