ASSET LOCATION USING RELAYS
First Claim
1. A method for asset location via a relay tag, the method comprising:
- receiving, at the relay tag, an asset message from an asset tag according to a wireless communication protocol, wherein the relay tag has a known location;
producing, at the relay tag, a relay message using information contained in the asset message, wherein the relay message includes an indication of the relay tag from which the relay message is sent and an indication of the asset tag from which the asset message was received; and
sending the relay message from the relay tag to a receiver using the wireless communication protocol.

16. An asset location system comprising:
-
an asset tag configured to be attached to an asset and to transmit an asset message according to a wireless communication protocol; a plurality of relay tags, each of the plurality of relay tags configured to receive the asset message from the asset tag, to determine a received signal strength indication (RSSI) for the asset message, to generate a relay message including an indication of the relay tag, an indication of the asset tag, and the RSSI, and to transmit the relay message; a receiver configured to receive the relay messages from the plurality of relay tags, to generate a receiver message including content of the relay messages, and to transmit the receiver message; and a server configured to receive the receiver message from the receiver and to determine a location of the asset tag using content of the receiver message. - View Dependent Claims (17, 18, 19, 20)
