Ten years has validated my assertions (in 2008 and in 2009) that location services is the end game. Whether it’s used for asset tracking, people tracking, wayfinding, or even location-based access control, location services is the killer app of all time. How do I know? I cheated and read a little ahead in the Book. […]

There has been much misinformation and misunderstanding around so-called ghost frames. There is no frame type or subtype in the 802.11 standard called a ‘ghost frame’, but rather it’s a byproduct of frame reception that happens by way of 802.11 protocol design around 802.11 Basic Service Sets (BSSs). Before the ill-named concept of a ghost

While there are some technical reasons to be excited about the soon forthcoming 802.11ax (hereafter, just 11ax) technology, it has one big Achilles Heel that must be considered by any customer who is going to upgrade their 802.11ac Wave-1 or Wave-2 infrastructure to 11ax. >> >> >> Legacy Client Devices << << << Yep, that’s

There must be 10Gbps of Wi-Fi throughput hype out there, and I want to explain expected throughput for 11ac and 11ax WLANs in a way that is clear to everyone. First, we need to understand what can be expected on a 20MHz channel, given a standard assortment of client devices. Here’s a graphic from my
Back-to-back innovative product releases from Aerohive…hmmm. Who would’ve thought that they would re-enter the innovation game after a 5-year hiatus. Not me, but I must say that I’m very pleasantly surprised. I had almost written them off, but it looks like someone or something breathed new life into the company, and I’m glad to see

So much has been and will be said about the upcoming 802.11 PHY amendment called 802.11ax (hereafter just “11ax”) that I felt I needed to chime in to counteract some of the expected poor marketing. This blog is not about what 802.11ax is, but rather is about what 802.11ax is not. If you read the
My friend Keith Parsons and I are fond of saying, “It’s All About The People.” Because it is. People and relationships are what’s really important in life, but everyone (including me) loses sight of that as we get caught up in the hustle of daily life. Whether at home or at work, we run our

In each of my weekly classes, I do a full walk-through of the “Define, Design, Deploy, Diagnose (Validate/Optimize)” process. It’s never a surprise when most of the students are excited to see a documented, vendor-neutral walk-through of the process. I’m always asked for a copy of the flow chart (shown below) document so that the

Simply because it’s awesome, I thought I would write a blog about the AirCheck G2. It’s my favorite WiFi diagnostics tool, hands-down. It does so many things in such a small, rugged form factor that it’s impossible not to love. As soon as I first saw it, I knew NetScout had a winner – and

With client density continually on the rise, and more high-density use cases popping up all the time, it only makes sense to replace unused 2.4GHz radios with 5GHz radios in many deployment scenarios. As the 2.4GHz band becomes more crowded with WiFi and non-WiFi devices, the pressure relief valve (so to speak) will be adding
