NETSCOUT AirCheck G2 v2.0

We had the opportunity while visiting with NETSCOUT at Mobility Field Day 2 to get a sneak peek of the v2.0 firmware for the G2 (yes, firmware; no need to purchase new hardware).  Many of us were very excited to see some of the newly added features and it seems as though there is even more room to grow in the future.  What we have come to trust as one of our favorite go-to tools in the wifi toolbag has only gotten more powerful and useful.  I am not going to go into a deep dive of each of the features that Chris Hinsz showed us but I will share the links because he does a way better job explaining it (because he is the Product Manager of course).

Notable features in the v2.0 release are iPerf, captive portal support/testing, interferer identification, and packet captures.  Also introduced was the NETSCOUT “Test Accessory” which will function as an iPerf server and can be placed anywhere there is a network connection with POE.

The additional features that are being introduced show that this product is as versatile as ever and should increase the confidence of its user while deployed in the field.

Here is the link to download the new v2.0 firmware.

NETSCOUT – Nuthin’ But a G(2) Thang

A few weeks ago at Mobility Field Day 2 I was afforded the opportunity to listen to a presentation from the fine people of NETSCOUT (all capitals because that is how Kendall Hershey told me it should be).  It was somewhat of a reunion for Brennan, Rob, and myself as we had established a relationship with NETSCOUT and their Social Media Manager, Kendall Hershey, at Cisco Live 2016 (shameless blog plug) .  It was great to see her again as well as take a deeper dive into the NETSCOUT product line, especially the AirCheck G2.

Chris Hinsz, NETSCOUT Product Manager, was the main presenter and he gave a nice overview of the NETSCOUT product line, more specifically the beloved AirCheck G2.  Many of us WLAN professionals use the AirCheck G2 at our day jobs and have come to love the simple yet powerful tool.  Chris went on to offer a closer look into what makes the AirCheck G2 so great as well as some lesser known tips and tricks.  Check out the presentation here.

Chris also gave us a quick demo of the Link-Live dashboard.  The Link-Live dashboard is a clean, easy to read area where you can collect the information that your various NETSCOUT tools gather.  I have had the opportunity to use the Link-Live dashboard with my LinkSprinters for some time and I appreciate the simple layout.  I can quickly get the information I need with a quick glance.  The dashboard organizes your tests into a table and allows you to make annotations, as well as create reports from the collected data.  NETSCOUT has definitely spent some time refining the layout making it easy to get the information you need from your test equipment.

I have been drooling over the AirCheck G2 since it was released.  We recently purchased one for work so I have only recently had the opportunity to use it on a regular basis.  I love the features of the G2 especially the touchscreen and well laid out menus.  The testing features are straight forward.  The G2 is hands down the first device we go to when we get called out for wireless issues.  The G2 saves us a significant amount of time troubleshooting.  Before the G2, troubleshooting wireless issues took much longer.  These handheld testers bring you to a solution much faster with the information that they supply.  I personally own the G2’s predecessor, the **Fluke AirCheck.  The original AirCheck is still very useful to me because it is able to extract a Meru/Fortinet/FortiRu AP ID out of a beacon’s information elements.  This makes it very easy for me to identify an AP that is a member of a Virtual Cell (virtual BSSID).  I still love my original AirCheck for this reason, but mostly because Kendall Hershey gave it to me.  I am told that they will look into adding the FortiRu information element to the G2 in the near future.

The AirCheck G2 has been, and continues to be, a staple in the WLAN professional’s bag of tools.  The NETSCOUT product line is built on a solid platform and is sure to deliver for the foreseeable future.  Anyone who uses a G2 will let you know how much it enhances their troubleshooting experience.  Issues that may have previously taken a few hours to figure out are easily diagnosed in a much shorter time period.  NETSCOUT is another one of those companies who I hold near and dear to my heart because they listen to their customers. I am looking forward to what NETSCOUT has coming in the future.

Through the Mist; Predictable, Reliable, and Measurable Wifi from Mist Systems

I recently had the opportunity to listen to a presentation from Mist Systems at Mobility Field Day 2 in San Jose.  At first glance/listen Mist might sound like just another controller-less “cloud” wifi solution that touts a shiny dashboard and user analytics.  They even toss around trendy new buzzwords such as “AI” and “machine learning.”  I was pleasantly surprised to find out that they are much more than that!

Mist is relatively new to the wifi game but their short lived heritage is backed by staff who have worked for the likes of Cisco, Motorola, Symbol, Airespace, Zebra, and Ubiquiti to name a few.  As you can tell their staff are seasoned professionals that have worked with companies with a very solid track record.  With a list of leaders like this I was confident they would be able to do wireless well, but I was still curious what would differentiate them from other offerings.  It didn’t take long to realize their pedigree and vision, when put together, sound as if they can break through the often “cloudy” (pun intended) traditional stalwarts.  Their current customer base is impressive, including several very large organizations that span several different verticals.

After a few moments into the introduction given by Jeff Aaron, you realize that Mist isn’t just another controller-less wifi company.  Jeff pointed out that Mist has two main objectives:

  • Bring wifi into the modern smart device era by:
    • giving data that allows an engineer to be proactive
    • providing predictive recommendations
    • allowing better visibility into the user experience
      • not traditional network visibility, but focus on user experience
    • making wifi more predictable, reliable, and measurable
  • Expand wireless.  Make wifi work for you.  Wireless as a Service
    • in addition to wifi, providing an indoor personalized location based experience
    • combining wifi and BLE into one platform

You might think that others are doing very similar things but Mist was the first to implement AI and machine learning.  Lee Badman, one of my co-horts at MFD, said it best when he said “Mist is the real deal when it comes to Machine Learning, etc- where the message feels forced with other vendors.”

Next to speak was Bob Friday.  Bob has a rich history of providing location based services in the wireless environment.  Bob was co-founder of Airespace, a wireless networking company who was the first to offer integrated location based services in their products.  Bob went on to explain that wireless has transitioned from just providing wifi into an “end to end” service. Bob made it very clear that the Mist location services were built from the ground up and that it wasn’t just a “BLE laid on wifi” afterthought.

One of the coolest things I got from Bob is that Mist actually employs data scientists to analyze the data that is collected.  He said that Mist has Particle Physicists and professors (you know, people who are actually good at sifting through data) going through and helping with design of the Mist product.  We have all seen a nice dashboard that is spewing data all over the place.  The data may have a nice presentation but is often to much or to little, and then all wrapped up in a pretty box.  It is clear that Mist wants the data to be clear and easy to read, as well as useful.

Mist really seems to be ahead of the game with their vBLE location services.  It didn’t take me long to realize that there are many use cases spanning several verticals for virtual beacons.  App developers can use these virtual beacons to interact with applications designed for all sorts of devices.  Applications can use location data to relay relevant information to the device owner based on the location of the device.  Some examples include way-finding at your favorite ball park or sending offers or discounts to a customer when they are near a particular product in a retail store.

Mist’s dynamic packet capture is something I think is an absolute game changer.  Mist is able to leverage it’s services to detect problems on the wireless network and then collect a packet capture in real-time.  We have all been called out to troubleshoot problems at one time or another and by the time we get to the site, the problem has disappeared or changed.  When Mist detects an issue, it automatically starts a packet capture.  Being able to gather packets immediately when a problem is detected can potentially solve a problem in a matter of minutes where in the past it may have taken several hours.

One other notable feature is Mist’s ability to give meaningful and measurable data that makes it easy to show whether or not Service Level Expectations (SLEs) are being met.  Based on the information given in the dashboard it is easy to tell which clients are having trouble connecting or are failing to connect.  Being able to evaluate access point health, coverage, capacity, and throughput are also a major advantage for any wifi engineer and are all easily found in the dashboard.

Overall, I thought Mist was very impressive.  They are doing things with their product that can make life as a wifi engineer easier.  There is no better judge of a wireless network than the actual user experience and it is obvious that is where Mist is focusing their efforts.  I am familiar with BLE but overall I am generally “green” and have lots to learn.  What I do understand about Mist’s vBLE is that it has potential to be very powerful.  I plan on digging a little deeper into vBLE when I get an opportunity.  Having listened to Jeff Aaron, Bob Friday, and Sudheer Matta, I can tell they are confident and passionate about Mist.  I am hoping to hear  more from them in the near future.  For now, please watch their presentation from Mobility Field Day 2.   There is a lot more impressive information in their presentation. I hope you find Mist as intriguing as I did.

Mobility Field Day 2

The excitement for MFD2 has been building for awhile now and I can tell you we are in store for a great couple of days.  I have been looking forward to this event since I accepted the invitation to be a delegate a couple of months ago.  After coming together for dinner tonight as our first time as a group, I am even more excited for all that is in store.

Here is the lineup:

Mist Systems – July 25, 2017 at 10:00 – 12:00 PST

I have had a chance to play around with one of Mist’s APs over the past couple weeks and I found it to be very intuitive and easy to set up.  It took no time at all to get an SSID on the air and clients connected.  The available data on the dashboard is very helpful/useful.  I am looking forward to getting a deeper dive into the BLE features of the device.

Mojo Networks – July 25, 2017 at 2:00 – 4:00 PST

Mojo Networks, formerly AirTight, has gone through several changes over the last couple years.  They have changed their direction and I am looking forward to hearing more about their plans going forward.  They had an excellent presentation at WirelessLAN Professionals conference this past February.

Cape Networks – July 26, 2017 at 9:00 – 10:00 PST

Cape is a company that I am not real familiar with yet and I am very interested to see what they have lined up.  I did see their presentation at WLPC but haven’t had a chance to work with their gear yet.

Nyansa – July 26, 2017 at 10:30 – 12:30

Another company that I am really looking forward  to hearing more from is Nyansa.  From what I have seen, they are able to take wireless client data and present it to an engineer in an easy to read format to get a better understanding of what is actually going on in the wireless network.  You can find their presentation from WLPC here.

Netscout – July 26, 2017 at 2:00 – 4:00 PST

The AirCheck G2 is our go to tool in the field when a wireless problem is reported at work.  I am excited to hear what they have in the pipeline for the future.  I am also pumped that we get to see our good friend Kendall Hershey.  A couple of us had the pleasure of meeting and hanging out with her at Cisco Live 2016.  Her and I both missed this year’s Cisco Live so it will be cool to see her again.

Being able to watch and listen to presenters at previous Wireless/Mobility Fields days and interact with the delegates was something I looking forward to.  With this being my first MFD, I would be lying if I said I wasn’t a bit nervous but I am with a great group of professionals so I am sure it will go great!  I am very excited for the next two days as they will be packed from the beginning of the day until the end with all kinds of great information and maybe some surprises.

Please feel free to follow along on the Mobility Field Day page here.

Please also feel free to interact with me or any of the other delegates listed in the above link.  Interacting with the delegates was almost as fun as listening to the presenters in my past experiences.  If you have any questions you would like to see asked of the presenters, feel free to reach out to any of us delegates via Twitter.  Make sure to also use the hashtag #MFD2.

In the weeks to come I will be releasing blog posts about the presentations so make sure to check those out when they are released.
