Abstract

A method for optimizing RF coverage includes dividing a floor plan according to a plurality of grids. Radio frequency coverage for each of the plurality of grids is calculated to render a plurality of coverages. First data representative of the plurality of coverage grids is provided to a client. Second data representative of an incremental change in radio frequency coverage for a first grid of the plurality of grids is provided to the client.

Claims (34)

1. A method for optimizing radio frequency (RF) coverage, comprising:

dividing a floor plan of a building according to a plurality of grids based upon a plurality of geographical separation lines dependent on a physical or environmental factor associated with the building;

calculating radio frequency coverage for each of the plurality of grids to render a plurality of coverages;

combining, if a difference in signal strength associated with a first and second of the plurality of grids is within a predetermined threshold, the first and second grid into a combined grid;

providing first data representative of the plurality of coverages to a client;

monitoring the plurality of grids for a change in signal strength; and

providing, when the change in signal strength is detected, second data representative of an incremental change in the radio frequency coverage for a first grid of the plurality of grids to the client.

2. The method of claim 1 , further including detecting the incremental change in radio frequency coverage for the first grid by processing changes in signal strength data received by a server from a mobile device.

3. The method of claim 2 , further including calculating an updated radio frequency coverage for the first grid based on the changes in signal strength data.

4. The method of claim 3 , further including providing third data representative of an incremental change in radio frequency coverage for the second grid of the plurality of grids to the client.

5. The method of claim 1 , wherein the floor plan is a site floor plan, the site floor plan including at least two buildings.

6. The method of claim 1 , wherein providing second data representative of an incremental change in radio frequency coverage is performed subject to a request by the client.

7. A system for optimizing displayed radio frequency (RF) coverage, comprising:

means for dividing a floor plan of a building according to a plurality of grids based upon a plurality of geographical separation lines dependent on a physical or environmental factor associated with the building;

means for calculating radio frequency coverage for each of the plurality of grids to render a plurality of coverages;

means for combining, if a difference in signal strength associated with a first and second of the plurality of grids is within a predetermined threshold, the first and second grid into a combined grid;

means for providing first data representative of the plurality of coverages to a client; and

means for monitoring the plurality of grids for a change in signal strength; and

means for providing, when the change in signal strength is detected, second data representative of an incremental change in the radio frequency coverage for a first grid of the plurality of grids to the client.

8. The system of claim 7 , further including means for detecting the incremental change in radio frequency coverage for the first grid by processing changes in signal strength data received by a server from a mobile device.

9. The system of claim 8 , further including means for calculating an updated radio frequency coverage for the first grid based on the changes in signal strength data.

10. The system of claim 9 , further including means for providing third data representative of an incremental change in radio frequency coverage for the second grid of the plurality of grids to the client.

11. The system of claim 7 , wherein the floor plan is a site floor plan, the site floor plan including at least two buildings.

12. The system of claim 7 , wherein the second data representative of an incremental change in radio frequency coverage is provided subject to a request by the client.

13. A computer program product, comprising: a non-transitory computer-usable medium having computer-readable code embodied therein for displaying radio frequency (RF) coverage information, the computer program product comprising:

a first executable computer-readable code configured to cause a computer processor to divide a floor plan of a building according to a plurality of grids based upon a plurality of geographical separation lines dependent on a physical or environmental factor associated with the building;

a second executable computer-readable code configured to cause the computer processor to calculate radio frequency coverage for each of the plurality of grids to render a plurality of coverages and to combine, if a difference in signal strength associated with a first and second grids of the plurality of grids is within a predetermined threshold, the first and second grids into a combined grid;

a third executable computer-readable code configured to cause the computer processor to provide first data representative of the plurality of coverages to a client; and

a fourth executable computer-readable code configured to monitor the plurality of grids for a change in signal strength and to cause the computer processor to provide, when the change in signal strength is detected, second data representative of an incremental change in the radio frequency coverage for the plurality of grids to the client.

14. The computer program product of claim 13 , further including a fifth executable computer-readable code configured to cause the computer processor to detect the incremental change in radio frequency coverage for the first grid by processing changes in signal strength data received by a server from a mobile device.

15. The computer program product of claim 14 , further including a sixth executable computer-readable code configured to cause the computer processor to calculate an updated radio frequency coverage for the first grid based on the changes in signal strength data.

16. The computer program product of claim 15 , further including a seventh executable computer-readable code configured to cause the computer processor to provide third data representative of an incremental change in radio frequency coverage for the second grid of the plurality of grids to the client.

17. The computer program product of claim 13 , wherein the floor plan is a site floor plan, the site floor plan including at least two buildings.

18. The computer program product of claim 13 , the second data representative of an incremental change in radio frequency coverage is provided subject to a request by the client.
