[olug] WiFi site survey?

[Shawn Mattingly]

Airmagnet is the Cadillac of site survey tools, both in price and functionality.  If you are a pro doing site surveys this is the software you have to use to be taken seriously by other wifi guys.  The full suite of tools priced well out of reach of the average IT guy ($10K+).

If you have more modest requirements and budget you might want to look at either Ekahau or Visiwave.

Just to provide feedback to the list, here's the list that I came up with.



1: There were no specific local companies suggested, but a few people

mentioned contacting manufacturers directly to see if they have a list of

suggested local reps that could perform the WiFi survey.



 * Cons: The big downfall to this is that the survey may be done with only a

specific brand of AP in mind.



 * Pros: The benefit is that the survey cost may be deducted from a final

purchase price.







2: I got a number of recommendations for tools to perform the survey

yourself:



 * AirMagnet by Fluke:

http://www.flukenetworks.com/enterprise-network/wireless-network/AirMagnet-Survey



  * IIRC, this is one of the tools that I have seen in past jobs used by

wireless surveying companies.  I can't speak to it's price nor ease of use.



 * AeroHive: http://www2.aerohive.com/l/1244/2010-05-05/GYKAL



  * Video on page that walks through using the on-line site-mapping tool,

but only has "AeroHive" APs.



  * Probably not a bad tool to play with to get some rough what-if ideas

since 802.11 radio signals should behave similarly regardless of vendor.  (If

Rodger D were still here, I'm sure we'd get a write-up on the propagation

differences based on subtle antenna lengths and placement.)



 * TamoGRaph: http://www.tamos.com/products/wifi-site-survey/



 * WaveDeploy: http://www.veriwave.com/



  * Free version does basic signal strength estimating



  * Purchased products also perform additional computations to determine

differences between 11g vs 11n networks, VoIP vs streaming video

experiences, and other factors.





If I were doing this on zero/small budget, I'd look at the AeroHive site

first and spend the time uploading the current floor plan and see how it

matches with real world.  Then have it do the what-if and see if the

suggestions seem sane.



After that, I'd suggest either hiring a professional or buy one of the tools

and start learning all about signal propagation, interference patterns,

attenuation due to walls, floors, etc. :-)
