Abstract:
1. An asset tracking system, comprising: a plurality of transmitting points, the transmitting points each having a MAC address header, the MAC address header including an organizational unique identifier indicating status as a transmitting point as opposed to an access point, the transmitting points operating in a frequency range associated with an 802.11 standard and not being an 802.11 access point; and a tag unit configured to communicate with the plurality of transmitting points and a plurality of access points and configured to distinguish between the access points and the transmitting points using the organizational unique identifier, the tag unit configured to receive RF signals from the transmitting points and the access points, wherein a positioning station is configured to receive data associated with signal strengths of the RF signals, wherein the data is analyzed to determine a location of the tag unit, wherein position is determined by comparing the data to stored signal strengths associated with particular locations, wherein the tag unit is configured to provide the data to the positioning station via an access point of the access points associated with the strongest signal strength in the data, wherein the tag unit includes a motion detector, wherein the tag unit is powered down when stationary.
