Excited to hear Avaya present at Wireless Field Day 7!



There's a great lineup of presenters at the upcoming Wireless Field Day 7! Mark your calendars for August 6th - 8th. As always, the presentations will be streamed and recorded so you won't miss anything even if you have to miss it during the first airing.

You can tap into the live stream at www.techfieldday.com once we're on the air.

I'm excited to hear about what is going on at Avaya around their wireless offering. A little birdie recently told me about how many ex-Cisco/ex-Juniper employees are now a part of the Mobility team over at Avaya. If people who have been in the Wi-Fi business for over a decade (or more!) are moving over to Avaya's Mobility team, you know something terribly exciting is going on.



The full list of sponsors has filled out quite nicely:

AirTight
Aruba
Avaya
Cisco Mobility
Extreme Networks
Fluke Networks

I'm glad to be invited once again, and I'm looking forward to meeting the one new WFD delegate who I haven't already met! I'm talking about you, Glenn Cate!  
It'll also be nice to spend some time catching up with all the familiar faces who've been invited back.

Wireless Site Survey Rigs (a repost)

Site Survey Rigs

(an archive of my CWNP post)

I’ve been traveling to customer locations to perform wireless site survey work for over four years now, and I can assure you traveling with survey gear can be somewhat tricky, especially if you’re like me and want to avoid checking your bags at the airport. I’ve seen many a survey kit arrive in pieces as a result of the thorough TSA checked baggage ‘screening’. As a result, I’ve come up with some fool proof ways of flying with survey gear stored in my carry-on luggage, while doings so in a way that I’m not holding up the TSA security checkpoint line. 
The gear I carry with me to do an active site survey is a Tessco battery pack, a Cisco 1140 access point (or a Cisco 3500 CleanAir access point), a roll of duct tape, colored ½ inch stickers, a Sharpie, a roll of transparent tape, and the mounting bracket for the 1140/3500 access point. The mounting bracket uses the metal mounting bracket that ships with the 1140/3500 series access point and a wooden block threaded for a painters’ extension pole. The wooden block was at one time a drywall texture brush.

I removed the bristles with a pair of pliers and then spray-painted the wood block gloss black to look more professional.


A pair of Mr. Longarm Angle Adapters allow me to suspend the 1140 access point from the wooden block bracket as if it were installed on theceiling.


I have seen someone use a plastic backed drywall texture brush as their mount for an 1140 bracket, but I don’t have a dremel to grind down the plastic mount to allow for the bumps on the back of the 1140 flat metal bracket.

Those are the basic parts I need to perform an active site survey at the customer location.
Before I discovered Ziploc XL bags at Home Depot I had to pull out the access point and power supply and put them in a bin, and now I use one of these gigantic bags to carry all the survey gear. I can zip open my carry on suitcase and lift all the survey gear out and put it in an x-ray bin in one swift movement.


Since a survey cart is too large to count as carry on luggage, and often don’t have enough early warning about a site survey to ship anything to the site, I’ve had to make do with things that wouldn’t normally pass as a survey cart.  The customer sometimes will have an A/V cart or a utility cart that I can use to survey with, but sometimes I have to be a bit more creative.  I’ve made do with items you wouldn’t normally imagine passing as a cart for surveying. I use the following as examples: the survey kit pelican case, an office chair (works if it is a really small survey); a furniture moving cart, a furniture dolly, and sometimes I even had a proper Rubbermaid cart to use.





The things I can’t travel with are the Mr. Longarm 12 foot painter’s pole and a dowel rod. These items can be found at any Home Depot, and there has been a Home Depot within driving distance of every site I’ve had to survey. I use the dowel rod to attach the ¼ inch round labels combined with the transparent tape to the suspended ceiling grid to mark the access point installation locations.  I fold the transparent tape into an “L” shape and then stick the tape to the suspended ceiling grid.  This works much better for me than having to find and drag a ladder around with me so I can reach the ceiling to manually mark the access point installation locations.

Several other wireless engineers I’ve worked with have designed their own outdoor survey rigs by using perforated sheet metal strips and crafting survey tripods out of this held together with bolts and wingnuts.  I have also seen survey rigs for outdoor point to point feasibility testing crafted out of sections of PVC pipe.  PVC piping is very sturdy, disassembles easy, and can be used in a multitude of ways to create a survey pole or survey mounting structure.  My friend Jeff Russell has made an outdoor rig for doing a mesh survey from PVC piping, and an indoor tripod mount out of perforated metal (photo gallery at this link).



There are certainly a million different ways to craft a survey rig out of commonly available parts from your nearest hardware store.  The only limit seems to be your imagination.
