All about DART
Yes, I’m writing a blog post on a connector. Just a connector. If you’re like me, you can appreciate the little things in life. This is one of those times that something little snuck past me and it wasn’t until now that I’m starting to fully appreciate it’s impact and importance. When Cisco launched their 2800/3800 APs, dual 5GHz was certainly at the top of the list of the most talked about features (see #MFD session here!). This came with some caveats (as all new features do) and using a separate set of antennas for the second 5GHz radio was the biggest. This is handled on the internal antenna models with an in-built extra set of antennas, but on the external antenna models, this presented a bit of a challenge. In the wide world of antenna connectors, in the Wi-Fi space, we commonly deal with RP-SMA, RP-TNC, and N-type connectors depending on your vendor and the deployment type. In the Cisco world, that’s RP-TNC for indoor APs. With a single, 4 element antenna today, that’s four connectors (or four, single element antennas). With two antennas, that drives the number of antenna connectors up to a whopping 8 cables you’re looking to have coming out of your AP! 8 cables, 8 connectors, it gets messy quick. Enter the DART connector:
Inconspicuously located on the side of the AP, behind a little door, the new DART connector reveals itself in a complex looking array of pins and connectors in a tight external facing form factor. Here’s the interesting part though, this isn’t a new connector! In fact, it’s been shipping to the public for a little bit now in the form of the Cisco Hyperlocation module and antenna!
So, that’s all great and all, but what’s really *in* the DART connector? DART stands for Digital Analog Radio Termination and it does all of those wonderful things. Firstly, the analog antenna connectors that we use (so we don’t have 8 RP-TNC ports on our AP) are the 4 larger pins across the bottom of the connector.
When we use the DART to RP-TNC pig tail for backwards compatibility with shipping antennas, these are the connectors that map directly to the 4 RP-TNC connectors. In short, these are the 4 analog ports that carry the actual analog signal through the connector.
Which leave us with the extra 16 pins. Those are the ‘Digital’ piece of the DART connector and can be used for a variety of uses. Initially, this is used to identify the type of cable that is attached to the DART connector. For example, in the Hyperlocation module, this shows up on the AP details:
For the DART to RP-TNC connector, this is in the form of a simple resistor that maps two of the pins back to each other:
It’s easy to see that there’s quite a bit of left over functionality that could be used in a connector of this type. Today if we use very high gain antennas we have to have multiple models of APs (see the 3602p and 3702p). If we could identify the gain of the antenna by way of an automated mechanism, we could have the AP auto adjust itself to not exceed EIRP. Another potential use case is DART native versions of our existing antennas in a simple to use connector. Imagine not having to screw on connectors anymore! With a quick-connect antenna mechanism that auto-IDs the antenna capabilities to the AP, this could certainly be the new connector of choice for external antennas in the future!

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.
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 Link-Live.com 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.

Tivoli Audio reveals PAL BT Go illuminated portable radio
Now now, let us not pooh-pooh the good old radio, shall we? After all, this is what kept our forefathers entertained for hours on end in the past, and it does look as though this is a device that is not going to go extinct anytime soon. After all, you might come up with a playlist of your choice, carefully curated to cater to your whimsical and eclectic musical taste, but there is just something sterile about a playlist. Yeah, you guessed it correctly – there is no human interaction or element in it, and this is where the radio DJ helps to brighten up your day. So, if you are in the market for a portable radio, how about going retro with Tivoli Audio’s PAL BT Go?
This PAL BT Go will be very, very different from the other models, since this is a limited edition portable Bluetooth radio which is not only fun, but functional as well. The PAL BT Glo will boast of a clear frosted LED illuminated version, where such a classic product will now arrive adorned with LED lights, and these LED lights will be easily adjustable in order to set the right kind of mood. Not only that, Tivoli Audio has decided to throw in a leather carry strap in order to ensure that the unit ends up more portable than ever before.
As its name suggests, this particular batch of PAL BT Glo will be a limited edition one, where there will only be 5,000 of such puppies rolling off the production lines, and needless to say, each of these units will be individually numbered so that you can be part of something special.
The integrated battery is capable of delivering up to 10 hours of non-stop playback, and one will be able to switch it on and wirelessly to connect via Bluetooth in order to start playing without having to go through a complicated setup process. Other features include an AM/FM analog tuner, Bluetooth streaming, and Auxiliary input, and all of it will retail for $199.99 a pop.
