System and method for monitoring and enforcing a restricted wireless zone
First Claim
1. A method for monitoring for unauthorized radio frequency energy, comprising:
- a. receiving radio frequency energy in a region that encompasses at least a zone in which it is desired to monitor for unauthorized radio frequency energy; and
b. analyzing at least one characteristic of the received radio frequency energy to determine whether unauthorized radio frequency energy is occurring in the zone.

Abstract
Monitoring for unauthorized RF energy emitted or transmitted in a particular zone or portion of a building, etc. Radio frequency energy is received in a region that encompasses a zone in which it is desired to monitor for unauthorized radio frequency energy. At least one characteristic of the received radio frequency energy is analyzed to determine whether unauthorized radio frequency energy is occurring in the zone. Unauthorized RF energy may be detected by analyzing at least one spectral characteristic of the received radio frequency energy and comparing the at least one spectral characteristic with data associated with authorized and/or unauthorized radio frequency energy. Alternatively, signal classification techniques can be applied to data derived from the received radio frequency energy to classify by type signals contained in the received radio frequency energy. Certain signal types may be designated as unauthorized in a particular restricted zone and the results of the signal classification analysis is compared with data for authorized and/or unauthorized signal types.

24. A system for monitoring for unauthorized radio frequency energy, comprising:
-
a. a plurality of radio sensor devices each at a corresponding position in a region that encompasses a zone in which it is desired to monitor for unauthorized radio frequency energy, wherein each radio sensor device receives radio frequency energy and analyzes at least one characteristic of the radio frequency energy it receives to determine whether unauthorized radio frequency energy is occurring; and
b. a computer connected to each of the plurality of radio sensor devices that receives data from the radio sensor devices concerning radio frequency energy that they monitor, and wherein the central computer correlates the data received from the radio sensor devices with respect to unauthorized radio frequency energy determined to be occurring in the zone. - View Dependent Claims (25)
