1. A spectrum management server, comprising:
a communications interface over which communications with a secondary user of spectrum are made, the secondary user having a need for spectrum access to carry out wireless communications and the communications including receiving a spectrum access request from the secondary user; and
a processor that executes logical instructions to configure the spectrum management server to:
determine a primary user that has a protected use area that overlaps with a secondary use area of the secondary user;
divide the protected use area of the primary user into geographic pixels of predetermined area, each pixel being located within or overlapping with at least one geographic contour and having a corresponding predetermined limit for interference under which operation of the secondary user is tolerable, wherein a value of the corresponding predetermined limit for interference is based at least in part on a protection level associated with an innermost contour of the at least one geographic contour;
for each pixel having overlap between the protected use area and the secondary use area, determine a quantified predicted amount of interference that operation of the secondary user has on a primary channel of the primary user;
authorize spectrum access to the primary channel of the primary user under interference rights to the secondary user if the quantified predicted amount of interference for each pixel having overlap between the protected use area and the secondary use area does not exceed the corresponding predetermined limit for interference; and
communicate the spectrum access to the secondary user.
