In the world of wireless design, an engineer must strike a delicate balance between coverage and performance. A high-speed wireless network doesn’t happen by accident. It’s the outcome of careful design and consideration where the art and science of Radio Frequency (RF) mathematics come into …
As a Project-based Network Engineer, I’ve had the ‘pleasure’ of encountering a considerable number of bugs while deploying network infrastructure over the years. Sometimes, these ‘bugs’ have enough impact to grind operations to a halt. With a bit of luck, the challenges will arise early …
Many factors contribute to the successful transmission and reception of a wireless signal. This post will focus on the most common Wi-Fi communications components and each device’s role in transferring data in wireless systems. Wi-Fi Component Overview The image below illustrates the key components discussed …
In this post, I will show you how to cluster Aruba Mobility Controllers to get the benefits of the full range of HA and redundancy features provided by Aruba’s Campus Mobility Architecture. This post assumes you have already deployed a pair of Mobility Conductors. It …
In this post, I will show you how to deploy virtual Aruba AOS8 Mobility Controller in VMware ESXi and add it to a Mobility Conductor cluster. I used AOS version 8.6.0.15, but the steps should be the same for other 8.x versions. Check out this …
What is a Radio Frequency? Radio frequency (RF) is a form of electromagnetic energy typically used in wireless communications systems. RF signals are generated by a transmitting device as an alternating current (AC) which produces electromagnetic waves as it radiates away from the device’s antenna. …
In this post, I will show you how to configure Aruba AOS8 Mobility Conductor Redundancy. While you can operate your Aruba Wireless network using a single Mobility Conductor, the platform license covers you for two appliances. So unless you are low on resources in your …
In this post, I will show you how to deploy a pair of Aruba AOS8 Mobility Conductors in VMware ESXi with a basic setup so you can start adding Mobility Controllers. I used AOS version 8.6.0.15, but the steps should be the same for other …
You’ve just purchased some shiny new Wireless Access Points from Vendor X. Vendor X has promised you lightning-fast, wired-like connection speeds. Product datasheets speak of incomprehensible Wi-Fi data rates and sky-high maximum client connection limits; it all sounds great! You deploy the APs which are …
This article outlines the complete list of 802.11 standards and amendments and is updated as developments are made. As each 802.11 standard is updated by the IEEE, the previous iterations and any amendments that exist at the time are revised and incorporated into a single …
