Abstract
Methods, systems, and devices for wireless communications are described. An exemplary method includes receiving a signal corresponding to a frequency band, scanning for communications activity within the frequency band, wherein scanning for communications activity within the frequency band comprises performing a correlation calculation on samples of the signal, and determining whether to attempt a connection establishment within the frequency band based at least in part on the correlation calculation on samples of the signal. When the scanning identifies an indication of activity, a scanning device may attempt to establish a connection with a base station within the frequency band. When the scanning identifies an indication of no activity, a scanning device may refrain from attempting to establish a connection with a base station within the frequency band, and may perform the correlation-enhanced frequency scanning on a different frequency band.
