System and method for deploying self-coordinated devices in an environment with incumbent receivers
A system in accordance with one aspect mitigates interference with PtPRs (Point to Point Receivers) that may be caused by a Wi-Fi base station or terminal devices associated with the Wi-Fi base station.
1. A communications system comprising:
a first wireless communication network that determines a protection zone for each of a plurality of unintended receivers of a second wireless communication network, wherein a protection zone defines a geographical area where transmission by at least one of a base station and terminal may cause interference with operation of a corresponding at least one unintended receiver;
the first wireless communication network using a location and direction determination module to determine a current location of the base station;
the first wireless communication network determining a current direction in which the antenna of the base station points;
the first communication network determining whether the current location and antenna direction of the base station is within any protection zone of the plurality of unintended receivers and may cause interference with the operation of a corresponding unintended receiver; and
a protection zone system that determines whether transmission is allowed.
2. The communications system of claim 1 , wherein a transceiver in the base station transmits in response to the current location and antenna direction not being within any protection zone of the plurality of unintended receivers.
3. The communications system of claim 1 , wherein the base station performs a local assessment of interference to one or more unintended receivers in response the current location or antenna direction being new or modified, or the information from the ULS (Universal Licensing System) database being new or modified.
4. The communications system of claim 1 , wherein the base station performs a transmission in response to a local assessment of interference concluding that there will be no interference with any of the one or more unintended receivers.
5. The communications system of claim 1 , wherein the base station is prevented from transmitting in response to a local assessment of interference concluding that there will be interference with any of the one or more unintended receivers.
6. The communications system of claim 1 , wherein the interference may be caused by transmission from the base station of the first wireless communication network to a receiver of the second wireless communication network.
7. The communications system of claim 1 , wherein the interference is caused by transmission from a terminal of the first wireless communication network to a receiver of the second wireless communication network.
8. The communications system of claim 5 , wherein preventing the transmission by the base station includes one or more of logging an error message, notifying a system administrator, and/or suggesting different operational parameters for the base station.
9. The communications system of claim 1 , wherein the determining, by the first communication system, whether the current location and antenna direction of the base station is within any protection zone includes testing optional operating parameters for the base station and selecting a set of operational parameters that ensures that the base station does not transmit from within a protection zone of any point to point receiver.
10. The communications system of claim 1 , wherein being within a protection zone of one or more of the plurality of unintended receivers includes determining that an only way to not interfere with one or more point to point receivers includes reducing the transmission power of the base station below a predetermined threshold.
11. The communications system of claim 1 , wherein the determining by the first communication system includes one or more of performing calculations in an internal CPU of the base station, performing calculations in a server or cloud computing resource associated with the base station via a computer network and controlling operations of the base station by external computation services, and jointly performing the determination by a CPU of the base station and the external computation services.
12. A communications device comprising:
a location and direction determination module to determine a current location of a base station and a current direction in which the antenna of the base station points;
a protection zone module to determine whether the current location and antenna direction of the base station is within any protection zone of a plurality of unintended receivers and may therefore cause interference with an operation of a corresponding unintended receiver, wherein a protection zone defines a geographical area where transmission by at least one of the base station and a terminal may cause interference with operation of a corresponding at least one unintended receiver, the protection zone module further preventing transmission by the base station when the current location and antenna direction of the base station is within any protection zone of one or more of the plurality of unintended receivers.
