CONFIGURING A NETWORK OF DEVICES TO OPERATE WITHIN A TELEVISION WHITESPACE SPECTRUM
First Claim
1. A computer-implemented method for configuring a node to communicate on a television white space (TVWS) spectrum of frequencies, the method comprising:
- receiving a request for at least one operating parameter from a first node that resides at a first location in a network;
retrieving one or more entries associated with the first location from a first database, wherein each of the one or more entries reflects a quality of service metric for a TVWS channel at the first location;
determining the at least one operating parameter for the first node based on the one or more entries, wherein the at least one operating parameter indicates a first TVWS channel; and
transmitting the at least one operating parameter to the first node, wherein the first node is configured to perform future communication operations over the first TVWS channel according to the at least one operating parameter.

Abstract
Nodes within a network are configured to communicate with one another on one or more television white space (TVWS) frequencies that may be subject to interference caused by nearby TV towers. In order to mitigate that interference, the nodes may be configured to communicate according to specific operating parameters. The operating parameters may be generated based on expected interference levels caused by the nearby TV towers or QOS metrics associated with available channels. The nodes may also update a private database to reflect the expected interference levels or measured QOS metrics for different channels.

21. A computer-implemented method for configuring a node to communicate on a television white space (TVWS) spectrum of frequencies, the method comprising:
-
receiving a request for a first TVWS channel from a first node that resides at a first location in a network; retrieving one or more entries associated with the first location from a first database, wherein a given entry included in the one or more entries reflects a quality of service metric associated with a given TVWS channel computed by a given node residing at the first location and configured to communicate on the given TVWS channel; determining the first TVWS channel for the first node based on the quality of service metrics associated with the one or more entries; and transmitting the first TVWS channel to the first node, wherein the first node is configured to perform a communication operation over the first TVWS channel. - View Dependent Claims (22)
