Spectran? Are you talking about the software for a PC sound card? That's not going to do what you want, for sure! There really isn't a cheap solution.
What wireless gear do you use? If it has an external antenna input you should be able to attach a very high gain antenna (and an attenuator) and go on a real live "fox hunt" You can rent a spectrum analyzer as well, but it is pricey! I'm using one from Rohde and Schwarz. A 0-3 GHz one goes for $450.00 - $640.00 per month -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Ireton Sent: Sunday, October 01, 2006 11:34 AM To: [email protected] Subject: [WISPA] Diagnosing interference In our neck of the woods we have some areas where 802.11 systems simply do not function, period (and this is across a range of frequency bands and equipment manufacturers). And sometimes, in some limited cases, we will have a sub who appears to be experiencing interference that is much louder than our rssi at the sub (say they have a -63, but they still can't reliably hear the ap well enough for communication) and there's nothing really obvious in the area we can see. We know it's radio interference because we can play the channel flipping game, but we'd like to be better than that and actually diagnose the problem and identify the source and direction of the transmitter creating the problem, so that we can plan better and actually provide a resolution that will last for that sub. We know about spectrum analysis and such and actually own a handy unit (the Spectran) but it doesn't give real time data useful for direction finding. What are some of the other tools (hand held or truck mounted, not built-in firmware features) you folks use for this? If we had a tool that would just give us knowledge about the non-household applications present in these areas (where non-household is anything with a larger gain antenna and/or power output than a cordless phone or wireless access point), we could even go so far as to try and coordinate with those applications for the betterment of everyone. But just waking up one morning and learning a long time customer now has an Interference problem you have no way to resolve other than by terminating the business relationship, just really sucks ass in my opinion. And when you run out of tricks like new antennas, equipment, alignments and such, that's exactly what you're left with.
