Wireless Array
32 Installing the Wireless Array
If you are installing many units in proximity to each other, we recommend that
you use Auto Cell Size; otherwise, reduce the transmit power using manual
settings to avoid excessive interference with other Arrays or installed APs. See
also, “Coverage and Capacity Planning” on page 28.
Sharp Cell
This patented Xirrus RF management option automatically creates more
intelligently defined cells and improves performance by creating smaller, high-
throughput cells. By dynamically limiting each cell to a defined boundary (cell
size), the trailing edge bleed of RF energy is reduced, thus minimizing
interference between neighboring Wireless Arrays or other Access Points. To
enable the Sharp Cell feature, go to “RF Power & Sensitivity” on page 316. For
more information about this feature, see the Xirrus Sharp Cell Application Note in
the Xirrus Resource Center
.
Roaming Considerations
Cells should overlap approximately 10 - 15% to accommodate client roaming.

XR500 Series radios are omni-directional rather than directional (sectored),.
This feature is not applicable to these Arrays.
