Communications architecture for a security network
First Claim
1. A communications architecture for a security network containing at least a first and a second base unit and a first transponder, wherein the first transponder communicates to at least the first base unit using low power wireless communications transmitted at average power levels under 10 milliwatts, and the second base unit communicates with the first base unit using high power wireless communications transmitted at average power levels of 10 milliwatts or more.

Abstract
A communications architecture for a security network using low power and high power wireless communications. The low power and high power wireless communications will typically be operating in different frequency bands and at different transmit power levels. The security network contains base units and transponders. Base units may be in the form of cordless phone handsets or cordless phone base stations. Transmissions from a transponder may be received at more than one base unit. A base unit may forward communications from a transponder to another base unit. Transponder communications may contain identifying information and may further encrypt information sent in the communications. Base units may contain data used in determining whether to route communications to another base unit.

21. A communications architecture for a security network containing at least a first and a second base unit and a first transponder, wherein the first transponder communicates to at least the first base unit using intermittent low power wireless communications transmitted at average power levels under 10 milliwatts at a frequency range including 345 MHz, and the second base unit communicates with the first base unit using substantially continuous high power wireless communications transmitted at average power levels of 10 milliwatts or more at a frequency range including 2.4 GHz.

22. A communications architecture for a security network containing at least a first and a second base unit and a first transponder, wherein:
-
the first transponder communicates to at least the first base unit using intermittent low power wireless communications transmitted at average power levels under 10 milliwatts at a frequency range including 345 MHz; the first transponder can receive wireless communications from the first base unit and can change parameters of subsequent transmitted low power wireless communications based upon data received in the wireless communications from the first base unit; the low power wireless communications sent from the first transponder contain identifying information that identifies the first transponder; the second base unit communicates with the first base unit using substantially continuous high power wireless communications transmitted at average power levels of 10 milliwatts or more at a frequency range including 2.4 GHz; and the first base unit can receive a first communication from the first transponder and send a copy of the first communication to the second base unit. - View Dependent Claims (23, 24, 25, 26, 27, 28)
