Abstract
Techniques for guard band usage for wireless data transmission are described. In at least some embodiments, white spaces in the radio spectrum (e.g., television (TV) white spaces) and guard bands between licensed bands of the radio spectrum are leveraged for data transmission. Based on available white spaces and service deployment in the licensed bands, various decisions can be made regarding how to leverage white spaces and guard bands for wireless data transmission.
Claims20
A system comprising:
- one or more processors;
- and
- one or more computer-readable storage media storing computer-executable instructions that are executable by the one or more processors to perform operations including:
- ascertaining available white spaces in a region of the radio spectrum;
- determining whether there is service deployment in a licensed band adjacent to a guard band in the region, said determining including determining that there is not infrastructure in place for deployment of service in the licensed band;
- and
- providing a notification of identifiers for the available white spaces and an indication that there is not infrastructure in place for service deployment in the licensed band to enable a client device to utilize the guard band and one or more of the white spaces for wireless data transmission.
4 more elements
A method comprising:
- ascertaining an available white space in a region of the radio spectrum;
- determining whether there is service deployment in a licensed band adjacent to a guard band in the region, said determining including determining that there is not infrastructure in place for deployment of service in the licensed band;
- and
- providing a notification of an identifier for the available white space and an indication that there is not infrastructure in place for service deployment in the licensed band to enable a client device to utilize the guard band and the white space for wireless data transmission.
1 more element
A method comprising:
- receiving a query from a client device for an available wireless channel in a particular geographical region;
- ascertaining an available white space in the particular geographical region;
- determining whether there is service deployment in a licensed band adjacent to a guard band in a particular portion of radio spectrum in which the available white space resides, said determining including determining there is not infrastructure in place for deployment of service in the licensed band;
- and
- providing a notification of an identifier for the available white space and an indication that there is not infrastructure in place for service deployment in the licensed band to enable a client device to utilize the guard band and the white space for wireless data transmission.
