Embodiment Construction

[0018] Overview

[0019] Describes the technology used in the guard band for wireless data communication. In at least some embodiments, white space in the radio spectrum (eg, television (TV) white space) and a guard band between licensed portions of the radio spectrum are used for data transmission.

[0020] For example, the embodiment adopts a channel database, which tracks available white space and notifies each wireless base station and / or client device of the available white space. The channel database may also notify the wireless base station and / or the client device of whether there is a service deployment in the licensed band that appears adjacent to the guard band in the radio frequency spectrum. Based on the available white space and the service deployment in the licensed band, various decisions can be made on how to use the white space and guard band for wireless data transmission.

[0021] In at least some embodiments, white space and / or guard bands can be used to trans...

Abstract

Describes techniques used in guard bands for wireless data transmission. In at least some embodiments, white space in the radio spectrum (eg, television (TV) white space) and guard bands between licensed bands of the radio spectrum are used for data transmission. Based on the available white space and the deployment of services in the licensed band, various decisions can be made on how to utilize the white space and guard band for wireless data transmission.

Description

Background technique [0001] Many devices currently use some form of radio frequency (RF) data communication. Examples of RF communications include cellular networks (e.g., for cell phones), data broadband (e.g., ), radio and television, global positioning system (GPS) navigation, etc. Typically, different forms of RF communication use different parts of the radio spectrum. Although many parts of the radio spectrum are allocated and / or licensed for specific purposes, there are still underused parts. The underused portion of the radio spectrum can be used for various purposes, such as for unlicensed form of RF communication. However, any use of these underused parts must avoid interfering with existing licensed RF communications and must comply with RF communications specifications. Summary of the invention [0002] The content of the present invention is provided in order to introduce the selection of ideas in a simplified form further described in the detailed description bel...
