Abstract

“Tiered” groups of devices (tiered service radios) and/or licenses associated with the devices or users so as to provide a hieratical set of interference protection mechanisms for members of each tier of service are disclosed. Point-to-point and point-to-multipoint data links for any communication application, including wireless backhaul applications, are also disclosed. Exemplary systems, devices, and methods disclosed herein allow for the efficient operation of such a tiered service. Interference protection among tiered service devices belonging to one or more tiers of the service, from other devices within the same tier of service, or devices of other tiers of service, is disclosed. Identification of other devices of the same or differing tiers of service, and interference mitigation between other tiered service devices based upon intercommunication between the devices, and/or via a central registry database, are also disclosed.
