Abstract
An asset tracking system includes a station, transmitting points, and an asset tag. The asset tag can be used for communicating with the transmitting points to form a mesh network. The station receives data associated with signal strengths between transmitting points and asset tag. The station analyzes the data associated with a number of the transmitting points and determines the location of the asset tag.
Claims20
An asset tracking system, comprising:
- a station;
- a plurality of transmitting points each being at a respective fixed, known location;
- and
- at least one asset tag for communicating with the plurality of transmitting points, the station receiving data associated with signal strengths between the plurality of transmitting points and the at least one asset tag, the asset tag providing the data associated with the signal strengths between the transmitting points and the asset tag, wherein the station analyzes the data associated with signal strengths from the plurality of the transmitting points and determines a location of the at least one asset tag.
1 more element
A method of tracking an asset, the method comprising:
- receiving a transmission at an asset tag from at least one transmitting point of a plurality of transmitting points, each transmitting point being at a respective fixed, known location wherein the asset tag is affixed to an asset to be tracked;
- collecting data associated with a signal strength of the transmission;
- and
- transmitting the collected data from the asset tag for eventual reception by a station, wherein the station analyzes the collected data and determines a location of the asset tag affixed to the asset to be tracked.
