Assignee: FEDERATED WIRELESS, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A system for managing frequency channels in a shared spectrum available to a radio local access network (RLAN) access point (AP) in a wireless network, the system comprising:
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, cause the system to:
receive a request for channel availability from the RLAN AP to access the shared spectrum;
compute, based on a plurality of parameters associated with the RLAN AP, an RLAN service area (RSA) associated with the RLAN AP;
retrieve one or more incumbent protection contours (IPCs) associated with one or more incumbent users in the shared spectrum, wherein the incumbent users are separate from the wireless network;
identify an IPC, among the one or more retrieved IPCs, that overlaps with the RSA associated with the RLAN AP;
determine, based on the identified IPC, available frequency information corresponding to the received request for channel availability, wherein:
operating frequencies of an incumbent user associated with the identified IPC are unavailable to the RLAN AP, and
the one or more IPCs are pre-computed for the one or more incumbent users of the shared spectrum, wherein the boundary for the one or more IPCs is determined based on user equipment associated with an RLAN AP causes interference above a predetermined threshold;

store the pre-computed IPCs for the one or more incumbent users in a database; and
transmit, to the RLAN AP, a channel availability response comprising the available frequency information.
