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.
