Spectrum Analyzer software

[ruster]

Hello All,

Hoping someone might know the answer to my question. Wondering if there is any software product around which can turn my laptop equipped with a Cisco 350 PC Card into a spectrum analyzer? Not specifically to detect 802.11 devices, but to help discover any RF noise in areas which may cause interferance with 802.11a or b solutions. Would be most useful for site surveys.

If anything exists I'd appreciate knowing about it.

Take a look at Airmagnet website.

While the Airmagnet is not exactly a spectrum analyzer, it does scan the full frequency range and provide a real time screen of the outcome.

I have two version of a demo.. one in Microsoft player format but it must be downloaded and one in RealAudio format (realOne) that is streamed. Its the same video clip and shows this screen.

There are three companies who make software which will do what you're asking for - in a way. If you are looking to sweep the 2.4 gHz. range, Teletronics makes an 802.11 (2Mbps) card site survey survey package. As I recall, it goes for around $300.00.

Here's a link to their site.

Proxim's Rangelan2 also has a PCMCIA card which runs it's own sire survey software. If is pretty cool. You need to know it will not associate with the Cisco card as it is a frequency hopper. It does display the enitire frequency range and is easy to use.

Here's a link to their card:

And I believe the software can be found here:

The other PCMCIA card I have used is made by Symbol Technologies. These are the older design Spectrum24 cards (if you look around, the also made a 500 mw output card which really makes for great results. Here's a link to the website for Symbol's Spectrum 24 cards:

http://www.symbol.com/products/oem/oem_radioeng_la2400.html

http://www.symbol.com/products/wireless/la3021.html

And here's a link to the software:

http://www.symbol.com/services/downloads/dl_sp24_2mbps_tools.html

If the model number on the card has -500 after it, the card has 500 mw output.

Both the Proxim and the Symbol cards can be bought cheaply ($20-$30) on Ebay and the software is downloadable for each manufacturer's respective websites.

Hope this helps.

Thanks newisp. I'll take a look at the sites and see if it matches what I'm looking for.
