Abstract
A first node includes a transceiver configured to detect one or more second nodes that transmit one or more signals on a channel of an unlicensed frequency band. The one or more signals have one or more received signal strengths at the first node that are below an energy detection threshold that indicates the channel is clear for transmission by the first node. The first node also includes a processor configured to modify the energy detection threshold based on the received signal strength.
