NOTE: If you are located in the United States and have a DFS-capable ZoneFlex
AP that is expected to serve as a Root AP (or eMAP), with a non-DFS-capable Mesh
AP as its downlink, you will need to set the Channel Optimization setting to "Optimize
for Compatibility." This is due to the DFS-capable AP's ability to use more channels
than the non-DFS-capable APs, which could result in the RAP choosing a channel
that is not available to the MAP. Alternatively, manually set the channel for the Root
AP to one of the non-DFS channels. Specifically, choose one of the following
channels: 36, 40, 44, 48, 149, 153, 157, 161, 165.
The channels available for AP use are the following:
• Optimize for Compatibility : 36, 40, 44, 48, 149, 153, 157, 161, 165 (non-DFS
channels).
• Optimize for Interoperability : non-DFS channels plus channels 52, 56, 58, 60.
• Optimize for Performance : all DFS/non-DFS channels, including 100, 104, 108,
112, 116, 120, 124, 128, 132, 136, 140.
Channel Mode
Some countries restrict certain 5 GHz channels to indoor use only. For instance,
Germany restricts channels in the 5.15 GHz to 5.25 GHz band to indoor use. When
ZoneFlex Outdoor APs and Bridges with 5 GHz radios (ZoneFlex 7762, 7782, 7761-
CM and 7731) are set to a country code where these restrictions apply, the AP or
Optimize for
Interoperability ZoneFlex APs are limited to
non-DFS channels, plus four
DFS channels supported by
Centrino systems (may not be
compatible with other wireless
NICs). You have only DFS-capable APs
in your network, or Smart Mesh
is not enabled, and you are
confident that all wireless
clients support DFS channels.
Optimize for
Performance ZoneFlex APs can use all
available DFS and non-DFS
channels, without regard for
compatibility or
interoperability. You have only DFS-capable APs
in your network, you are not
concerned with DFS
compatibility of client devices,
and you want to make the
maximum use of all possible
available channels.
