Authentication codes for building/area code address
View Patent ↗A low cost, robust, wireless sensor that provides an extended period of operability without maintenance is described. The wireless sensors are configured to communicate with a base unit or repeater. When the sensor unit detects an anomalous ambient condition (e.g., smoke, fire, water, etc.) the sensor communicates with the base unit and provides data regarding the anomalous condition. The sensor unit receives instructions to change operating parameters and/or control external devices.
1. A method of bi-directional communication within a wireless sensor system using authentication codes, comprising:
communicating with each of one or more wireless sensor units to and from a base unit via, at least one of, one or more wireless repeater units using communication packets having at least a first building/area code address and a sub-code address;
waiting for a programmed delay by each of said one or more wireless repeater units after receiving said communication packets having at least a first building/area code address and a sub-code address;
forwarding said communication packets from said one or more wireless sensor units to said base unit by said one or more wireless repeater units;
forwarding said communication packets from said base unit to said one or more wireless sensor units by said one or more wireless repeater units to the building/area within said wireless sensor system assigned to said first building/area code address in said communication packets; and
receiving said forwarded communication packets in said building/area within said wireless system by each of said one or more wireless sensor units assigned to both said first building/area code address and said sub-code address in said communication packets.
2. A method of bi-directional communication with a wireless sensor unit using authentication codes, comprising:
communicating with said wireless sensor unit using communication packets having at least a first building/area code address and a sub-code address;
waiting for a programmed delay after receiving communication packets to or from said wireless sensor unit;
forwarding said communication packets from wireless sensor unit; and
forwarding said communication packets to the building/area assigned to said first building/area code address in said communication packets and receiving said forwarded communication packets by said wireless sensor unit assigned to both said first building/area code address and said sub-code address in said communication packets.
3. The method of claim 2 , wherein the programmed delay is randomly chosen.
4. The method of claim 2 , wherein the programmed delay is randomly chosen for each communication packet.
5. The method of claim 2 , wherein the first building/area code address is at least 6 digits.
6. The method of claim 2 , wherein the sub-code address is at least 5 digits.
7. A method comprising:
communicating with a wireless sensor unit using communication packets having at least a first code and a second code;
waiting for a programmed delay after receiving communication packets to or from said wireless sensor unit;
forwarding said communication packets from said wireless sensor unit; and
forwarding said communication packets to the location assigned to said first code in said communication packets and receiving said forwarded communication packets by said wireless sensor unit assigned to both said first code and said second code in said communication packets.
8. The method of claim 7 , wherein the location is a building.
9. The method of claim 7 , wherein the programmed delay is randomly chosen.
10. The method of claim 7 , wherein the programmed delay is randomly chosen for each communication packet.
11. The method of claim 7 , wherein the first code is at least 6 digits.
12. The method of claim 7 , wherein the second code is at least 5 digits.
13. The method of claim 1 , wherein the programmed delay is randomly chosen.
14. The method of claim 1 , wherein the programmed delay is randomly chosen for each communication packet.
15. The method of claim 1 , wherein the first building/area code address is at least 6 digits.
16. The method of claim 1 , wherein the sub-code address is at least 5 digits.
