Claim Text:
1. A method, comprising: receiving, on a first frequency, a wireless signal at a particular node in a wireless network from a sending node, the wireless signal including an indication of a duration of the received wireless signal; determining, at the particular node, whether the wireless signal is intended for the particular node before the wireless signal is completely received by examining a header of the received wireless signal to determine whether a destination address within the header corresponds to an address of the particular node; and in response to determining that the wireless signal is intended for the particular node, transmitting, on a second frequency orthogonal from the first frequency, a non-colliding wireless carrier sense detected alert (CSDA) signal from the particular node while the wireless signal is being received to request that other nodes within communication distance of the particular node, except the sending node, refrain from transmitting for the duration of the received wireless signal.
