Abstract: A spectrum access system (SAS) and policy engine (PE) application are provided that facilitates the detection, classification and protection of a non-informing spectrum user in a spectrum sharing environment. The SAS may contain a policy database. Wireless access points with an embedded PE software application may retrieve a spectrum policy configuration specific to their immediate location and capabilities and may use the policy configuration to efficiently detect, classify and protect a non-informing spectrum user from radio frequency interference without disclosing details about the detected spectrum operations.

Abstract: This disclosure describes a novel method for price discovery of a spectrum license. Calculated metrics and other local information may be combined with previous transaction prices to calculate a fair market value. The published market value of one license may be updated according to a feedback mechanism influenced by transactions of other licenses. The invention enables a market-making party to establish an objective fair market price and to support single-bid or sparse-bid spectrum auctions.

Abstract: A method is provided to partition and distribute application processing across a plurality of nodes wherein the selection of a node is made according to that node's geographic area of responsibility. In a client/server environment application processing requests are received by a primary application node and may be routed or forwarded to one or more partitioned application nodes according to request location information and a partitioning assignments database.

Abstract: A Environmental Sensing Capability (ESC) is provided that facilitates the protection of a non-informing incumbent spectrum user in a dynamic spectrum sharing environment. The ESC, which consists of a plurality of spectrum sensors, may establish a geographic partitioning strategy within which each partitioned geographic service area may be individually managed according to a finite state machine. Incumbent users may receive radio frequency interference protection without disclosing the details of their spectrum operations.
