Abstract

A method of managing the radio frequency environment of a building zone includes using a plurality of radio frequency enabled building management devices distributed around the building zone. The method also includes interrupting a radio frequency enabled building management device from the device'"'"'s primary building management function when a measuring event occurs, measuring radio frequency information of the building zone using the interrupted radio frequency enabled building management device, sending the measured radio frequency information from the radio frequency enabled building management device to a controller system, storing the measured radio frequency information in a database of the controller system. The method also includes repeating the interrupting, measuring, sending, and storing steps for a plurality of radio frequency enabled building management devices.

Claims

1. A method of managing the radio frequency environment of a building zone using a plurality of radio frequency enabled building management devices distributed around the building zone, comprising:

interrupting a radio frequency enabled building management device from the device'"'"'s primary building management function when a measuring event occurs;

measuring radio frequency information of the building zone using the interrupted radio frequency enabled building management device;

sending the measured radio frequency information from the radio frequency enabled building management device to a controller system;

storing the measured radio frequency information in a database of the controller system; and

repeating the interrupting, measuring, sending, and storing steps for a plurality of radio frequency enabled building management devices.

2. The method of claim 1, further comprising suggesting operating parameters to a user for two different wireless systems located in or around the building zone based on the measured radio frequency information.

3. The method of claim 1, further comprising alerting a user when a potential conflict between two different wireless systems is detected.

4. The method of claim 3, further comprising recommending a course of action to a user regarding configuration of the two different wireless systems.

5. The method of claim 1, further comprising displaying a map of radio frequency energy in or around the building zone.

6. The method of claim 5, wherein the map is a graphical user interface map.

7. The method of claim 1, further comprising displaying the measured radio frequency information to a user.

8. The method of claim 1, further comprising processing the radio frequency information to create a report of the radio frequency environment of the building zone.

9. The method of claim 1, further comprising defining radio frequency ranges or channel ranges in or around the building zone based on the measured radio frequency information.

10. The method of claim 9, further comprising presenting the defined ranges to a user.

11. The method of claim 9, further comprising using the defined ranges to suggest operating parameters for a wireless system.

12. The method of claim 9, further comprising using the defined ranges to suggest operating parameters for at least two wireless systems.

13. The method of claim 9, further comprising developing an action strategy based upon the defined ranges.

14. The method of claim 1, further comprising displaying a graph of the measured radio frequency information.

15. The method of claim 1, further comprising developing a list of alternative channels for a wireless system.

16. The method of claim 1, further comprising scheduling a channel switch based on the measured radio frequency information.

17. The method of claim 1, wherein measuring radio frequency information of a building zone using the radio frequency enabled building management device includes measuring over a frequency range greater than the operating range of the device when the device is operating in its primary building management function.

18. A distributed spectrum analyzer for a building automation system comprising:

a plurality of radio frequency enabled building management devices distributed around a building zone, each of the plurality of devices capable of measuring radio frequency information in the building zone; and

a controller system configured to collect and analyze the measured radio frequency information, wherein the controller system maintains a database of collected measured radio frequency information.

19. The system of claim 18, wherein the controller system is further configured to generate a graphical user interface map based on the database of collected measured radio frequency information.

20. The system of claim 18, wherein the controller system is further configured to generate a report containing radio frequency information about at least two different wireless systems.
