Channel Bonding Caveats – Over and Above Spectrum Hogging


Popular literature on 802.11ac describes 40 MHz and 80 MHz operation (channel bonding) as doubling and quadrupling of the data rate, respectively. Every time I saw that mentioned, the following question came to my mind.

When radio transmits over 40 MHz (or 80 MHz) channel, is the total transmit power proportionally increased over 20 MHz to maintain the SNR (signal to noise ratio)? And, how is the data rate multiple with channel bonding distributed over the cell?

This question nagged me like a little stone in the shoe that is impossible to ignore. My subsequent findings from the lab tests show that the popular literature is only partially true. Read on to find out why.   Read more

Away from Corner Cases: High Density, Low Throughput Wi-Fi

Out of the corner

In my blog called Corner Cases, I mentioned that high density, high throughput (HDHT) cases are in the extreme minority (<1%). In this blog, I would like to discuss High Density, Low Throughput (HDLT), which I believe will be the situation that over half of the installed Wi-Fi infrastructures of the world will face at some point over the next 5-7 years. I want to clarify that that when I use the term “high density”, I’m referring to client density (lots of clients in a physical area), not AP density (lots of APs in a physical area).

Unless you’ve been camping out under a rock, you may have heard the term “Internet of Things” or IoT for short. This moniker refers to the movement toward connecting previously-unconnected devices onto the Internet. To clarify, things are being connected to the Internet, thus we get Internet of Things. So how many of these things are we talking about? Oh… a few I suppose. Gartner is saying there will be 26 billion IoT devices and an additional 7.3 billion smartphones/tablets/PCs by 2020.   Read more

Corner Cases

Trade shows

Most Wi-Fi manufacturer’s marketing departments would have you believe that 99% of all deployments are what I’d call “corner cases.” I call B.S. (as usual). Here are the high-density/high-throughput (HDHT) corner cases that so many manufacturers would have you believe are so prevalent: Large K-12 and University libraries, cafeterias, lecture halls, and auditoriums Stadium or… Read More

802.11ac (Wave-1): MORE Network Engineering Insights

256-QAM is a step function change in data rate

In my previous blog on the 11ac series, I explored 80 MHz channel operation in 802.11ac in the context of data rate, OBSS (Overlapping BSS), network throughput, and auto-channel assignment. 802.11ac (Wave-1): Network Engineering Insights In the present post, I explore the other speed factor of 1.33X that shows up in the Wave-1 data rate equation: (2.16… Read More

How to implement BYOD with Wi-Fi / WIPS assist

Monitor new devices entering Wi-Fi

| Wi-Fi has become the de facto access medium for smart mobile devices in enterprise networks. Sitting at the edge of the network, Wi-Fi can assist greatly in implementing secure and disciplined BYOD in these networks. There is no one-size-fits-all when it comes to BYOD management in the enterprise. However, from my experiences working with Wi-Fi and… Read More
