Abstract

Techniques for dynamically selecting filter parameters for a multi-radio multi-band configuration are described. An example technique includes determining a device class associated with a computing device comprising a plurality of radios operating on a plurality of bands. One or more target operating parameters of the computing device are determined based at least in part on the device class. One or more filter parameters of a plurality of filters for operating the plurality of radios are determined based at least in part on the one or more target operating parameters. The plurality of radios are configured according to the one or more filter parameters.

First claim

We claim:

1 . A computer-implemented method comprising:
determining a device class associated with a computing device comprising a plurality of radios operating on a plurality of bands; determining one or more target operating parameters of the computing device, based at least in part on the device class; determining one or more filter parameters of a plurality of filters for operating the plurality of radios, based at least in part on the one or more target operating parameters; and configuring the plurality of radios according to the one or more filter parameters.

2 . The computer-implemented method of claim 1 , wherein the device class is one of the following types: (i) low power indoor (LPI)-only, standard power (SP)-only, and LPI and SP capable.

3 . The computer-implemented method of claim 1 , wherein determining the one or more target operating parameters comprises determining at least one of: (i) a target power budget for the computing device or (ii) a target back-off for each of the plurality of filters, when the device class is low power indoor (LPI)-only.

4 . The computer-implemented method of claim 1 , wherein determining the one or more filter parameters comprises determining a center frequency for each of the plurality of filters.

5 . The computer-implemented method of claim 1 , wherein determining the one or more target operating parameters comprises determining at least one of: (i) a target power budget for the computing device, (ii) a channel allowance, or (iii) a Q factor associated with each of the plurality of filters, when the device class is standard power (SP)-only or low power indoor (LPI)-only and SP capable.

6 . The computer-implemented method of claim 5 , wherein the target power budget and the channel allowance are based on input received from an automated frequency coordination (AFC) system.

7 . The computer-implemented method of claim 1 , further comprising:
determining a configuration of the plurality of bands for the plurality of radios; and configuring the plurality of radios according to the configuration.

8 . The computer-implemented method of claim 7 , wherein the configuration is determined based at least in part on a first number of channels allowed for standard power operation in a first band and a second number of channels allowed for standard power operation in a second band.

9 . The computer-implemented method of claim 8 , wherein the configuration is determined based at least in part on a power budget for each of a plurality of bands.

10 . The computer-implemented method of claim 8 , wherein:
the first band is 5 gigahertz (GHz) band; and the second band is 6 GHz band.

11 . The computer-implemented method of claim 10 , wherein the configuration comprises (i) dual radios operating on the 5 GHz band or (ii) dual radios operating on the 6 GHz band.

12 . The computer-implemented method of claim 1 , wherein:
the plurality of radios comprises four radios; and the plurality of bands comprises three bands.

13 . The computer-implemented method of claim 12 , wherein:
a first radio of the plurality of radios operates on a 2.4 gigahertz (GHz band); a second radio of the plurality of radios operates on a 5 GHz band; a third radio of the plurality of radios operates on the 5 GHz band; and a fourth radio of the plurality of radios operates on a 6 GHz band.

14 . The computer-implemented method of claim 12 , wherein:
a first radio of the plurality of radios operates on a 2.4 gigahertz (GHz band); a second radio of the plurality of radios operates on a 5 GHz band; a third radio of the plurality of radios operates on a 6 GHz band; and a fourth radio of the plurality of radios operates on the 6 GHz band.

15 . A computing device, comprising:
a plurality of radios operating on a plurality of bands; a memory; and a processor communicatively coupled to the memory, the processor being configured to perform an operation comprising:
determining a device class associated with the computing device;
determining one or more target operating parameters of the computing device, based at least in part on the device class;
determining one or more filter parameters of a plurality of filters for operating the plurality of radios, based at least in part on the one or more target operating parameters; and
configuring the plurality of radios according to the one or more filter parameters.

16 . The computing device of claim 15 , wherein the device class is one of the following types: (i) low power indoor (LPI)-only, standard power (SP)-only, and LPI and SP capable.

17 . The computing device of claim 15 , wherein determining the one or more target operating parameters comprises determining at least one of: (i) a target power budget for the computing device or (ii) a target back-off for each of the plurality of filters, when the device class is low power indoor (LPI)-only.

18 . The computing device of claim 15 , wherein determining the one or more target operating parameters comprises determining at least one of: (i) a target power budget for the computing device, (ii) a channel allowance, or (iii) a Q factor associated with each of the plurality of filters, when the device class is standard power (SP)-only or low power indoor (LPI)-only and SP capable.

19 . The computing device of claim 15 , wherein determining the one or more filter parameters comprises determining a center frequency for each of the plurality of filters.

20 . A non-transitory computer-readable storage medium comprising computer executable code, which when executed by one or more processors, performs an operation comprising:
