I have a Cisco MSE 7.6.100 with Cisco PI 1.4 and Virtual controller 7.4.121 and 3 APs (3600,3600 and 1600) to make the MSE to detect the location in accurate but I found that when I moved from Area to another Area (each area is covered by AP) the wireless client not associated on the New AP that is on the new Area which reflect on the accuracy of the Location detection.
If you have issues you handover you need to make sure that the overlapping between the channels is proper and the 50 % overlapping is there.
When designing a WLAN, overlapping RF cell coverage is necessary to provide for seamless roaming. However, the overlapping coverage cells should not have overlapping frequency space. In the United States there are only three channels (1, 6 and 11) that do not share frequency space. RF is a half-duplex medium that allows for the transmission of only a single radio on any frequency channel, therefore when three or more 2.4 GHz APs are needed to cover an enterprise facility, only the non-overlapping channels of one, six and eleven should be used.
802.11b/g/n Wi-Fi radios can transmit in the 2.4 GHz band with a total of fourteen available channels. In the US only eleven of those channels are legally available and only 13 are available in Europe.
within the 2.4 GHz band, only three channels have non-overlapping frequency space: channels one, six and eleven.
