SD-WAN: Application & Identity-Driven Policies

Software-Defined Wide Area Networking (SD-WAN) is an innovative new approach to the deployment, management and operation of WANs. In this 5-part series, the key benefits of this exciting new technology will be explored. WAN connectivity is often a costly investment, whether it’s MPLS, broadband or cellular. Any package purchased through a service provider will be […]

Aerohive Atom AP30: Retail Analytics Kit In A Box

Retail has become a favorite location to provide guest wireless access. Whether finding out where an item is located in the store, checking online pricing, or looking up coupons, retail Wi-Fi is here to stay. Many retail locations such as shopping malls provide building-wide Wi-Fi for guest access, so the individual stores don’t have to […]

Aerohive Atom AP30: Enterprise Coverage At A Great Price

When the Wi-Fi first came to the enterprise, it had two things that were commonplace: it was expensive, and it was complicated. The tricky thing for the Wi-Fi industry is as the technology for WLAN’s got better, our devices continued to push the boundaries of the network. If the access points could provide faster access, […]

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 […]

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. […]

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 […]

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.

Aerohive Atom AP30: My New Favorite Access Point

I came into the IT world when 802.11n was the primary Wi-Fi technology being used. Even back then, I always thought that wireless technology was racing towards a single common purpose: making deployments and management simpler. One of the challenges that I’ve had (and I know others have as well) is dealing with legacy cabling […]
