The lower frequencies will also make detection of white space signals easier and less power-hungry (This is because the higher the frequency detected, the more complex the equipment and the more power required, this explains why your phone’s battery drains faster if Wi-Fi or blue-tooth (Higher freq)is turned on than if you tune to FM stations (lower freq) on the same phone)
