Table 16: Channel Optimization settings for US Country Code
Use this setting when
Description
Setting
You have a mixture of APs
that support DFS channels
and other DFS channels in
a Smart Mesh configuration.
DFS-capable ZoneFlex APs
are limited to the same
channels as all other APs
(non-DFS channels only).
Optimize for Compatibility
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.
ZoneFlex APs are limited to
non-DFS channels, plus four
DFS channels supported by
Centrino systems (may not
be compatible with other
wireless NICs).
Optimize for 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
ZoneFlex APs can use all
available DFS and non-DFS
channels, without regard for
compatibility or
interoperability.
Optimize for Performance
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 (including ZF 7731, P300, T300, and T710 series) are set to
a country code where these restrictions apply, the AP or Bridge can no longer be set to
an indoor-only channel and will no longer select from amongst a channel set that includes
