Abstract

At least one example disclosed herein relates to determining if a change to a wireless network configuration should be determined. If it is determined that the change to the wireless network should be determined, a plurality of coverage monitors are generated within a site model, each coverage monitor specifying at least one coverage parameter for an associated region of the site model. The change to the wireless network may be determined by identifying a change to a configuration of a wireless access point.

1. A non-transitory machine-readable storage medium, storing instructions which, when executed by a processor of a computing device, cause the computer device to:

determine if a change to a wireless network configuration should be determined;

if it is determined that the change to the wireless network configuration should be determined,

generate a plurality of coverage monitors within a site model, each coverage monitor specifying at least one coverage parameter for an associated region of the site model;

determine the change to the wireless network configuration by;

iteratively adjust at least one wireless access point (WAP) setting value to generate at least one first trial WAP configuration; and

iteratively adjust at least one WAP position value to generate at least one second trial WAP configuration if, for each first trial WAP configuration, a respective first coverage prediction fails to satisfy at least one of the coverage parameters;

determine an alteration to a number of WAPs if, for each second trial WAP configuration, a second coverage prediction fails to satisfy at least one of the coverage parameters;

identify the alteration as part of the change to the wireless network configuration;

provide the change to the wireless network configuration to a display device; and

modify the wireless network configuration based on the change, upon receipt of a user authorization of the alteration.

2. The non-transitory machine-readable storage medium of claim 1, further including instructions to:

access, with the processor, a historical information related to access point usage within the wireless network configuration to determine if a misusage event occurred;

analyze the historical information of a WAP within the wireless network configuration to determine if a number of misusage events in a predetermined time interval is outside a predetermined range of acceptable misusage events; and

determine that the change to the wireless network configuration should be determined when the number of misusage events within the predetermined time interval is outside the predetermined range of acceptable misusage events.

3. The non-transitory machine-readable storage medium of claim 2, further including instructions to:

identify at least one client device that are within a predetermined distance of other client devices and are directly connected to the WAP that the historical information was analyzed; and

generate a coverage monitor for the client device within a predetermined distance of a different client device.

4. The non-transitory machine-readable storage medium of claim 3, further including instructions to:

determine a region including an x coordinate position and a y coordinate position, the associated region representing a minimum region within a site map that includes multiple client devices; and

specify at least one coverage parameter for the associated region of the site model, the at least one coverage parameter including at least one of a minimum number of client devices and a minimum data rate.

5. The non-transitory machine-readable storage medium of claim 1, further including instructions to:

determine that change in configuration of the at least one WAP should include a change to an internal configuration of the at least one WAP.

6. The non-transitory machine-readable storage medium of claim 1, further including instructions to determine that change in configuration of the at least one WAP should include a change to an external configuration of the at least one WAP.

7. The non-transitory machine-readable storage medium of claim 1, further including instructions to:

select the second trial WAP configuration associated with the second coverage prediction having a greatest level of compliance with the coverage monitors among the second coverage prediction for the at least one second trial WAP configuration, if each second coverage prediction fails to satisfy at least one coverage parameter; and

identify the coverage monitor, among the plurality of coverage monitors, that is least satisfied by the second coverage prediction for the selected second trial WAP configuration.

8. A computing device, comprising:

a memory encoded with multiple instructions; and

a processor to execute the instructions, wherein the instructions, when executed, cause the processor to;

determine that a change to a wireless network configuration should be determined;

iteratively adjust at least one wireless access point (WAP) setting value for a set of WAP objects to generate at least one first trial WAP configuration, if an initial coverage prediction for an initial WAP configuration for the set of WAP objects fails to satisfy at least one of a plurality of coverage monitors;

iteratively adjust at least one WAP position value for the set of WAP objects to generate at least one second trial WAP configuration if, for each first trial WAP configuration, a first coverage prediction fails to satisfy at least one of the coverage monitors;

identify the coverage monitor least satisfied by a coverage prediction for a target WAP configuration if, for each second trial WAP configuration, a second coverage prediction fails to satisfy at least one of the coverage monitors;

alter a number of WAP objects in the set of WAP objects based on a region associated with the coverage monitor, wherein the change to the wireless network configuration includes identification of an alteration in the number of WAP objects;

provide the change to the wireless network configuration to a display device; and

modify the wireless network configuration based on the change, upon receipt of a user authorization of the alteration of the number of WAP objects.

9. The computing device of claim 8, further comprising:

a network interface, wherein the instructions, when executed, further cause the processor to;

receive, with the network interface, a set of WAP objects and an initial WAP configuration; and

select, as the target WAP configuration, the second trial WAP configuration associated with the second coverage prediction having a greatest level of compliance with the coverage monitors among the second coverage prediction for the at least one second trial WAP configuration.

10. The computing device of claim 9, wherein the instructions, when executed, further cause the processor to:
