300 Configuring the Wireless Array
• Non-Radar: give preference to channels that are not required to use
dynamic frequency selection (DFS) to avoid communicating in the
same frequency range as some radar (also see Step 8 on page 287).
• Negotiate: negotiate air-time with other Arrays before performing a
full scan.
• Full Scan: perform a full traffic scan on all channels on all IAPs to
determine the best channel allocation.
• Include WDS: automatically assign 5GHz to WDS client links.
5. Set Cell Size: Cell Size may be set globally for all 802.11an IAPs to Auto,
Large, Medium, Small, or Max using the buttons.
