Methods are provided for managing frequency channels in a shared spectrum available to a radio local access network (RLAN) access point (AP) in a wireless network. The methods may comprise receiving a request for channel availability from the RLAN AP to access the shared spectrum, computing, based on a plurality of parameters associated with the RLAN AP, an RLAN service area (RSA) associated with the RLAN AP, retrieving one or more incumbent protection contours (IPCs) associated with one or more incumbent users in the wireless network, identifying an IPC, among the one or more retrieved IPCs, that overlaps with the RSA associated with the RLAN AP, determining, based on the identified IPC, available frequency information corresponding to the received request for channel availability, and transmitting, to the RLAN AP, a channel availability response comprising the available frequency information.

Systems and methods for determining channel availability by an automated frequency coordination system

Improved techniques are provided for managing frequency channels in a shared spectrum available to a radio local access network device (RLAN) in a wireless network. A shared spectrum system may perform operations including retrieving a plurality of parameters for one or more high-priority users in the wireless network; computing, based on the retrieved parameters, a plurality of interference-to-noise power ratio (I/N) contour values; storing the plurality of I/N contour values in a database; receiving, from the RLAN in the wireless network, a request for channel availability, wherein the received request includes at least a first value; extracting, based on the first value in the request for channel availability, I/N contour values from the database exceeding a threshold value; determining, based on the extracted I/N contour values, available frequency information corresponding to the received request for channel availability; and transmitting a channel availability response comprising the available frequency information.

Automated frequency coordination for shared spectrum wireless systems

Techniques are provided for managing frequency access in a shared spectrum available to a radio local access network (RLAN) in a wireless network. A shared spectrum system may perform operations including retrieving a plurality of parameters for one or more high-priority users in the wireless network; computing, based on the retrieved parameters, a plurality of interference-to-noise power ratio (I/N) contours; storing the plurality of I/N contours in a database; receiving, from an RLAN device in the wireless network, a request for spectrum availability, wherein the received request includes at least a first value; extracting, based on the first value in the request for spectrum availability, an I/N contour from the database matching RLAN parameters; determining, based on the extracted I/N contour, available frequency information corresponding to the received request for spectrum availability; and transmitting, to the RLAN device, the available frequency information.
