Ekahau Retools For The Future

As a long-time Ekahau user (pretty sure I was one of the first few American customers way back when), I’ve gotten used to continuous improvement and evolution from Ekahau Site Survey (ESS) suite of tools. There have always been new features right around the corner, and the company has been perhaps the best I’ve ever seen at gathering and acting on user feedback. It’s been a great run. In the recent past, the hot-selling Sidekick provided a unique new dimension to the survey and spectrum analysis processes, and the Ekahau company was purchased by Ookla/Ziff-Davis. Both of those developments are pivotal to what comes next for Ekahau.

And what comes next is called Ekahau Connect.

Ekahau Connect

There’s  A LOT here to talk about, starting with ESS getting rebadged as Ekahau Pro, now compatible with both Windows and Mac operating systems. (If you are new to the world of WLAN support, trust me that Mac is a far-better tool platform than Windows- and I am unabashedly NOT an Apple lover.)

Then there is Sidekick’s expanded capabilities- including wireless packet capture leveraging Sidekick’s dual radios (yay!) and the ability to interface with the iPad as a survey platform. This is a pretty big deal, and the light physical weight of the iPad makes for easier, more comfortable surveys.

And… Ekahau does a little catch-up with it’s introduction of Ekahau Cloud. This is one extremely valuable capability that competitor iBwave has had for some time, as I wrote about here. Having used iBwave’s cloud tools, I can assure you that Ekahau’s customers who work in teams are going to love it and there is no doubt that the cloud expertise behind Ookla has some impact here.

And is if this all wasn’t enough for Ekahau Nation, feast your eyes on another new benefit- Ekahau Connect components working together to identify, classify, and locate interferers:

I have been fortunate in that I have been a beta tester for Ekahau’s latest. At the same time, a couple of serious “life happens” events have kept me from being a good beta tester. So for real-world first-hand perspective, I’ll hand you to two two of my favorite people on the No Strings Attached podcast.You’ll be in good hands with Sam and Blake.

 

 

Move Wi-Fi Explorer From Old Mac to New

The Mac laptop that hosts my excellent Wi-Fi Explorer Pro application has seen better days. It’s time to put this awesome WLAN support tool from Adrian Granados on a newer Mac, but I was a bit stymied when I first tried to figure out how. I envisioned some sort of license key transfer, but just wasn’t seeing it… I queried my best WLAN community homies, and dropped a line to Adrian himself. Before a meaningful response came back, I figured it out, and so thought I’d share.

It’s easy-peasy, once you see it.

1. De-Activate Wi-Fi Explorer Pro on Old Machine, under “Help”

Deactivate WFE

2. Download, install trial version of Wi-Fi Explorer Pro on new machine

3. Fire up the program, find these options:

Activate WFE

4. Dig out your license file- search on “Paddle license” in your email:

WFE License

5. Enter the license key and activate the program. 

Like I said… easy.

DON’T FORGET ABOUT THE DISCOUNTS ADRIAN GRANADOS HAS OFFERED FOR NEW PURCHASES OF WiFi Explorer PRODUCTS!

  • Educational customers get 50% off. Details are here.
  • Everyone who attended WLPC Conference in February ’19 was given a card for a 30% discount on WiFi Explorer Pro. You need the code from the card, and the discount is available until 3/31/19.

Now you now.

What Wi-Fi Tools are MetaGeek and Oscium Cooking Up Together?

As I write this, the 2018 Wi-Fi Tek Conference is going on in San Diego. I’m not attending (mostly because Boardman is there) but I am listening to various comments being made about the event goings on though the many channels that all of us WLAN types keep each other updated on. There’s a lot of good chatter, and I wish my CWNP family the best of luck with conference (I am on the CWNE Advisory Board you know… I run in those circles.) One little nugget from Twitter caught my attention, in particular.

metageek-oscium

I happen to have products from each company, and both are among my favorite tools when it comes to WLAN support. After the tweet, I went and found MetaGeek’s own announcement on the new partnership, which you can read about here.

Oscium Logo

Now, betwixt you and I- neither company has been especially active of late as far as getting new tools (or even updates to existing tools) out in front of us loyal customers, and I’m glad to see hope of that changing.

I’ve written about Oscium in the past and still think their WiPry 5x is one of the slicker spectrum analyzers out there for those of us that have familiarity with real lab-grade spec ans. I’ve also covered MetaGeek through the years, and was fortunate enough to see their presentations at multiple Tech Field Day events. You won’t find nicer folks than MetaGeek’s current and past employees… must be a Boise thing.

Now back to that announcement of a partnership between MetaGeek and Oscium. We still don’t know a lot, but this is pivotal from the MetaGeek blog:

MetaGeek plans to partner with Oscium for additional hardware offerings moving forward as part of the company’s shift to focus on the software side of their industry-leading Wi-Fi analytics solutions.

Just as Ekahau has realized, you can only take legacy USB adapters so far in the world of 802.11ac (and soon .11ax) wireless support tools. MetaGeek has had profound impact on the WLAN industry with their USB-based stuff, but it also became stunted despite having really effective software pairings (like Channelyzer, InSSIDer, and the fantastic Eye P.A.). Oscium has figured out how to leverage well a range of mobile devices (both Android and Apple) and their latest connectors for use as Wi-Fi support specialty tools.

I smell synergy, baby…

I have seen nothing in beta as for as this story line goes. I’ve had no conversations of late with either MetaGeek or Oscium, so I really can’t give you anything beyond speculation and hope that good things are coming, but I also have a lot of faith in both companies.

I’m looking forward to the end of the year, and whatever announcements these two toolmakers are working on.

Say Hello to Ooklahau

ooklahau 3 If you’ve been in the business of professional wireless networking for any amount of time, you no doubt have at least a familiarization with Ekahau. For many of us, our networks would not be what they are today if it weren’t for the long-running design and survey reliability and excellence baked into Ekahau’s magic. I’ve been a customer for somewhere around 15 years, and the Ekahau experience with both predictive designs and active surveys has only gotten better with each release. The addition of Sidekick to the ESS suite was a game-changer, and the future looks bright for this Finnish company who also happens to be well-connected to their end users, open to ideas for product improvements, and… well, downright fun to work with.

ooklahau 1Then there’s Ookla- the Seattle-based speedtest.net people that pretty much anybody and everybody on the planet with a connected to device has likely used at some point. They have a huge end-user facing presence with their speedtest apps, but also an impressive global presence that services enterprise customers as well. Ookla started in 2006, and has been growing their cloud-based service offerings and brand -recognition ever since.

Let’s not be coy… you know where this is going. Despite my cheesy logo play, a name change IS NOT imminent to either company. But Ekahau has been acquired by Ookla, as you can read about here on Ekahau’s own blog. I did get a chance to talk with my pal Jussi Kiviniemi (Senior VP for Solution Strategy and Customer Experience) at Ekahau about the news just moments before writing this.

Customers can expect Ekahau to stay largely the same operationally for the foreseeable future, but behind the scenes the global human and technical resources of Ookla are going to mean good things over time. Jussi was practically beaming, even over the phone. This is going to make for really interesting days ahead for wireless and network performance testing for sure, and could enable some pretty fascinating things on the design side when the cloud aspect is figured in.

Congrats, Ekahau! Well done, and well-deserved.

Catching Up With NETSCOUT at MFD3, Big News, and “Body Fade” Explained

Touching Base at Mobility Field Day 3

Everybody’s favorite handheld network tool tester provided updates on their G2 and AirMagnet tools at Mobility Field Day 3. NETSCOUT hosted those of us in attendance at their San Jose office, while simultaneously live-streaming to a lot of interested folks out on the interwebs. We heard about product evolutions coming to the AirCheck G2, the LinkRunner G2, the very handy Link-Live web service, and a little bit on the AirMagnet product line. The G2 improvements are incremental, well-designed, and show that NETSCOUT is not letting grass grow under it’s flagship testers. The AirMagnet brief sounded a bit apologist and fairly thin, but also not unexpected given that the line has gone almost stagnant for long periods of time.

You can watch the presentations for yourself here.

Big News

This one took us by surprise… It’s a bit weird to find out only a couple of days after being at Netscout’s offices that the very product line we were discussing has been sold off to Nacho Libre… or is it StoneCalibre? Whatever… it just feels funky to those of us who know and love our AirCheck and LinkRunner products.  What goes in this move?

  • LinkSprinter
  • LinkRunner (AT & G2)
  • AirCheck
  • OneTouch AT
  • AirMagnet Mobile (Spectrum, Survey, Planner, Wi-Fi analyzer)

Hopefully whoever this new backer is does not mess with all that’s good in the toolbox, and either breathes new life into AirMagnet or retires it. Read about the acquisition here.

What the Heck is Body Fade?

bodyfade

During the MFD sessions, we heard about several improvements- including refinements to the AirCheck G2’s Locator Tool. I tweeted out my recent success with the tool, and suggested that anyone using become familiar with “body fade” as technique to make the locator tool even more effective.

A couple of folks gave a thumbs-up, retweet, or similar affirmation, but one fellow emailed me to ask “what are you talking about with body fade?”  Let’s talk about that just a little, using a real-world case from my adventures in G2 Land.

The notion of body fade comes into play in any situation where you have a hand-held receiver in your hand (like the AirCheck G2 or a small ham radio with a bandscope display) and are trying to locate the origin of a signal of interest. By putting my body- including my rock-hard abs- between the signal and the tester, you can make the signal strength drop enough to notice. That means that the signal is somewhere behind you… do this enough times, and you get a really good sense of where to go look for the device faster than just running around staring at the dancing signal needle.

In my example, we see this rascally rogue running rebellious somewhere in another part of my building:
locate5By golly, that’s not one of mine. We gotta find the interloper and teach him or her some manners, I tellya. I fire up the AirCheck G2, invoke the locate option, and see what I see in my office.
Locate4
Not so impressive yet. We have a fairly weak signal somewhere. But how to get started on this foxhunt? BODY FADE to the rescue. I hold the G2 in front of my Adonis-like physique and slowly turn (the slowly part is important)… until I see a 3-4 dBm DROP in signal strength. This is my body inducing loss to the signal and thus showing you where to turn around and what direction to walk towards…

OK… so I start walking, and I’m making progress. The signal is getting stronger, and I use body fade to help further refine my path. But alas- I hit an obstacle! Once I get to THIS signal strength, I’m bamboozled:

Locate 3Nothing I can do from the spot of this reading with body fade changes the signal strength at all. If I walk away from the spot in any direction, the signal drops, but it is strong in this one spot. Yet the rogue is absolutely not there (in a hallway). What gives?

Remember that we’re dealing with signaling in three dimensions. When body fade at X-marks-the-spot yields no changes in signal strength, it means it’s time to go upstairs or down. In my case, there is no downstairs, so up I went. I picked up the trail, and soon hit the jackpot:
locate2
This was screen-shotted in the doorway of the office where the offending device was found. After roughing up both the rogue router and the gent who dared to plug it in, balance was restored to The Force.

Body fade is pivotal to some really neat radio hobbies- like this one.

 

 

 

 

Figuring Out What Bothers Me About Wi-Fi and “Analytics”

I’ve been to the well, my friends. And I have drank the water. 

I was most fortunate in being a participant in the by-invitation Mobility Field Day 3 event, this past week. Few events get you this close to so many primary WLAN industry companies and their technical big-guns, on such an intimate level and on their own turf. For months leading up to MFD3, something  has been bothering me about the discreet topic of “analytics” as collectively presented by the industry- but I haven’t been able to nail down my unease until this past week.

And with the help of an email I received on the trip back east after Mobility Field Day was over.

Email Subject Line: fixing the wifi sucks problem

That was the subject in the email, sent by an employee of one of the companies that presented on their analytics solution at MFD3 (Nyansa, Cisco, Aruba Networks, Fortinet, and Mist Systems all presented on their own analytics platforms). The sender of this email knew enough about me to do a little ego stroking, but not enough to know that only a matter of hours earlier I was interacting with his company’s top folks, or that I’ve already had an extensive eval with the product he’s pitching at my own site. No matter… a polite “no thanks” and I was on my way. But his email did ring a bell in my brain, and for that I owe this person a thank you.

The subject line in that email set several dominoes of realization falling for me. For example-  at least some in the WLAN industry are working hard to plant seeds in our minds that “your WLAN sucks. You NEED us.” Once that hook is set, their work in pushing the fruits of their labor gets easier. The problem is, all of our networks don’t suck. Why? These are just some of the reasons:

  • Many of our wireless networks are well-designed by trained professionals
  • Those trained professionals often have a lot of experience, and wide-ranging portfolios of successful examples of their work
  • Many of our WLAN environments are well-instrumented with vendor-provided NMS systems, monitoring systems like Solar Winds and AKIPS, and log everything under the sun to syslog power-houses like Splunk
  • We often have strong operational policies that help keep wireless operations humming right
  • We use a wealth of metrics to monitor client satisfaction (and dis-satisfaction)

To put it another way: we’re not all just bumbling along like chuckleheads waiting for some Analytics Wizard in a Can to come along and scrape the dumbness off of our asses.

In all fairness, that’s not a global message that ALL vendors are conveying.  But it does make you do a double-take when you consider that a whole bunch of data science has gone into popping up a window that identifies a client that likely needs a driver update, when those of us who have been around awhile know how to identify a client that needs a driver update by alternate means.  Sure, “analytics” does a lot more, but it all comes as a trade-off (I’ll get into that in a minute) and can still leave you short on your biggest issues.

Like in my world, where the SINGLE BIGGEST problem since 2006, hands-down and frequently catastrophic, has been the buggy nature of my WLAN vendor’s code. Yet this vendor’s new analytics do nothing to identify when one of it’s own bugs has come to call. That intelligence would be a lot more useful than some of the other stuff “analytics” wants to show.

Trade-Offs Aplenty

I’m probably too deep into this article to say “I’m really not trying to be negative…” but I’ll hazard that offering anyways. Sitting in the conference rooms of Silicon Valley and hearing from many of the industry’s finest Analytics product’s management teams is impressive and its obvious that each believes passionately in their solutions. I’m not panning concepts like AI, machine learning, data mining, etc as being un-useful as I’d be an idiot to do so. But there is a lot of nuance to the whole paradigm to consider:

  • Money spent on analytics solutions is money diverted from elsewhere in the budget
  • Another information-rich dashboard to pour through takes time away from other taskings
  • Much of the information presented won’t be actionable, and you likely could have found it in tools you already have (depending on what tools you have)
  • Unlike RADIUS/NAC, DHCP/DNS, and other critical services, you don’t NEED Analytics. If you are so bad off that you do, you may want to audit who is doing your network and how

Despite being a bit on the pissy side here, I actually believe that any of the Analytics systems I saw this week could bring value to environments where they are used, in an “accessory” role.  My main concerns:

  • Price and recurrent revenue models for something that is essentially an accessory
  • How well these platforms scale in large, complicated environments
  • False alarms, excessive notifications for non-actionable events and factors
  • Being marketed at helpdesk environments where Tier 1 support staff have zero clue how to digest the alerts and everything becomes yet another frivolous trouble ticket
  •  That a vendor may re-tool their overall WLAN product line and architecture so that Analytics is no longer an accessory but a mandatory part of operations- at a fat price
  • Dollars spent on big analytics solutions might be better allocated to network design skills,  beefy syslog environments, or to writing RFPs to replace your current WLAN pain points once and for all
  • If 3rd party analytics have a place in an industry where each WLAN vendor is developing their own

If all of that could be reconciled to my liking, much of my skepticism would boil off. I will say after this last week at MFD3, both Aruba and Fortinet did a good job of conveying that analytics plays a support role, and that it’s not the spotlight technology in a network environment.

Have a look for yourself at Arista,  Aruba, Cisco, Fortinet, Mist and Nyansa telling their analytics stories, linked to from the MFD3 website.

Thanks for reading.

A Little Quiet Please- The Jabra Evolve 75

Jabra 75 EvolveFew things are more annoying when you’re troubleshooting in a noisy environment while trying to work with technical support or a coworker over the phone and you can’t hear them (or they can’t hear you). There’s usually enough stress in play to begin with, and having to repeat yourself and say “what? I just can’t hear you…” over the exhaust fans of network equipment in packed racks only makes it worse. Enter the Jabra Evolve 75.

Quiet Down!

Marketed as “the best wireless headset for concentration in the open office”, the Evolve 75 from Jabra is impressive for a number of reasons.

I don’t work in an open office environment so I can’t validate Jabra’s claim in that regard, but I can tell you that the Evolve 75 impresses in the noisy data center and telecommunications closets frequented by network technicians and administrators. I recently took an evaluation unit for a spin, and the timing was perfect for a real-world test under extremely loud background noise conditions. Not only could I hear the support engineer on the other end perfectly, but he also said my audio was clear despite the Evolve 75 mic being  inches away from blowing server fans. It’s hard to ask for more than that, but there is more to talk about.

Classy

Jabra has always made fairly elegant Bluetooth headsets for cellphones, in my experience. This was my first outing with a professional grade Jabra product, and it blew the doors off of other headsets I’ve tried to use in similarly noisy situations. The Evolve 75 is fairly light, but substantive. It feels good on my big head, and the mic raises and lowers smoothly, and in both positions is unobtrusive. The overall look and feel whether it’s on your head or in it’s beefy charging cradle is one of quality.

Functional

I’m finding that the Evolve 75 has really, really good battery life for my usage patterns- but I also do not wear it as long as a call-center person or the like might. The ANC (Active Noise Cancellation) functionality works like a dream, and these may be the absolute quietest phones I’ve ever used. I manipulated the volume buttons and mute functions on WebEx, Skype, and simple phone call without having to fumble around, and it doesn’t take long to feel at a disadvantage when you take a call without the benefit of this headset.

I also made use of the unit’s ability to pair with two Bluetooth devices at once, which proves handy more often than you might think. When paired simultaneously to my computer and my smartphone, the new-found mobility and seamless transitioning between the two was just a joy to experience. I’m not one to gush, but I kinda fell in love the Evolve 75 and don’t mind saying so.

Nice Bonuses

I’m not sure that I qualify as an audiophile after all the beating my ears took working around loud fighter jets in my Air Force days, but I do enjoy music and the occasional podcast. Jabra makes both activities more enjoyable with the sound quality, volume, and purity that the Evolve 75 delivers. It also comes with a really nice travel case.

The only downside I see with the Evolve 75 is that it’s one of those really, really nice tools  that you miss greatly when you don’t have it.
