Abstract
A method of operating a spectrum system includes issuing commands to a transmitter in communication with the spectrum system, receiving network measurements from one or more wireless terminals, comparing, using a computing processor, the network measurements with the issued commands, and determining a compliance of the transmitter to the issued commands.
Claims38
A method of operating a spectrum system, the method comprising:
- issuing commands to a transmitter in communication with the spectrum system;
- receiving network measurements from one or more wireless terminals;
- comparing, using a computing processor, the network measurements with the issued commands;
- determining a compliance of the transmitter to the issued commands;
- communicating transmitter commands to a spectrum operator system, the spectrum operator system in communication with the transmitter;
- and
- instructing the spectrum operator system to:
- identify a set of wireless terminals associated with the transmitter;
- instruct the set of wireless terminals or a subset of the wireless terminals associated with the transmitter to return network measurements to the spectrum system;
- and
- instruct different subsets of wireless terminals associated with the transmitter over time to return network measurements to the spectrum system.
