How to plan a Wi-Fi deployment: Performing a predictive site survey

This blog is the second in a 3-part series summarizing these initial steps up to the point where you have gathered network needs and assessed RF environment conditions. After gathering information about the goals and expected uses of the wireless network, use a planning tool, such as the Aerohive...

How to plan a Wi-Fi deployment: Coverage and Capacity

When planning to deploy a wireless network, you must first determine the number of clients you expect to serve, the type of traffic you expect on the network, the amount of throughput you want the network to provide, and the number of access points you need and where to mount them for optimal...

Investing in Beamforming: Is it worth it?

As everybody who is willing to put up with my descriptions of minutely technical features in Wi-Fi no doubt already knows, one of the key constraints on wireless LANs is that the data rate that can be achieved is loosely dependent on your range from the access point.   There are a number of subtle...

Did the FCC really limit 802.11ac beamforming?

When talking about 802.11ac, beamforming is a common topic of conversation. Yes, it was first standardized back in the 802.11n days, but it was never widely implemented. Significant work was devoted to making beamforming simpler to implement in silicon in 802.11ac, which I expect will pay off...

802.11n & 802.11ac Modulation and Coding Scheme (MCS) Tool

Our friends at WiTS (Wireless Training & Solutions) have done it again – another awesome HTML5 reference tool! This time, an interactive MCS tool. Click an MCS rate or modulation type once to see just those items, and click it again to return to the main screen. This is helpful when you want to know...

Wi-Fi Channel Simulator 2.0

Well, you knew it had to happen. The makers of Wi-Fi Channel Simulator have brought us a 2.0 version. Yes, now with 80 and 160 MHz wide channels and in HTML5 for all of you Apple-lovin’, iPad-packin’, Flash-hatin’ geeks out there. Oh, by the way, that describes me too. SWEET!           (For a...

Why 802.11ac is scary

Halloween is right around the corner, and one thing I learned from last month’s Wireless Field Day is that 802.11ac is apparently scary. Quite a few of the delegates asked me why the industry appears to be scared of 802.11ac. I guess we’re just weird at Aerohive because we love 802.11ac.Why? Several...

Here’s Your Sign

Meraki has taken Wi-Fi infrastructure to a whole new level of ridiculous with the “Split Controller.” My inner sarcastic comedian couldn’t keep quiet about this.Meraki devices (APs, switches, and routers) connect to their cloud management platform for management and control. To be absolutely clear,...

Architecture Still Matters

It’s been exactly 3 years since I started at Aerohive, and I’m pretty dang sure I mentioned that every Wi-Fi infrastructure company would be forced to “copy Aerohive or die.” Wait for it … wait for it… I TOLD YOU SO! Ah … that feels nice … OK, I’m over it. So … moving on.  Here we are, after all...

Wi-Fi Back to Basics – 2.4 GHz Channel Planning

Because I have been in the Wi-Fi industry for 12+ years, I sometimes forget that the technology is still a young technology. To this day I find that many Aerohive customers and even some Aerohive partners are just getting introduced to the basic concepts of 802.11 wireless networking. Therefore, I...
