Abstract

Aspects of the subject disclosure may include, for example, methods and apparatus to configure low power transmitters that operate in unlicensed 6 GHz spectrum in an effort to reduce the likelihood that the low power transmitters will cause interference to incumbent operators of fixed microwave links in the same 6 GHz spectrum. The low power transmitters may be any transmitter in the unlicensed spectrum, including for example, low power indoor access points, 5G small cells, and the like. Other embodiments are disclosed.

Claims (45)

1. A device comprising a first access point, the device comprising:

a processing system including a processor; and

a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:

providing geolocation data of the device to an automated frequency coordination (AFC) system;

receiving, at the device, data identifying at least one frequency channel available for use by the device; and

periodically transmitting, by the device, the data identifying the at least one frequency channel in a Wi-Fi beacon configured to be received at a low power indoor transmitter physically separate from the AFC system.

2. The device of claim 1 , wherein the operations further comprise:

receiving a probe from the low power indoor transmitter; and

providing a probe response to the low power indoor transmitter, wherein the probe response includes the data identifying the at least one frequency channel.

3. The device of claim 2 , wherein the low power indoor transmitter comprises a residential gateway.

4. The device of claim 3 , wherein the residential gateway includes a Wi-Fi access point.

5. The device of claim 3 , wherein the residential gateway includes a 5G small cell.

6. The device of claim 1 , wherein the device operates using unlicensed spectrum in a 6 GHz band, and the at least one frequency channel comprises a list of frequency channels to reduce a possibility of interference to licensed operators using the 6 GHz band.

7. The device of claim 1 , wherein the operations further comprise:

receiving a power limit from the AFC system; and

transmitting the power limit in the Wi-Fi beacon.

8. The device of claim 7 , wherein:

the receiving the power limit comprises receiving a power limit for each of the at least one frequency channel available for use; and

the transmitting the power limit in the Wi-Fi beacon comprises transmitting the power limit for each of the at least one frequency channel available for use in the Wi-Fi beacon.

9. The device of claim 1 , wherein the receiving the data identifying the at least one frequency channel available for use comprises receiving data identifying a plurality of frequency channels available for use.

10. The device of claim 9 , wherein the periodically transmitting the data identifying the at least one frequency channel in the Wi-Fi beacon comprises transmitting the data identifying the plurality of frequency channels in the Wi-Fi beacon.

11. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:

providing geolocation data of a standard power access point to an automated frequency coordination (AFC) system;

receiving, at the standard power access point, data identifying at least one frequency channel available for use by the standard power access point; and

periodically transmitting, by the standard power access point, the data identifying the at least one frequency channel in a Wi-Fi beacon configured to be received at a low power indoor transmitter physically separate from the AFC system.

12. The non-transitory machine-readable medium of claim 11 , wherein the operations further comprise:

receiving a probe from athe low power indoor transmitter; and

providing a probe response to the low power indoor transmitter, wherein the probe response includes the data identifying the at least one frequency channel.

13. The non-transitory machine-readable medium of claim 12 , wherein the low power indoor transmitter comprises a residential gateway.

14. The non-transitory machine-readable medium of claim 13 , wherein the residential gateway includes a Wi-Fi access point.

15. The non-transitory machine-readable medium of claim 13 , wherein the residential gateway includes a 5G small cell.

16. The non-transitory machine-readable medium of claim 11 , wherein the standard power access point operates using unlicensed spectrum in a 6 GHz band, and the at least one frequency channel comprises a list of frequency channels to reduce a possibility of interference to licensed operators using the 6 GHz band.

17. A method, comprising:

providing, by a standard power access point including a processor, geolocation data of the standard power access point to an automated frequency coordination (AFC) system;

receiving, by the standard power access point, data identifying at least one frequency channel available for use by the standard power access point; and

periodically transmitting, by the standard power access point, the data identifying the at least one frequency channel in a Wi-Fi beacon configured to be received at a low power indoor transmitter physically separate from the AFC system.

18. The method of claim 17 , further comprising:

receiving, by the standard power access point, a power limit from the AFC system; and

transmitting, by the standard power access point, the power limit in the Wi-Fi beacon.

19. The method of claim 18 , wherein:

the receiving the power limit comprises receiving a power limit for each of the at least one frequency channel available for use; and

the transmitting the power limit in the Wi-Fi beacon comprises transmitting the power limit for each of the at least one frequency channel available for use in the Wi-Fi beacon.

20. The method of claim 17 , wherein:

the receiving the data identifying the at least one frequency channel available for use comprises receiving data identifying a plurality of frequency channels available for use; and

the periodically transmitting the data identifying the at least one frequency channel in the Wi-Fi beacon comprises transmitting the data identifying the plurality of frequency channels in the Wi-Fi beacon.
