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 coexistence data provider in a system for allocating spectrum to spectrum user devices includes an interface configured to receive inputs of available spectrum information, and to receive a plurality of device coexistence data reports that pertain to spectrum usage of the spectrum user devices. A controller is configured to execute a coexistence data application that is stored in a memory and, by execution of the coexistence data application, the coexistence data provider is configured to combine the available spectrum information and the device coexistence data reports to generate a network coexistence report that is indicative of spectrum usage within the one or more networks. Based on the network coexistence report, the coexistence data provider offers spectrum that provides enhanced user device performance. Spectrum user devices also can receive and analyze the network coexistence report, and retune to spectrum that provides enhanced user device performance.

Systems and methods for processing spectrum coexistence information to optimize spectrum allocation

A spectrum use assessment server receives spectrum use data from each of plural electronic devices. The spectrum use data from each electronic device includes at least location of the electronic device and operating channel of the electronic device. The server determines a spectrum use coverage area of each electronic device and identifies an overlap in the coverage areas in which two or more of the electronic devices engage in competing spectrum use.
