identify a location of the apparatus;
obtain spectrum usage data from a database, the spectrum usage data indicating a licensed entity licensed within an area including the location of the apparatus to communicate across a first sub-band of frequencies within a frequency band, the frequency band including a plurality of channels each having a fixed width;
determine a modified transmission power using the spectrum usage data, the modified transmission power configured to reduce interference with the licensed entity on the first sub-band; and
conduct wireless transmissions on at least one of a first set of one or more of the plurality of channels containing the first sub-band or an adjacent channel that is adjacent to the first set of channels at the modified transmission power.
