AirCheck G2 gets a v2

It’s no secret that I’m a fan of the Netscout AirCheck G2 and have been since before it’s release. I’m happy to see that today they announced the version 2 of the firmware for the AirCheck G2 which brings some pretty neat features to the product. The official page goes into greater detail on the updates, but the two I’m most impressed with are the new interferers page and the integration of iPerf testing for the unit.

The interference detection is a nice to have feature for those field teams that need an initial look at the non-Wi-Fi devices in the air around them. It’s leveraging the integrated WLAN radio for spectrum analysis so it’s not perfect, but it readily enough identified several of the more common interference devices around me (bluetooth and microwave ovens). In addition to identifying the interference, the ‘locate’ functionality that you’ve come to expect with the AirCheck also works with the source of interference. In my testing, I was able to demonstrate that moving away from an active microwave oven did indeed show a corresponding drop in detected signal strength. Let’s be fair, it’s not a fully blown FFT based Spectrum Analyzer, but in a pinch, and for common items, it’s far more insight than we’ve ever had in a a handheld tester.

The iPerf server is another interesting new feature – not only for the AirCheck side of the equation, but for the far side tester as well. The newly announced Test Accessory from Netscout is reminiscent of the LinkSprinter products – handheld, portable, battery or PoE powered, and cloud enabled tester.


The Test Accessory

This integrates quite nicely with the v2 firmware with the new iPerf test option once you connect to your SSID. The nice bit is that this removes most all of the headache of doing iPerf testing – configuring the server and figuring out what it’s IP address is. You can plug the Test Accessory into your network anywhere and it will phone home to the Link-Live service. The AirCheck will query the service and automatically populate the testers IP address for your test. This makes a very simple to use throughput tester that’s easy to carry and accessible to everyone. If you don’t have a Test Accessory or if you’re comfortable with iPerf testing, you can also just use the AirCheck as a standard iPerf endpoint, so you’re covered either way you want to go here – with a stock, static internal iPerf tester or with a field accessible, cloud enabled tester that goes anywhere.

These features take an already dead-useful testing tool and expand it’s role for the Wireless LAN deployer to go beyond just ‘is it up’ testing. With the ability to now detect a number of interferers and do actual throughput testing of a Wi-Fi network, the field implications are that your existing installation teams (or other G2 users) can more deeply validate the functionality of a network – and when things go wrong, have another level of insight that they previously did not have. I’m quite happy that Netscout is clearly investing in, not only the G2, but additional products that augment and expand it’s functionality. The G2 is an overbuilt hardware platform and it’s refreshing to see that Netscout is taking advantage of that extra horsepower. If you’re an AirCheck G2 user, you really need to go get the firmware update now. If you’re not an AirCheck G2 user, what are you waiting for?


NETSCOUT AirCheck G2 unleashed!

This blog post is part 1 of a multipart series on the new generation of Wi-Fi tools. There has been a dramatic evolution of the various tools that the WiFi professional uses over the past year or so . I wanted to take a moment and spell out my thoughts on the current state of tools in our industry.

First shown at the Wireless Field Day 1 in San Jose the Fluke AirCheck rapidly became the staple of the ‘serious’ WLAN troubleshooter. It made a huge splash and was immediately lauded for it’s easy straightforward to getting down to the serious data that you need to see when troubleshooting your wireless network. All of the heavy hitters in the industry have been talking about them since then and it’s almost unbelievable that it was just assumed that people would have them on anything but the most entry level of jobs. The platform had very few deficiencies overall and almost became part of the de-facto tool that you would be expected to know and use – almost like site survey software.

The G2

AirCheck G2 – The green is a nice touch!

It’s hard to think of something replacing the Fluke AirCheck but the inevitable has happened. There is and Application & Network Performance Management company called NETSCOUT recently acquired the Fluke team responsible for the AirCheck – which was in the midst of developing the next generation of the product. Launched late last month, the AirCheck G2 promises to best it’s predecessor in several areas. Head on over to the official announcement and keep a keen eye out for a quote or two from yours truly! 🙂



I was fortunate enough to be included early on in the development conversations of the AirCheck G2 and so like to believe that I helped shape in some small way the look, feel, and usability of the product as it exists today. From early on, there was a focus on the ‘gimme’ features such as inclusion of a color touchscreen. Other features didn’t develop till later on such as the built in ethernet port for wired testing in the field. Those of you that love the LinkSprinter functionality, this is aimed squarely at you! In fact, there is a laundry list of features that read like a who’s who of todays troubleshooting gear – 802.11ac support, long life battery, external antenna support, USB expansion ports, on screen keyboard and navigation menus, auto testing, and rapid boot & shutdown, just to name a few.

By far and away though, the feature that I’m most enamored with at the moment is the integration. Starting with an easy way to claim the devices online, a one stop shop for getting your software and updates, and of course, upload notifications of the testing you’ve just done – the ability to bring Organizational structure to such an outstanding troubleshooting tool really brings the product full circle. NETSCOUT has done a superb job of rolling functionality and usability into a cloud based product and included it with the product! This wraps up all of the auto-testing into an easy to use and store place for testing and validation. While this may seem like simple functionality, for an organization with multiple units in the field, this sort of automated cloud-rollup functionality is hands down one of the best features of the AirCheck – and that’s saying a lot!

If you haven’t had a chance to get your hands on an AirCheck or have been waiting for a refresh to make the product ‘perfect’, now is the time. You should go ask your VAR, NETSCOUT rep, or beg borrow or steal one to get some time under your belt with one. The simplicity of the product, ease of use, intuitive navigation, and ready access to some very in-depth and advanced data in a straightforward way to consume it.
