SYSTEMS AND ETIQUETTE FOR HOME GATWAYS USING WHITE SPACE
First Claim
1. A system for redistributing data signals to wireless enabled devices located within a specified area, comprising:
- a spectrum detector for identifying a white space channel including one or more pieces of spectrum that are not currently used in the specified area;
a data distribution unit adapted to receive, process and distribute to devices it serves, information signals received from a variety of sources over the white space channel; and
a control channel processor for providing a shared signalling channel for enabling signalling between the wireless enabled device and the data distribution unit.

Abstract
Methods and systems for sharing white space with primary services and other emerging services are provided. Signal distribution within a specified location, such as a dwelling, is performed using a home gateway that identifies unused white space, reserves such white space spectrum, and delivers data to one or more devices at the respective location using the reserved spectrum. Signalling between the devices and the gateway is performed over a shared signalling channel, which enables the gateway to advise the devices from where and when to receive data. The gateway also uses a common spectrum reservation OFDM symbol to advise the neighbouring gateways of the local spectrum reservation.

26. A method for redistributing data signals from a gateway to wireless enabled devices located within a specified area, comprising:
-
a) establishing, on start on, a shared signalling channel over a piece of spectrum that is not currently used in the specified area; b) on receipt of a service request from a device transmitted over the shared signalling channel, establishing a white space channel using one or more pieces of spectrum that are not currently used in the specified area; c) distributing an information signal over the white space channel to the device; and d) controlling transfer of the information signal to the device by exchanging control messages over the shared signalling channel. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)

35. A method for redistributing data signals to wireless enabled devices located within a specified area served by a gateway, comprising:
-
a) on receipt of service requests from one or more devices, identifying a corresponding number of white space channels within the spectrum that is not currently used in the specified area; b) reserving the white space allocated to the white space channels identified in the specified area; c) broadcasting a white space allocation message for advertising to all neighbouring gateways the current channel allocation in the specified area; and d) distributing the information signals over the white space channels to the respective devices. - View Dependent Claims (36, 37, 38, 39, 40)
