Such a waste to use a 1250, instead of a 1240, for bridging use only. My 2 cents ...

Hi Giovanni,

Are you using the AIR-ANT3338 on AP 1252G to bridge the link?

The antenna is definitely supported, that document is just geared more towards what 1252s are normally used for. As long as the connector is the right type (RP-TNC) and it's meant for the correct band, the antenna will work. There's nothing to look at beyond those two things.

However, I'm not sure that Cisco allows 802.11n data rates to be used in bridge mode. Before purchasing this solution, I would call your Cisco rep to ask this question. And if you find out, please let me know! I'm quite curious. :)

Hi Giovanni,

After reading Jeff's post, I got curious too and found this link. Apparently, Cisco TAC doesn't support bridging using the 1250 but a number of posters have successfully implemented it. Here's the link:

http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=Getting%20Started%20with%20Wireless&topicID=.ee7c7c3&fromOutline=&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.2cd28df1

So I guess, it does work! Blimey!

Hope this helps.

Hi all,

I received the response from Cisco about the possibility to install the dish antenna on AP 1250.

The response is:

Cisco has tested the bridge with AP 1250 on short distance but not with the Dish Antenna.

This means that this configuration is not supported by the TAC in case of issue.

Also with only one antenna the data rate should be 157Mbps with an effective throughput of half of that.

If the customer agree with me I think that I will try.

If I will do this installation I will inform you.

Regards

Giovanni
