Installing the Wi-Fi Array 67
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 Wi-Fi Arrays or other Access Points. To enable
the Sharp Cell feature, go to “RF Power & Sensitivity” on page 298. For more
information about this feature, see the Xirrus Sharp Cell Application Note in the
Xirrus Library
.
Roaming Considerations
Cells should overlap approximately 10 - 15% to accommodate client roaming.

Allocating Channels
Because the Wi-Fi Array is a multi-channel device, allocating the best channels to
radios is important if peak performance is to be maintained.
Automatic Channel Selection
We recommend that you allow the Array to make intelligent channel allocation
decisions automatically. In the automatic mode, channels are allocated
dynamically, driven by changes in the environment. Auto Channel assignment is
