Abstract:
1. A first network device comprising: a transceiver configured to receive a first packet broadcast from a second network device to a plurality of network devices via a channel, wherein a bit in the first packet indicates a request for a condition of the channel, and wherein the plurality of network devices include the first network device; a circuit configured to determine the condition of the channel based on the bit in the first packet indicating the request for the condition of the channel; and a controller configured to, prior to the circuit determining the condition of the channel and in response to the bit in the first packet indicating the request for the condition of the channel, transition the circuit from an inactive state to an active state, wherein the controller is configured to, subsequent to the circuit determining the condition of the channel, return the circuit to the inactive state, the transceiver is configured to, subsequent to the circuit returning to the inactive state, transmit a second packet to the second network device, and the second packet indicates the condition of the channel.
