The secondary use of the frequency band below 1 GHz is gaining a lot of interest for wireless communications due to the attractive propagation characteristics in this band. Optimal reuse relies partially on the reliable detection of unused channels. We propose to detect unused channels based on prediction with the Longley-Rice channel model of which the parameters are tuned thanks to a limited amount of measurements with a low-cost, low-power sensing device.
