Abstract
A system and method for managing wireless communication over an area using solar-powered radio transceivers. A processor selects an optimal transceiver to communicate with nodes in the area based on historical link quality strength of previous nodes in the same area. Different power reduction techniques are employed for non-selected transceivers, including turning them off or reducing power consumption.
Claims28
A method of operating a processor to remotely control the power use of two or more fixed location radio transceivers, the control being dependent on the location of one or more movable nodes located in an area, the method comprising:
- populating a geo-spatial database with link quality data associated with the one or more historical nodes as received by each transceiver over a period of time, by the steps of:
- a. instructing all transceivers to receive one or more uplinks from the one or more historical nodes, the uplinks comprising at least historical node location data;
- b. instructing the one or more historical nodes to send periodic uplinks;
- c. measuring link quality of one or more uplinks;
- d. associating each node location with a geo-index of the geo-spatial database;
- and
- e. assigning the link quality data and associated transceiver to said geo-index;
- and
- receiving an uplink from nodes and determining their current location from said uplink and their associated geo-index, the nodes being the same or different to the historical nodes whose link quality was measured;
- identifying associated transceivers with link quality data above a threshold for each associated geo-index;
- determining a selection of the one or more said identified associated transceivers based on one or more predefined selection criteria;
- and
- reducing power to, or consumption of power by, all other transceivers except the one or more selected transceivers.

A system for controlling power usage of radio devices comprising:
- one or more moveable nodes, each node comprising:
- a sensor configured to determine location data, and
- a transmitter configured to transmit location data by radio uplinks;
- two or more fixed location radio transceiver devices, each device comprising a radio component configured to receive uplinks and output transceiver data comprising link quality data and node location data;
- and
- a processor configured to:
- receive transceiver data,
- populate a geo-spatial database with received transceiver data including geo-indices of transceiver data based on the node location data, and
- control one of two or more power consumption modes of one or more radio transceiver devices based on:
- node location data,
- a determined geo-index, and
- one or more predefined selection criteria.
