Background Scanning is Dead

Posted by Sean Blanton on Jul 29, 2016

It’s no secret that WiFi is becoming the primary (sometimes only) way to access the network in major enterprises, universities, and schools. WiFi networks are seeing growing numbers of devices, and in turn growing traffic of high-bandwidth voice and video applications. You can no longer simply plug in an access point and expect it to maintain strong, reliable connections: you need access points that can dynamically adjust themselves and the clients around them when conditions turn for the worse. But how can an access point do that? Two words: dedicated scanning.

Three Ways to Get the Most From Your RF Environment

Posted by Robert Ferruolo (Dr. RF) on Jul 26, 2016

Networks are a shared resource and as such suffer from the tragedy of the commons. In networking terms this means that applications and protocols are designed to do their job (self-interest) with no regard to the impact on the network (commons).

Comprehensive Application Control For Your WLAN

Posted by Abhinav Mathur on Jul 23, 2016

Release 8.0 of Mojo Wireless Manager included Application Visibility. With release 8.1 we are increasing application control power by adding Application Firewall. With the two together, you get robust application management. Here’s why you need it.

Mojo Packets: Mythbusting a “Rule” of WiFi Roaming

Posted by Davneetsingh Narang on Jul 20, 2016

Every wireless troubleshooting story starts with a user complaint: “There’s a problem with the WiFi.” (Although sometimes the complaint is in more colorful language.) Here’s how we easily solved one issue using Mojo Packets, our online troubleshooting tool (formerly called WizShark), and busted the myth that stationary clients don’t roam.

Mojo Cloud Managed Platform Release 8.1 — July 2016

Posted by Sean Blanton on Jul 18, 2016

Happy summer, Mojo World! It’s time again for another cloud release and I want to take some time to highlight a couple of key items. Our goal is simple: deliver superior enterprise WiFi. And though our past releases focused on our cloud architecture built around WiFi analytics and automation, this time we want to hone in on the cool new things our access points are doing to help ensure your WiFi is the best it can be. So let’s focus on two specific additions: Mojo Air and the Mojo Cluster Protocol (MCP).

Radio Resource Management That Never Sleeps

Posted by Sriram Venkiteswaran on Jul 16, 2016

RRM (Radio Resource Management) is a collection of techniques in which access point radios continuously analyze the RF spectrum to do the following:

  1. Adjust the operating channel to mitigate co-channel interference.
  2. Adjust the operating power to optimize coverage.
  3. Provide coverage hole protection by automatically increasing the power when neighbor APs fail.
  4. Ensure clients are evenly load-balanced between the APs, between channels, and between bands.
  5. Ensure clients are connected to the best possible access points (address “sticky client” behavior) by steering them to the right access point.
  6. Ensure air time fairness by making sure less-capable clients do not consume excess bandwidth.

Targeting WiFi Dinosaurs

Posted by Rick Wilmer on Jul 14, 2016

Imagine 65 million years ago, a Tyrannosaurus rex looking up at the night sky. (Despite what we saw in Jurassic Park, the T. rex actually had excellent eyesight.) She might enjoy looking at the stars, and maybe one night, she saw a shooting star moving across the sky. She gave it a second glance, and probably should have paid closer attention, but continued to move on into the night.

The Five New Changes to E-Rate Funding You Shouldn’t Ignore

Posted by Erika Hashemi on Jul 12, 2016

Last month, USAC released E-Rate Funding Year 2016 Wave #1, and now roughly $17M in recently-approved funds is at risk of being delayed or cancelled if applicants don’t adhere to these new changes in the E-Rate funding process. We’ve sorted through all of the important updates from USAC to provide you with a simplified list of what’s new, and what’s needed in order to obtain your E-Rate reimbursements.

A Change for the Better: How the Cloud Extends the Power of Your WiFi

Posted by Sean Blanton on Jul 11, 2016

We’ve all been there right? Stuck in a rut, unable to break free from the ways we’ve always done things. No, I’m not talking about your love life (well, not in this post, anyway), I’m talking about WiFi! Big things are happening in the world of enterprise WiFi, and we at Mojo are excited to lead the efforts to innovate our business and deliver services and specialized features that really make a difference. Let’s dive into an example, shall we?

802.11ax: Optimistic CSMA for Efficient Channel Reuse in WiFi

Posted by Hemant Chaskar on Jul 9, 2016

802.11ax is the new 802.11 standard currently in the making. Unlike earlier 802.11 standards that mainly focused on increasing raw link speeds, the design objective now is to increase airtime efficiency. One feature it introduces is OFDMA (Orthogonal Frequency-Division Multiple Access) to address the airtime inefficiency caused by short WiFi frames. The other is dynamic sensitivity control, which modifies traditional CSMA (Carrier Sense Multiple Access) to address airtime inefficiency caused by co-channel interference during channel reuse.
