Abstract
A method can include, by operation of first communication circuits, determining a quality of a plurality of communication frequencies according to wireless communications of a first protocol type; recording a quality of the communication frequencies; selecting communication frequencies for use by second communication circuits based on the quality of the communication frequencies; and wirelessly transmitting and receiving data with the second communication circuits according to a second protocol different than the first protocol; wherein the first and second communication circuits are collocated on the same device. Related devices and systems are also disclosed.
Claims17
A method, comprising:
- by operation of first communication circuits,
- while executing communications across a plurality of first channels that are compatible with a first standard,
- determining a quality of each first channel according to the first standard,
- storing a quality value for each first channel,
- mapping at least first channels having a quality below a predetermined limit to sub-channels of second channels according to a second standard,
- marking one of the sub-channels that maps to at least one first channel having the quality below the predetermined limit as not preferred for use, and
- transmitting data from the first communication circuits that identifies the one sub-channel that is not preferred for use;
- wherein
- the first channels have a different frequency range than the second channels, and
- the second channels are divided into an even number of sub-channels, each having a same sub-channel frequency range.
A device, comprising:
- first communication circuits compatible with at least a first wireless communication standard and including a channel evaluation section configured to evaluate a quality of first channels of the first wireless communication standard based on communications according to the first wireless communication standard;
- control circuits configured to
- while executing communications according to the first wireless standard, determine and store a quality value for each first channel,
- map at least first channels having a quality below a predetermined limit to sub-channels of second channels of a second wireless communication standard,
- mark one of the sub-channels that maps to at least one first channel having the quality below the predetermined limit as not preferred for use, and
- communicate data that identifies the sub-channel that is marked as not preferred for use, wherein
- the first channels have a different frequency range than the second channels, and
- the second channels are divided into an even number of sub-channels, each having a same sub-channel frequency range.
A system, comprising:
- at least a first device having
- first communication circuits configured to evaluate a quality of first wireless channels based on communications by the first communication circuits according to a first standard,
- control circuits configured to
- while executing communications according to the first standard, determine and store a quality value for each first wireless channel,
- map at least first wireless channels having a quality below a predetermined limit to sub-channels of second wireless channels of a second wireless standard,
- mark one of the sub-channels that maps to at least one first wireless channels having the quality below the predetermined limit as not preferred for use, and
- communicate data that identifies the one sub-channel that is marked not preferred for use;
- wherein
- the first wireless channels have a different frequency range than the second wireless channels,
- the second channels are divided into an even number of sub-channels, each having a same sub-channel frequency range, and
- the first and second standards indicate operations in a same band.
