Broken Antenna

Is there any way (debug, trap,...) the AP can send/show if the external antenna is broken or disconnected? We have lots of AP's installed in a place where sometimes the external antennas can be broken, and I'd like to know if there is a way to know it at the time it happens.

Thanks.

You can look at the associations to see if users associate or not to the ap. Other than that, you must walk and associate to each ap.

Re: Broken Antenna

Run an external monitor, something like NetStumbler (free: http://www.netstumbler.com).

Baseline the working system and watch for a major drop in the signal level.

You could probably write a Perl script that would telnet the AP (using Net::Telnet, for example) and track the RSSI (Radio Signal Strength Indication) from the AP- this is receive only, but if the majority of hosts are running at minimum marginal levels you can probably track & chart it.

You can put in something like a "Bird" meter (measures power and (I think) SWR) - if you have a screwed-up antenna, the SWR is gonna go up significantly. There will be losses associated with an in-line system.

Video camera?

That's all that comes to mind tonight ...

Good Luck

Scott
