Abstract
An RFID security network using system component diversity and system spatial diversity is disclosed. The security network includes a plurality of network base units, each communicating with a plurality of transponders, or security transmitters. Through appropriate distributive placement of the plurality of base units, along with appropriate placement of the transponders, the redundancy and reliability of the RF communication links between one or more base units and one or more transponders is increased. Moreover, because each of the base units is capable of being a communications gateway with an external network, including a telecommunications network, the security network's access to an outside telecommunications network is redundant and highly reliable. Accordingly, even if an intruder attempts to disable the security system communications to an external network, the inventive security network has redundant and alternative communication links to an external network. Such component and spatial diversity substantially enhances the security network's reliability.
