and #WFD7

Wireless Field Day 7 (#WFD7) is just around the corner and AirTight Networks is pumped about being in the vendor line-up.  This is our third WFD and certainly won’t be our last.

You won’t want to miss our session which takes place on Wednesday, August 6 from 13:30-15:30 (Pacific time).  Most vendor presentations – including ours – are streamed live at  Can’t make it for the live session? Keep calm and view video recordings of our presentations at your convenience.


Not Familiar with Wireless Field Day?

Wireless Field Day (WFD) focuses on wireless and mobility technologies, including Wi-Fi and mobile device management. This unique forum brings together the best independent thought leaders in wireless (referred to as the “delegates”) to discuss pressing issues and technology advancements with key companies in the space.

Wireless Field Day events started in 2011 and now feature two events per year. For 2014, WFD is on a first and third quarter cycle.

#WFD7:  August 6-8, 2014  (live and on-demand)


What Topics are Covered at WFD?

Wireless Field Day covers many diverse topics that are of interest to our delegates and their audience. In the past, companies have discussed the following areas:

  • Wi-Fi access point technology and implementation
  • Mobile device management, BYOD, and mobility issues
  • Spectrum analysis and site surveying
  • RFID and the “connected world”

For WFD6, AirTight had a mostly Managed Services Provider (MSP) themed set of presentations and demos.  #WFD7 will see AirTight expand on these topics in more depth.


On The Fly Wi-Fi

In an upcoming webcast episode of On The Fly Wi-Fi, Mike Leibovitz @MikeLeibovitz is turning the cameras around and chatting with Wireless Field Day 7 event organizers Stephen Foskett @SFoskett and Tom Hollingsworth @networkingnerd.


The Delegates have Spoken

In preparation for WFD7, some delegates have questions, make specific requests and also offer up some sound advice.

  • In his virtual mystic voice, Lee Badman sings his WFD7 predictions in “The Great Wireless Field Day 7 Blog” – even going so far as invoking Mr. Mojo Risin’ and the magical properties of the blue bus.  For Lee and the other delegates, we promise a great ride and some Wi-Fi mojo.  As for the online viewers, you’ll have to experience the mojo vicariously through the delegate blogs and Twitter chatter #WFD7.
    • Jennifer is great at capturing Wi-Fi in action as evidenced in Delta Wi-Fi.

Our personal Blake Krone favorite – notice the cute extras

Blake Krone differs from Jennifer in his approach to photos.  Blake is the action – can he outdo himself in the selfie and photobomb department?  With all the WFD7 Wi-Fi royalty on hand, he should have no trouble finding a memorable opportunity.

  • Can you say Cisco groupie?


All kidding aside, especially worth highlighting are 2 excerpts from “Preparing for Wireless Field Day 7” by Keith Parsons:

Reminder for vendors prepping for Wireless Tech Field Day coming up soon. Prepare for a technical audience!

Reminder for vendors prepping for Wireless Tech Field Day coming up soon. Prepare for a technical audience!


Focus on the technology


“Each of the sponsoring vendors has unique properties and technologies that set them apart from the competition – let us see those and help the delegates as well as all the video audience to see and experience those features!”


and nothing but the technology!


“If there is anything controversial about your company or products or technology, acknowledge it, and move on. It is all about the technology – that is what everyone comes to see.”


And that’s what we plan to do.


#WFD7:  Helium on the horizon?

Channel Bonding Caveats – Over and Above Spectrum Hogging

July 14th, 2014

Popular literature on 802.11ac describes 40 MHz and 80 MHz operation (channel bonding) as doubling and quadrupling of the data rate, respectively. Every time I saw that mentioned, the following question came to my mind.

When radio transmits over 40 MHz (or 80 MHz) channel, is the total transmit power proportionally increased over 20 MHz to maintain the SNR (signal to noise ratio)? And, how is the data rate multiple with channel boding distributed over the cell?

This question nagged me like a little stone in the shoe that is impossible to ignore. My subsequent findings from the lab tests show that the popular literature is only partially true. Read on to find out why. Read more…

Education Technology: Wireless as a Service, 802.11ac and Social Wi-Fi

March 14th, 2014

Read about trends in education technology: Wi-Fi as a subscription service, outlook for 802.11ac adoption in schools and integration of social media into wireless networking.

BETT 2014, UK’s learning technology show, has been and gone, but it certainly won’t be forgotten! For those in the educational technology sector, be it primary school teachers all the way to network managers of colleges and large secondary schools, this was THE event and is memorable for new technology and aching feet from over 4 days of the conference.

Wireless as as Service for Education

So what was all the fuss about and why was #BETT2014 trending on the social feeds? There were a few noticeable trends this year noted by attendees and exhibitors alike. Firstly came “XXX as a service”! As educational funding changes, so does the need to adapt and service the new legislation whilst still enabling the educational IT needs in what is a constantly evolving technology landscape.

HIMSS 2014 – Big on Wireless

March 6th, 2014

This year’s show was huge. According to the events organizers, there were 1,200 exhibitors and 38,000 healthcare professionals in attendance and there were more nurses, physicians, IT staff and executives in attendance at this year’s HIMSS than ever before.

One of the most interesting Wi-Fi capable devices at this year’s HIMSS was a Wi-Fi enabled bionic exoskeleton. The Ekso Bionics unit (pictured above) was featured in the Lockheed Martin booth. This device is for patients with lower extremity paralysis or weakness. It enables patients to stand, walk and it can assist them with their rehabilitation. The unit is equipped with a single Wi-Fi radio. The radio supports two data streams currently. One stream allows engineers to see real-time telemetry data to determine how the unit is performing. The other stream is for the unit’s user, where information such as steps taken, distance traveled, etc., are sent over the air to an application that the user can access later.

Bang for the buck with explicit beam forming in 802.11ac

October 16th, 2013


Bang for the buck with explicit beam forming in 802.11ac

802.11ac has brought with it MIMO alphabet soup … spatial streams, space-time streams, explicit beam forming, CSD, MU-MIMO. Alphabet soup triggers questions to which curious mind seeks answers. This post is an attempt to explore some questions surrounding explicit beam forming (E-BF) that is available in Wave-1 of 802.11ac. E-BF is a mechanism to manipulate transmissions on multiple antennas to facilitate SNR boosting at the target client.

How is E-BF related to spatial streams?

E-BF is a technique different from spatial streams. E-BF can be used whenever there are multiple antennas on the transmitter, irrespective of the number of spatial streams used for transmission.

MU-MIMO: How may the path look like from standardization to implementation?

September 26th, 2013

In earlier blog posts on 802.11ac practical considerations, we reviewed 80 MHz channels, 256 QAM and 5 GHz migration. Continuing the 802.11ac insights series, in this post we will look at some practical aspects of MU-MIMO, which is the star attraction of the impending Wave-2 of 802.11ac.


MU-MIMO mechanics and 802.11ac standard

At a high level, MU-MIMO allows AP with multiple antennas to concurrently transmit frames to multiple clients, when each of the multiple clients has lesser antennas than AP. For example, AP with 4 antennas can use 2-stream transmission to a client which has 2 antennas and 1-stream transmission to a client which has 1 antenna, simultaneously. Implicit requirement to attain such concurrent transmission is beamforming, which has to ensure that bits of the first client coherently combine at its location, while bits of the second client do the same at the second client location. It is also important to ensure that bits of the first client form null beam at the location of the second client and vice versa.
