Abstract

Communication apparatus includes a transceiver configured to communicate over a wireless channel in accordance with both a first and a second communication protocol. The second communication protocol is backward-compatible with the first communication protocol, and has an extended range, which is greater than a nominal range defined by the first communication protocol. A communication controller is configured to generate data frames for transmission by the transceiver, including frame headers in a header format that is compatible both with the first communication protocol and with the second communication protocol. The frame headers include a set of legacy header fields. The communication controller is configured to transmit the legacy fields with a first gain according to the first communication protocol, and to apply a second gain, greater than the first gain, to a transmission of at least one of the legacy header fields for communicating in accordance with the second communication protocol.

Dependent claims

Communication apparatus, comprising:

a transceiver comprising an analog front end and configured to transmit and receive signals over a wireless channel in accordance with both a first communication protocol and a second communication protocol, the first communication protocol defining a nominal communication range, the second communication protocol being backward-compatible with the first communication protocol, and having an extended range, which is greater than the nominal range;
and
a communication controller, which is configured to generate data frames for transmission by the transceiver, including frame headers in a header format that is compatible both with the first communication protocol and with the second communication protocol, the frame headers including a set of legacy header fields, the communication controller being configured to transmit the legacy fields with a first gain according to the first communication protocol, and to apply a second gain, greater than the first gain, by increasing a digital signal value that is input to the analog front end of the transceiver in a transmission of at least one of the legacy header fields for communicating in accordance with the second communication protocol.

A method for communication, comprising:

providing a transceiver that is capable of transmitting and receiving signals over a wireless channel in accordance with both a first communication protocol and a second communication protocol, the first communication protocol defining a nominal communication range, the second communication protocol being backward-compatible with the first communication protocol, and having an extended range, which is greater than the nominal range;
generating data frames for transmission by the transceiver, including frame headers in a header format that is compatible both with the first communication protocol and with the second communication protocol, the frame headers including a set of legacy header fields that are to be transmitted with a first gain according to the first communication protocol;
and
applying a second gain, greater than the first gain, by increasing a digital signal value that is input to an analog front end of the transceiver in a transmission of at least one of the legacy header fields for communicating in accordance with the second communication protocol.
