802.11n design that will accommodate legacy clients

Hello,

I have a couple of questions regarding the best approach to designing a WLAN that will need to support both 802.11n and legacy clients (while maintaining the highest possible performance for the 802.11n clients). We will be utilizing a WLC 4400 with 1142 and 1252 access points.

Below is a quick summary of the features I intend to use.

- Configure a single WLAN/SSID for the entire network

- Enable 802.11n on just the 802.11a radios

- Disable 802.11n on the 802.11b/g radios

- Configure 802.11n clients to connect only using 5Ghz

- Utilize AP Groups throughout the network to limit the size of wireless subnets. All of these AP Groups will be mapped to the single WLAN/SSID.

Is there anything I have overlooked? Will this achieve the appropriate separation of 802.11n from legacy clients so that the 802.11n clients can perform at their best? Do I instead need to configure a separate SSID for the 802.11n clients?

Thanks for you help,

Steve

How do you know you don't have 802.11b clients?
In order to use 800.11n you need to enable WPA2/AES.

Re: 802.11n design that will accommodate legacy clients

We don't have any 802.11b clients that we need to worry about in this scenario.

We will be using WPA2/AES.

Specifically I'm more concerned as to whether my SSID and radio configuration structure will cause any issues for the 802.11n clients when legacy devices are present.
