Abstract

Devices, systems and methods track geographical locations of a wireless device and time associated with the wireless device. Embodiments access channel map data including a predicted channel condition value for each of multiple communication channels within each of a plurality of geographical locations during a plurality of time periods of day. Embodiments use the channel map data to select one of the multiple communication channels for communication in a second geographical location, based on a first geographical location of the wireless device and a time of day associated with the wireless device.

First claim

What is claimed is:

1. A method of a wireless device, comprising:
tracking geographical locations of the wireless device and time associated with the wireless device;
accessing channel map data comprising a predicted channel condition value for each of a plurality of communication channels within each of a plurality of geographical locations during a plurality of time periods of day; and
using the channel map data, selecting one of the plurality of communication channels for communication in a second geographical location, based on a first geographical location of the wireless device and a time of day associated with the wireless device, wherein the selecting the one of the plurality of communication channels is initiated prior to entering the second geographical location.

2. The method of claim 1 , wherein the accessing of the channel map data comprises receiving the channel map data from a remote computer, wherein the channel map data is based on channel condition data crowd sourced by a plurality of devices.

3. The method of claim 1 further comprising:
detecting channel condition data associated with at least one of the plurality of communication channels, within at least one of the plurality of geographical locations, during at least one of the plurality of time periods of day; and
providing the detected channel condition data for a generation of the channel map data or a generation of updated channel map data.

4. The method of claim 3 , wherein the detecting of the channel condition data associated with the at least one of the plurality of the communication channels comprises detecting at least one of a received signal strength indicator, a signal-to-noise ratio value, a transmit opportunity value, and a packet loss value.

5. The method of claim 3 , wherein the detecting of the channel condition data comprises detecting channel condition data reflecting channel utilization that is not in compliance with a communication protocol.

6. The method of claim 1 , further comprising determining a speed of the wireless device, wherein the selecting of the one of the plurality of communication channels for communication is initiated based on the determined speed.

7. The method of claim 1 , wherein the accessing of the channel map data comprises determining that a condition value of a first channel currently being used for communication meets or exceeds a threshold condition level and accessing the channel map data responsive to the determination.

8. The method of claim 1 , wherein the selecting of the one of the plurality of communication channels comprises selecting the one of the plurality of communication channels for communication in an automotive network including the wireless device and at least one other wireless device.

9. The method of claim 1 , wherein the selecting of the one of the plurality of communication channels comprises:
using the channel map data, determining that a first predicted condition value of a first communication channel within the second geographical location during a first time period of day is greater than a second predicted condition value of a second communication channel within the second geographical location during the first time period of day; and
responsive to the determination, switching from using the first communication channel for communication to using a second communication channel for communication.

10. The method of claim 9 , wherein the determining that the first predicted condition value of the first communication channel is greater than the second predicted condition value of the second communication channel comprises determining that the second predicted condition value is less than a threshold condition level.

11. The method of claim 6 , wherein the selecting the one of the plurality of communication channels for communication comprises adjusting a transmit power used to transmit data via the selected one of the plurality of communication channels.

12. The method of claim 6 , wherein the selecting the one of the plurality of communication channels for communication comprises switching from using a first communication channel width for communication to using a second communication channel width for communication.

13. A wireless device, comprising:
one or more processing devices; and
a memory system configured to store instructions and channel map data, the channel map data comprising a predicted congestion value for each of a plurality of communication channels within each of a plurality of geographical locations during a plurality of time periods of day, wherein the one or more processing devices is configured to process the instructions to cause the wireless device to:
track geographical locations of the wireless device, track time associated with the wireless device, and use the channel map data stored in the memory system to, prior to entry by the wireless device into a second geographical location from a first geographical location, select one of the plurality of communication channels for communication, based on a geographical location of the wireless device and a time of day associated with the wireless device.

14. The wireless device of claim 13 , wherein the one or more processing devices is configured to process the instructions to cause the wireless device to select, based on at least one predicted congestion value, the one of the plurality of communication channels for communication.

15. The wireless device of claim 13 , wherein each predicted congestion value is based on at least one of a received signal strength indicator, a signal-to-noise ratio value, a transmit opportunity value, and a packet loss value.

16. The wireless device of claim 13 , wherein the one or more processing devices is configured to process the instructions to cause the wireless device to determine that a first predicted condition value of a first communication channel within the second geographical location during a first time period of day is greater than a second predicted congestion value of a second communication channel within the second geographical location during the first time period of day, and responsive to the determination, switch the wireless device from using the first communication channel for communication to using a second communication channel for communication.

17. The wireless device of claim 13 , wherein the one or more processing devices is configured to process the instructions to cause the wireless device to switch from using a first communication channel width for communication to using a second communication channel width for communication.

18. The wireless device of claim 13 , wherein the one or more processing devices is configured to process the instructions to cause the wireless device to adjust a transmit power used to transmit data via the selected one of the plurality of communication channels.

19. A vehicle infotainment system comprising:
an antenna;
one or more processing devices; and
a memory system configured to store instructions and channel map data, the channel map data comprising a predicted congestion value for each of a plurality of communication channels within each of a plurality of geographical locations during a plurality of time periods of day, wherein the one or more processing devices is configured to process the instructions to cause the vehicle infotainment system to:
track geographical locations of the vehicle infotainment system, track time associated with the vehicle infotainment system, and use the channel map data stored in the memory system to, pr
