thanks

ive been looking at this cheapo thing too.

we've got a 10,500 sq foot room with 100 foot ceilings that we're doing pos in.
it's a bloody rf nightmare ....

and even worse ticket sales are processed over telnet which constantly
disconnects.

when there are a lot of people in the room it gets worse.

we've tried adding ap's but that only overlapped coverage and increased roaming.

i'm also thinking about high-gain or industrial antenna's

In a situation like that, there's a lot to be said about old-fashioned copper cable.....

That little device your looking at might just do the trick. I pointed you to Fluke because I've used their test equipment for years and I'm really satisfied with their products and service. But on a strict budget, that wi-spy could be what you're lookin' for.

Shoot, with our budget situation the way it is right now, we might not even be able to afford the wi-spy.

my point exactly ..... but the administration wants wireless in that room
since it can be broken down and set up by non techies for events.
also due to a "historical significance" we can't mount industrial antenna's.
I'm looking at the linksys high-gain thingyto attach to the ap's.

i got it
it's pretty cute
been playing with it for two days at home
cordless phone, microwave.

we found a microwave in a close by office that overlaps on channel 11
we turned it on and watched a big rectangle cut through the signal on the spectral analysis.

(which one on the pos ap's was set for) now they're set for 1,6

In a large area, think about using higain antennas before you bump up your transmission power. If your wireless stations are fixed, a few directional antennas will do wonders, and they don't need to be "industrial" to be effective. Mobile wireless stations require a larger field coverage depending on where they are able to move to. Panel antennas may be all that you need. See what's on sale at ebay.com.

Dear xxxxxx,

Network professionals pursuing the Advanced Wireless Design Specialist and Advanced Wireless Support Specialist certification now have a second training option to help them prepare for the required certification exams: Candidates will be equally prepared for the required Wireless certification exams no matter which path they choose. To prepare for the certification exams, candidates need to know all of the material covered in either path 1, or path 2:

Path 1: Take two classes: Cisco Wireless LAN Fundamentals (CWLF) and Cisco Wireless LAN Advanced Topics (CWLAT).

These classes use a blended approach to teach the skills and knowledge required to design, install, and support Cisco® Aironet® and Airespace wireless products. The two classes combined total eight days of classroom training. This path offers accelerated preparation for the required certification exams.

Path 2: Take three classes: Aironet Wireless LAN Fundamentals and Site Survey (AWFSS), Aironet Wireless LAN Advanced Topics (AWLAT), and Cisco Unified Wireless Networking (CUWN).

These classes teach candidates about Airespace and Cisco® Aironet® products separately: CUWN focuses on Airespace, while Cisco® Aironet® products are taught in AWFSS and AWLAT. Combined, these three classes impart the same skills and knowledge as the classes offered in Path 1. Take path 2 if you’d prefer to spread your training out over a period ot time,or need training on just Cisco® Aironet® or Airespace alone.

Advanced Wireless Design Specialist 642-586 AWLANSE Path 1:
Cisco Wireless LAN Fundamentals (CWLF)
Cisco Wireless LAN Advanced Topics (CWLAT)

Or
Path 2:

Aironet Wireless LAN Fundamentals and Site Survey (AWFSS)
Aironet Wireless LAN Advanced Topics (AWLAT)
Cisco Unified Wireless Networking (CUWN)

Advanced Wireless Support Specialist 642-587 AWLANFE Path 1:
Cisco Wireless LAN Fundamentals (CWLF)
Cisco Wireless LAN Advanced Topics (CWLAT)

Or
Path 2:

Aironet Wireless LAN Fundamentals and Site Survey (AWFSS)
Aironet Wireless LAN Advanced Topics (AWLAT)
Cisco Unified Wireless Networking (CUWN)

i left something out ....
the staions are "old" pc's using the aironet 350 pci cards (win2k).
under a desk.
we bought cables to extend the antenna's above the desks to about eye level.

Probably not gonna find software that will turn your PCMCIA card into a spectrum analyzer. You can find tons of software that will show 802.11B traffic. Check out these guys for SA's.

The good thing about the Avcom units, you can get up/down converts to target different spectrums.

Also Anritsu Site Masters are badass, you can normally find them on ebay. Tektronix 491's are good too.

If it doesnt need to be mobile you can find the good 'ole HP 8565a's, they weight a ton but can do 10Mhz to 22Ghz and I think there is an option to even go to 44Ghz, but I could be mistaken.
