Granting interference rights to a secondary spectrum user that has a need for spectrum access to carry out wireless communications includes receiving a spectrum access request from the secondary user and determining a primary user that has a protected use area that overlaps with a secondary use area of the secondary user. A quantified predicted amount of interference that operation of the secondary user has on the primary channel of the primary user is determined and spectrum access to a primary channel of the primary user under interference rights is authorized if the quantified predicted amount of interference has less than a predetermined amount of effect on the primary channel of the primary user. The spectrum access is communicated to the secondary user.

System and method for management of spectrum interference rights and secondary use permissions

Systems and methods to reduce control data traffic between a hub radio device (e.g., a master white space device) and spoke radio devices (e.g., slave white space devices). Reduced are the number of control messages and/or the amount of data transmitted in control data messages. The hub radio device stores data regarding the spoke radio devices that register for white space access (e.g., specific spectrum access credentials) with a spectrum management server via the hub radio device. As long as conditions regarding a spoke radio device remain relatively unchanged, the stored data for the spoke radio device may be used to maintain the white space access through periodic renewal of the corresponding channel authorization with the spectrum management server.

System and method for reducing control data traffic in a white space network

Generic access credentials for use by a spoke radio device in communications with a hub radio device to acquire specific access credentials for the spoke radio device are determined by a spectrum management server to minimize the possibility of creating undesirable interference to other radio systems. The spectrum management server determines a coverage area of the hub radio device and determines sub-regions of the coverage area; determines a generic access transmit power limit for each sub-region of the coverage area for one or more channels on which the hub radio device has access rights to engage in wireless communications; and transmits the generic access transmit power level for each sub-region and channel combination to the hub radio device.

System and method for mitigating interference when initializing links between cognitive radios

Managing spectrum use in a managed area where spectrum use is carried out by an incumbent user on an intermittent basis includes sensing spectrum use in the managed area and determining that the incumbent spectrum user is actively using spectrum in the managed area by analyzing sensor data. A spectrum use policy associated with characteristics of the determined spectrum use is made and one or more secondary spectrum users are notified that spectrum defined in the identified policy is unavailable for use by the one or more secondary users.

System and method for policy-based spectrum management

A spectrum management server generates and an electronic device uses a channel map solution for a predetermined travel route of the electronic device. The channel map solution includes at least one available channel for each of the plural geographic areas through which the planned travel route passes. At least two adjacent ones of the geographic areas have different channel availability.

Systems and methods for determining and specifying spectrum availability for a predetermined travel route

Systems and methods to facilitate acquisition of specific operating parameters by a spoke radio device via a hub radio device while the hub radio device operates using specific operating parameters and the spoke radio device operates using generic operating parameters. The spoke radio device may acquire the generic operating parameters from a beacon broadcast by the hub radio device. If a link between a hub radio device and a spoke radio device cannot be satisfactorily established and maintained using the specific and generic operating parameters, respectively, then the hub radio device may use alternative channels and/or reduce its operational area to attempt to converge specific and generic transmit power levels for improved link establishment.

System and method for optimizing channel characteristics when initializing links between cognitive radios in a shared spectrum environment

Allocating spectrum to a secondary radio device includes determining a contour separation distance for the secondary radio device. The contour separation distance is a function of a minimum separation distance from protected areas of primary radio devices and an accuracy variance for the secondary radio device. The accuracy variance is specified as a distance and is a function of accuracy information for a reported location of the secondary radio device. If a distance between a contour of a protected area for a primary radio device and the reported location for the secondary radio device is less than the contour separation distance, a channel used by the primary radio device is not available for use by the secondary radio device for wireless communications. Otherwise the channel used by the primary radio device is available for use by the secondary radio device for wireless communications.
