AirTight offered early beta access to WizShark, our visual WiFi troubleshooting tool in cloud, and since then it has been a fun ride for the team. It was heartening to see a number of WiFi professionals taking interest in the tool and appreciating its graphical representation of packet captures. Of course, the positive feedback was accompanied with, as expected, feature requests!

Apart from graphical representation, we also want to empower collaboration and reporting using this tool. Hey, when people work on tools in cloud, this is expected already, right? Starting on this path, we have added capability for seamless collaboration for team troubleshooting.

Share current views with team members

Old school troubleshooting is with “Share this file with…” functionality, but then it only allows sharing raw traces and not troubleshooting milestones. Realizing that, we added capability in WizShark to share current views with team members. Now there is a button on WizShark menu to share the current view to bring your colleagues up to speed on what you have discovered so far.

Share troubleshooting milestones with team members

Clicking on this Share button will open up the Share View dialog which generates a link that you can share with your peers. Your colleague will be on the same page as you in no time, including all the frame-filtering, zooming and slicing that you may have performed on the graph. From this point on, both of you can analyze the graph independently.

Easily create reports for management, customers or troubleshooting community

And then there are times, when you have successfully troubleshot the issue using WizShark and then you want to generate a report for your managers, your customers or for the troubleshooting community. Simply click on the Save as Image icon just above the graph. Save the view in your preferred image format (.png or .jpg) and embed it in your report.

WLAN Pros Europe: Hang Out With AirTight Experts

July 21st, 2014

WLAN Pros Conference is coming to Europe! As Keith Parsons (the conference’s chair and founder) puts it, “the Wireless LAN Professionals EU Summit consists of three days of fun, great topics, awesome gear, and wonderful networking.”

wlan-pros-europeAnd we are excited to have two of our technical gurus – Allen Walker out of the UK and Rick Farina from the US - presenting. As luck would have it, the organizers put the two sessions in the same time slot, so unless the attendees are completely slacking, they won’t be able to avoid both Rick and Allen at the conference.

What will they be speaking on?

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…

Why #EdTech Needs Wi-Fi? And How FCC Aims to Help

July 2nd, 2014

ISTE 2014, the largest US education technology conference, closed July 1 – good-bye, Atlanta! The time frame coincided with new developments around FCC’s proposal to close the E-rate’s “Wi-Fi gap”; we cover these below. 

notatisteAs always happen with these large events, not everyone can go. But educators are a creative bunch. Rather than feeling left behind, they organized a parallel #NotAtISTE14 conference – complete with presentations, virtual badges and ribbons, Google+ community and hangouts, Twitter chats, karaoke (!), challenges and prizes. (Links and resources pertaining to a #NotAt… conference are at the end of the post).

We reached out to the community with a contest asking why they needed Wi-Fi for education technology initiatives.

A summary of the tweets are below, with responses ranging from robotics and iPad carts, to working with special ed kids and spurring creativity in students.

802.11ac Deeper Dive Webinar Recap

June 30th, 2014

Last week, AirTight’s Senior Technical Marketing Engineer, Robert Ferruolo (@RAFerruolo), added another chapter to the AirTight 802.11ac webinar series.  Robert presented on “802.11ac Deeper Dive” focusing on features that come along with the 802.11ac wireless platform.

Webinar recording image

During the presentation, Robert broke down channel availability, QAM, beamforming, MIMO, MU-MIMO, frame aggregation, and error correction.  To view the recording, click here.

Throughout this 6-part series, we’ll continue to break down why 802.11ac should be a serious consideration for your wireless network. The series will address the inevitable migration from 802.11n to 802.11ac.

We’ll be continuing to post our Q&A sessions for all of our webinar series. Stay tuned for more updates on upcoming webinars and their corresponding Q&A sessions.

Suddenly, Everyone Attacks Monetization – Wi-Fi Offload Summit, Day 1

June 19th, 2014

The Wi-Fi Offload Summit is taking place in Palo Alto through today, June 19. Lots of interesting perspectives on what Wi-Fi offload is, Wi-Fi monetization and how to go about it, along with privacy discussions and the future of mobile network operators.

See-full-presentation-on-SlideShare

See Anthony’s presentation on SlideShare

The number of solutions (and vendors) in the Wi-Fi monetization space seem to have exploded in the last 18 months. There are options for

  • Pure-play Wi-Fi presence analytics
  • Pure-play social engagement
  • Social engagement integrated with Wi-Fi and social media monitoring focused on SMBs (similar to what our partner Frontera Consulting is doing in this space)
  • AirTight’s approach of integrating Wi-Fi, presence analytics, brand engagement and compliance/security

Antony Paladino, AirTight’s president of technology services, focused his session on “unconventional engagement” – using Wi-Fi to connect communities, develop company culture, and, yes, fight crime!

Wi-Fi Offload Summit: Who Will Monetize Your Brand?

June 17th, 2014

With the theme of “Monetize Thyself!” AirTight speakers will tackle issues of real-time business intelligence, user engagement and creating value from Wi-Fi investments. Update: Please see our recap of Day 1: Suddenly, Everyone Attacks Wi-Fi Monetization.  

offload3

In today’s environment even the non-traditional telecom companies are jumping into the big data and monetization fray, as seen in Google’s leaked plans to offer free Wi-Fi equipment to local businesses and Facebook’s integration of its sign-on with Wi-Fi.

Most recently, Apple announced plans to obscure MAC addresses in iOS 8 potentially impacting Wi-Fi presence analytics. The change in iOS 8 was heralded as a privacy win, but astute observers noted that the move supports Apple’s iBeacon technology, which collects location data much more comprehensive than information inferred from MAC addresses.

Carriers need to ask themselves: “Are you willing to have Google, Facebook or Apple monetize your brand, or would you rather do it yourself?” With tools and solutions available today, carriers do not have to give up control (and monetization opportunities) to others.

Wi-Fi Hacking 101 – Ethical of Course! (+ Video)

June 4th, 2014

Watch the video from Wi-Fi Hacking 101 event series with Rick Farina, AirTight Networks senior wireless security researcher and resident hacker.

“Security? Who cares,” I hear most people say. They would quickly change their mind if they had met Rick Farina, AirTight’s ethical hacker (known on Twitter as @RickLikesWIPS). UK resellers got the opportunityat a series of Wi-Fi Hacking Events  in May. The audience definitely got more than they bargained for with these workshops.

rick-farina-hacking101In attendance were partners who sell into all verticals varying from schools and colleges to banks and retailers. Rick was not only able to demonstrate the importance of providing a secure wireless solution, he showed the audience a range of wireless threats that hackers from around the globe may use to steal sensitive data.
