If Wi-Fi Networks Can Operate Without Controllers, Why Do Companies Still Use Them?

Last week, we started the discussion about if the architecture of WLAN networks was a relevant topic in 2018. If a company offers both controller and cloud-managed controller-less architectures, ask why do they offer both? If the controller-based design is considered the right path for larger or more complex deployments, what elements, specifically, would contribute to the […]

Why Is OFDMA One Of The Most Important Features In 802.11ax?

Last week, I wrote about Target Wake Time (TWT), and how it was a key feature for IoT and mobile devices in 802.11ax. As exciting as that feature is, OFDMA is arguably the most important new feature correlated to 802.11ax. As a refresher, OFDMA stands for orthogonal frequency division multiple access. OFDMA is a multi-user version of […]

Does Wi-Fi Architecture Matter In 2018?

Last week, I looked at how to avoid RF interference in WLAN deployments. While this is something that affects everyone that uses Wi-Fi, the architecture your network uses is something that you can control (based on which vendor you choose). One of the primary differences between WLAN architectures is where and how the system is controlled. […]

How Will Target Wake Time Help Mobile Devices And IoT In 802.11ax?

As mentioned in a previous post, 802.11ax adds some exciting power saving enhancements and improved resource scheduling features including scheduled sleep and wake times, which is borrowed from 802.11ah. Let’s dive a little deeper. Target Wake Time (TWT) allows devices to negotiate when and how often they will wake up to send or receive data. […]

How Can You Avoid RF Interference In Wi-Fi Deployments?

Last week, I talked about how to deploy a Wi-Fi network that actually works. I mentioned that the key is to avoid RF interference. This week, I want to discuss how to avoid it. First, I want to give you a “cheat sheet” on some basics of Wi-Fi. Wi-Fi Quick Reference Guide: Wi-Fi is a […]

What Is BSS Coloring In 802.11ax?

Last week, we looked at the new features that 802.11ax brings to the 802.11 standard. Let’s take a closer look at BSS Coloring this week. BSS Coloring was a mechanism originally introduced in 802.11ah to assign a different “color” per BSS. Why? To increase capacity in dense environments, we need to increase frequency reuse between […]

Understanding RF Interference In Wi-Fi Deployments

In my last post, I looked at how to pick the best access point. This week, we will be looking at what it takes to deploy a network that actually works. A good Wi-Fi deployment looks like something out of science fiction; you simply put the access points up on the ceiling, and suddenly you […]

What Does 802.11ax Change About The WLAN Standard?

Last time, we looked at the goals of the 802.11ax standard. Let’s break down some of the important changes 11ax introduces (in no particular order). First introduced in 802.11ac, MU-MIMO technology theoretically allows the simultaneous transmitting of multiple frames to different receivers at the same time on the same channel using multiple RF streams to provide […]

What Are The Goals of The 802.11ax Standard?

Last time, we looked how at 802.11ax is going to address common Wi-Fi problems. Before getting more into HOW it’s going to do all these things we need to go back to the basics for a minute. As a reminder, RF is a half-duplex medium, which means that only one radio can transmit on a […]

How Does 802.11ax Address Common Problems With Wi-Fi?

802.11n and 802.11ac introduced some great new technology including PHY and MAC layer enhancements that helped achieve higher data rates. In essence, we built bigger highways and faster cars.
