4 . The NMS of claim 3 , wherein the operating parameters comprise at least one among a transmission power level and a channel of operation for each of the WAPs.
5 . The NMS of claim 1 , wherein the NMS is remotely located from the plurality of WAPs.
6 . The NMS of claim 1 , wherein portions of the plurality of WAPs are located within one among a residence, and a commercial building.
7 . The NMS of claim 1 , wherein the controller is programmed to:
receive location readings from a portion of the plurality of WAPs; and
reconfigure the at least one of the plurality of WAPs according to the location readings.
8 . The NMS of claim 1 , wherein the controller is programmed to:
determine a location for each of the plurality of WAPs according to a Service Set Identifier (SSID) of each of the WAPs; and
reconfigure the at least one of the plurality of WAPs according to its location.
9 . The NMS of claim 1 , wherein the controller is programmed to:
monitor at least one operating parameter of a portion of the plurality of WAPs; and
if radio interference between the WAPs can be improved, reconfigure operations of a portion of the plurality of WAPs while monitoring for an improvement in the at least one operating parameter of the portion of the plurality of WAPs.
10 . The NMS of claim 9 , wherein the at least one operating parameter comprises at least one among a data error rate, a signal to noise ratio, and a maximum data rate of a select WAP.
11 . A computer-readable storage medium in a network management system (NMS), comprising computer instructions for selectively reconfiguring operations of at least one of a plurality of WAPs to reduce radio interference between the plurality of WAPs.
12 . The storage medium of claim 11 , comprising computer instructions for selecting one among channels 1 , 6 and 11 to reduce radio interference of the at least one of the plurality of WAPs.
13 . The storage medium of claim 11 , comprising computer instructions for selectively reconfiguring operations of the at least one of the plurality of WAPs according to at least one among a physical location of each of the plurality of WAPs, relative positions of the plurality of the WAPs, and operating parameters of the plurality of WAPS.
14 . The storage medium of claim 13 , wherein the operating parameters comprise at least one among a transmission power level and a channel of operation for each of the WAPs.
15 . The storage medium of claim 11 , wherein the NMS is remotely located from the plurality of WAPs, and wherein the plurality of WAPs are located within one among a residence, and a commercial building.
16 . The storage medium of claim 11 , comprising computer instructions for reconfiguring the at least one of the plurality of WAPs according to location readings received from a portion of the plurality of WAPs.
17 . The storage medium of claim 11 , comprising computer instructions for reconfiguring the at least one of the plurality of WAPs according to its location relative to the other WAPs.
18 . The storage medium of claim 11 , comprising computer instructions for
monitoring at least one operating parameter of a portion of the plurality of WAPs, wherein the at least one operating parameter comprises at least one among a data error rate, a signal to noise ratio, and a maximum data rate of a select WAP; and
if radio interference between the WAPs can be improved, reconfiguring operations of a portion of the plurality of WAPs according to the at least one operating parameter monitored.
