A vehicle includes a Wi-Fi system for transmitting a signal. The Wi-Fi system includes a channel having a primary subchannel and one or more secondary subchannels. A sensor measures energies of signals in the primary subchannel and in each of the one or more secondary subchannels. A processor determines that the primary subchannel is idle when the energy in the primary subchannel is less than a primary subchannel energy threshold, assigns a score to each of the one or more secondary subchannels based on the secondary subchannel energy, calculates a sum of the scores, and transmits the signal over the channel when the sum of the scores is less than a score threshold.
