Abstract
The system employs full transceivers, each having peer-to-peer, client/server, and IP networking capabilities, and covering open-area ranges of up to 100 feet. The system uses Low Frequency for data communications so it can achieve both low cost (less costly than many RF-ID tags) and long battery life (10-15 years). Additionally, since these tags have batteries, static RAM maybe be added at very low cost, as well as sensors, LED's displays etc.
Claims6
A method for use with a system comprising a plurality of routers, each router in wireless communication with myriad tags, the routers in packet-based communication with each other according to a routing protocol, the method comprising the steps of:
- moving a first tag from a location out of communication with a first router into a location in communication with the first router, said first tag associated with a first IP address, said IP address stored in volatile memory powered by a battery within said first tag;
- establishing the wireless communication between the first tag and the first router, said communication taking place at a frequency below 1 megahertz;
- in response thereto, propagating routing information regarding the tag from the first router to at least one other router;
- at a user location communicatively coupled with the routers, presenting for resolution a human-readable address;
- resolving the human-readable address to the IP address;
- presenting a query at the user location regarding the IP address;
- receiving from the first tag a response thereto;
- and
- rendering information indicative of the response at the user location.

- moving a first tag from a location out of communication with a first router into a location in communication with the first router, said first tag associated with a first IP address and said first tag associated with a first subnet, said IP address and said first subnet stored in volatile memory powered by a battery within said first tag;
- establishing the wireless communication between the first tag and the first router, said communication taking place at a frequency below 1 megahertz;
- in response thereto, propagating routing information regarding the tag from the first router to at least one other router;
- at a user location communicatively coupled with the routers, presenting for resolution a query indicative of the first subnet;
- receiving from the first tag a response thereto;
- and
- rendering information indicative of the response at the user location.
