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.
Claims21
A method, comprising:
- by operation of first communication circuits, determining a quality of a plurality of communication frequencies according to data received via wireless communications of a first protocol,
- selecting the communication frequencies having a higher quality over those having a lower quality for use by communications according to the first protocol;
- recording a quality of the communication frequencies;
- selecting sub-channels of a channel having communication frequencies of the higher quality over sub-channels of the channel having communication frequencies of the lower quality for use by second communication circuits for transmitting and receiving data according to a second protocol;
- and
- wirelessly transmitting and receiving data with the second communication circuits according to the second protocol different than the first protocol;
- wherein
- the first and second communication circuits are collocated on the same device, and
- the second communication protocol includes transmissions over the channel and transmissions over sub-channels, each sub-channel occupying no more than half a frequency range of the channel.
A device, comprising:
- first communication circuits configured to
- wirelessly receive and transmit data according to a first protocol and maintain a quality indication of frequencies used by communications according to the first protocol, and
- select higher quality frequencies over lower quality frequencies for use in communications according to the first protocol;
- and
- second communication circuits configured to wirelessly receive and transmit data according to a second protocol different than the first protocol and select sub-channels of a channel having the higher quality frequencies over sub-channels of the channel having the lower quality frequencies for bi-directional communications according to the second protocol;
- wherein
- the first communication circuits acquire the quality indications of the frequencies while the second communication circuits are not receiving or transmitting data, and
- the second communication protocol includes transmissions over the channel and transmissions over sub-channels, each sub-channel occupying no more than half a frequency range of the channel.
A system, comprising:
- a combination device that includes
- first communication circuits configured to
- wirelessly receive and transmit data according to a first protocol and maintain a quality indication of frequencies used by communications according to the first protocol, and
- select higher quality frequencies over lower quality frequencies for use in communications according to the first protocol;
- and
- second communication circuits configured to wirelessly receive and transmit data according to a second protocol different than the first protocol and select sub-channels of a channel having the higher quality frequencies over sub-channels of the channel having the lower quality frequencies for use in bi-directional communications according to the second protocol;
- and
- at least a second device in communication with the combination device according to at least the first protocol, and
- the second communication protocol includes transmissions over the channel and transmissions over sub-channels, each sub-channel occupying no more than half a frequency range of the channel.
