Abstract
Methods, systems, and devices are described for detecting dedicated short range communications (DSRC) transmissions to determine whether to use at least a portion of the DSRC spectrum. In one embodiment, a multi-mode device may be operated outside of the DSRC spectrum using a first clock rate, and may then be switched to a second clock rate while operating outside of the DSRC spectrum to detect DSRC transmissions using the DSRC spectrum.
