1. A system comprising:
- one or more processors; and
one or more computer-readable storage devices storing computer-executable instructions that are executable by the one or more processors to perform operations including;
utilizing at least a portion of a guard band as a wireless channel for wireless data communication;
utilizing a different portion of the guard band for mitigating interference between the wireless data communication in the wireless channel and signal activity in a different wireless channel that is adjacent to the guard band;
detecting signal activity in the different wireless channel;
detecting data errors in relation to the wireless data communication over the wireless channel;
comparing the data errors to a data error threshold; and
reducing a width of the wireless channel within the guard band used for the wireless data communication responsive to ascertaining that the detected data errors exceed the data error threshold.

Abstract
Techniques for guard band utilization for wireless data communication are described. In at least some embodiments, guard bands can be leveraged to transmit wireless broadband data and/or other forms of wireless data. According to one or more embodiments, signal activity in a wireless channel that is adjacent to a guard band is monitored, e.g., while the guard band is being utilized for wireless data communication. In at least some implementations, if the signal activity exceeds a signal activity threshold, usage of the guard band channel can be adjusted to mitigate interference with signal activity in an adjacent channel.

17. A computer-implemented method comprising:
-
identifying a pre-specified portion of radio spectrum that corresponds to a guard band; specifying, within the pre-specified portion that corresponds to the guard band, a wireless channel portion for wireless data communication and an interference mitigation portion, the interference mitigation portion being usable for mitigating interference between the wireless data communication in the wireless channel portion and signal activity in a different wireless channel that is adjacent to the guard band; utilizing the wireless channel portion of the guard band as a wireless channel for the wireless data communication; detecting signal activity in the different wireless channel adjacent to the guard band; detecting data errors in the wireless data communication over the wireless channel portion of the guard band; comparing, by a computing device, the data errors to a data error threshold; and reducing, by the computing device, a width of the wireless channel portion within the guard band responsive to ascertaining that the detected data errors exceed the data error threshold. - View Dependent Claims (18, 19, 20)
