Abstract
A Spectrum Sharing System (SSS) is a system and method which allows Radio Frequency (RF) wireless mobile and fixed devices to operate in the 3100-3650 MHz frequency band while simultaneously protecting radar operations from interference. The SSS includes equipment which utilizes spectrum sensing, GPS data, and database technology to provide a solution by which mobile and fixed wireless devices can be allowed use of the 3100-3650 MHz frequency band and share same spectrum with radar systems. The spectrum sharing action is only possible when radar emissions are not detected within the licensed service in the 3100-3650 MHz spectrum, and SSS has determined that geographical area of interest is not occupied by radar systems.
Claims20
A method for creating a spectrum sharing system (SSS) to control spectrum access and spectrum sharing of first networked wireless devices by identifying the presence of radar signals in a predetermined frequency band within a defined geographic area, the method comprising:
- a) establishing a spectrum service, the spectrum service being a licensed spectrum service using licensed devices;
- b) selecting a spectrum service;
- c) establishing at least a first and second level of service for the first networked wireless devices, wherein the first level corresponds to priority access and the second level corresponds to general access;
- d) providing a spectrum sensor by itself and/or in conjunction with another SSS wireless network component, wherein the spectrum sensor operates in the selected spectrum service and controls spectrum access for the first networked wireless devices, the spectrum sensor by itself and/or in conjunction with another SSS wireless network component further:
- i) detects radar signals, ii) identifies the characteristics of the radar signals, iii) establishes at least one radar signal in the predetermined frequency band and determines and identifies radar signals that are in compliance with or not in compliance with the predetermined frequency band, iv) identifies first network wireless devices that cause interference with the at least one radar signal predetermined frequency band, v) establishes geographical longitudinal and latitudinal boundaries around each of the identified first networked wireless devices wherein such boundaries operate as protection zones wherein all identified enclosed wireless devices will not operate within the at least one radar signal predetermined frequency band, vi) exchanges, transmits, or receives data regarding protection zones for second networked wireless devices, vii) allows or denies spectrum access to first networked devices upon presence or lack of presence of radar signals in the predetermined frequency band, and viii) terminates the protection zones upon radar signals no longer being detected or a time period has passed after the radar signals had been detected;
- e) determining alternate spectrum available to the first networked devices;
- f) establishing a timeframe for the first network devices to move to the alternate spectrum or to cease operation;
- and
- g) determining whether a resumption of service to the first network wireless devices should occur.
