Re: WLW052 – 7 Rules for Accurate Site Surveys

Arsen Bandurian — Tue, 18 Feb 2014 17:15:07 -0000

Passive survey is about coverage quality. Coverage is (or is not) there regardless of the device type.
Of course, performance of devices differs, but that matters when doing Active surveys. Thankfully, iPerf was ported onto almost every platform that exists. Some vendors, like Auba, even include it as part of their on-device tools.
Not an ideal solution, but can augment Active survey data done with professional software. Typically involves running a cart with one laptop runnings something serious and a bunch of other client devices recording data along the same path.
Keith, what's your take - is it one of the 'poor active survey - better not do it at all' scenarios? It's better than nothing.

Great stuff! Highly useful and enjoyable.

One thing that wasn't mentioned, though, is survey software that actually DOES take walls/etc into account when doing extrapolation.
Motorola's LAN Planner is the one.

hi Keith,

Very nice article indeed. I am trying to setup the AE6000 with Omnipeek and downloaded the Ralink v3.2.4.5 drivers from the mypeek portal however the install hangs in device manager unless I unplug and replug back in the USB adapter. When that's all done the adapter installs and is constantly disabled. Do you have a copy of the drivers you used during the session?

Edit: Please ignore. It is the Beta Ralink Driver – Version 5.0.7.7 as posted by Todd. https://mypeek.wildpackets.... Hope this helps someone else who runs into this problem

Pete

You are correct - it is difficult to get 100% accuracy when the client devices are all over the map. But... an accurate survey can be internally consistent. It can be consistent between sites. It can be a tool to confirm and validate your WLAN meets certains specifications.

Thanks for your time Keith, the podcast was great!

However, site surveys can't be accurate and it will never be. When you do pre-deployment survey you are using some kind of USB device, yes? You collect the data, do all the analysis, prepare the report... But in real world, users will use various type of devices, with various WLAN cards/drivers/antennas... And sometimes, you can't know it! What is your advice?

I hate to contact you this way, but the email I have for you (mail@wlanpros.com) isn't working. Can you email me at hobart@vocalizepr.com?

Hi Keith,

How you got that 3d-view on chanalyzer? I have chanalyzer pro on windows (the newest version) but there is nothing similar.

Nice article. I have a question. Where did you obtained driver for AE6000? I was looking for driver on Wildpackets site but with no success. Can you upload it somewhere, or send it to me by e-mail, please?

I love how Linksys's marketing pictures show the card in a MBP, but it only supports Windows ;-)

Re: All About Wireless LAN 102: The Answers to Your Questions

Hi Pros, I am busy with some studies and would like your opinion on this question. The question is as follows....
802.11a supports different modulation techniques,each allowing for different data rates.This adds complexity and cost to the radio. The Manager suggests 802,11zzz should only support one modulation technique, namely the maximum data rate possible. Do you support this idea? Why or why not?

Re: Access Point Installer Checklist

KeithRParsons — Thu, 15 Aug 2013 10:26:43 -0000

Thanks for the comments. It's far better to find out these issues *before* the AP is broadcasting in the air. After the AP is on, everyone will try to troubleshoot it as a "Wireless Problem".

Re: Access Point Installer Checklist

Alex — Thu, 15 Aug 2013 10:20:47 -0000

Thank you for sharing this. It definitely helps. Only recently I discovered how useful it is to have a checklist for AP installation (to prevent wire-side issues, such as an AP negotiating 100M uplink instead of 1G).

Re: Fast, Free & Easy Public Wi-Fi – A Cost of Doing Business

bob — Mon, 12 Aug 2013 10:08:39 -0000

You could ad, Wifi in hôtel is the busiest place. No other "place" where there is so much customers. so of course it is a priority.
Not agree when u say, it is a cost pb, on Internet access. It is almost a technical pb, a BYOD paradigm. No control, on what they do, what they bring, how configured they are, it is total surprise.
And very often, 9/10, when customers, say "wifi sucks", you look at the machine, and, u see no firewall ("what's that?"), sharing activate by one or other way, VNC, DropBox, files, iTunes Lib and so on... totally forgot, they are on a big public LAN! with unknown machines doing unknown things.

Good write up, Keith. Just ordered that device and was a bit concerned after some of the tweets from WFD about installation!
