Communications architecture for a security network
View Patent ↗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.
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.

7. The communications architecture in claim 6 wherein the first transponder can change parameters of subsequent transmitted low power wireless communications based upon data received in the wireless communications from the first base unit.
8. The communications architecture in claim 1 wherein 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.
9. The communications architecture in claim 1 wherein the low power wireless communications sent from the first transponder contain identifying information that identifies the first transponder.
10. The communications architecture in claim 1 wherein the low power wireless communications sent from the first transponder contain identifying information that identifies the security network in which the first transponder is enrolled.
11. The communications architecture in claim 1 wherein at least part of the low power wireless communications sent from the first transponder has been encrypted using an encryption key.
12. The communications architecture in claim 1 wherein the low power wireless communications sent from the first transponder to the first base unit are received by the second base unit.
13. The communications architecture in claim 9 wherein the first base unit contains first data used by the first base unit to determine whether to send a copy of the low power wireless communications sent from the first transponder to the second base unit.
14. The communications architecture in claim 13 wherein the first data include identifying information about the first transponder.
15. The communications architecture in claim 11 wherein the first base unit contains an encryption key than enables the first base unit to interpret the low power wireless communications sent by the first transponder to the first base unit.
16. The communications architecture in claim 1 wherein the first base unit is in the physical form of a cordless phone handset.
17. The communications architecture in claim 1 wherein the second base unit is in the physical form of a cordless phone handset.
18. The communications architecture in claim 1 wherein the second base unit is in the physical form of a cordless phone base station.
19. The communications architecture in claim 1 wherein the first base unit is powered by a battery.
20. The communications architecture in claim 12 wherein the second base unit sends a copy of the low power wireless communications sent from the first transponder to the first base unit using high power wireless communications.
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;
