(57) ABSTRACT A central registration system provides channel maps of avail able spectrum
to radio devices based on feedback and spec trum allocation policies. Each available …

A registration system for secondary radio systems that use spectrum that is interleaved with
spectrum used by primary radio systems may include an interface to communicate with the …

A method and system for controlling access to a spectrum resource by radio devices that are
grouped into a first class and a second class, the first class having higher priority to the …

Spectrum asset class determination is dynamically assessed so that a radio device may use
a more preferred one of licensed spectrum or unlicensed spectrum for the specific wireless …

Disclosed are techniques for managing situations where spec trum use by one party is
preempted by spectrum needs of another party. A revocation may be sent from a spectrum …

The invention includes a method and apparatus for dynami cally allocating spectrum
available within a region including a plurality of base stations. The method includes …

A method and system for coordinated dynamic access to radio spectrum for wireless
networking includes defining a coordinated access band (CAB) from which radio access …

BACKGROUND There has been a considerable amount of interest in dynamic allocations of
radio spectrum. In traditional licensed 15 models for radio spectrum, the task of how radio …

An unlicensed RF data delivery system uses interference characterization to adapt the RF
transmission to accommo date the interferences. It uses at least one detection system to …
