Wi-Fi 6 CIO Briefing

As a CIO you’ll need to decide not only the technology direction your organisation will take, but more importantly when you will decide to deploy. Wi-Fi is a fundamental networking technology for any business. If you haven't yet upgraded to Wi-Fi 6, here's our CIOs guide for when you should do this.

Wi-Fi Design and the Cinema Story

Wi-Fi works with radio waves. These are similar in nature to sound you can hear (not exactly, but let me have a little artistic licence). Why do you need to have Wi-Fi that works within reasonable RF power bounds? I've come up with a little story to help. Let's translate Wi-Fi in to audio. So here's the story..

Wi-Fi and The Problem With RADAR (DFS)

It sounds like a bit of a stretch for most people that Wi-Fi would have an issue with Radar. Microwave ovens are a pretty well known interferer with Wi-Fi in the 2.4GHz spectrum (they generate alerts for interferers, so we know they're there!)

Reduce Wi-Fi Congestion with DFS

Wi-Fi can be crippled by too many devices competing for airtime, creating a slower experience for all users. One way to reduce the number of devices competing for airtime is to increase the number of channels in use. How do the Dynamic Frequency Selection (DFS) Channels fit into this picture?

WI-Fi 6 vs 5G: Complementary Technologies

One of the common questions I get surrounds the use of Wi-Fi 6 and 5G. Both Wi-Fi 6 and 5G now promise users much higher download speeds and a much more interactive user experience thanks to this.  Why then don’t we all just abandon Wi-Fi 6 and use 5G – especially in the corporate environment, where there are internal costs for deploying a wireless[…]

What is EIRP: EIRP vs Transmit Power

What power is your AP Transmitting at?  With Cisco APs, we can see a power level, which is normally in the range of 1 - 8 (1-6 for some APs), but what is the actual dB power level the AP is transmitting at? This is a combination of a lot of factors - let's take a look.

Wi-Fi Assurance Review

At IPTel, we have developed a lot of techniques over the years to best fault find wireless issues. All too common is an installation which doesn't perform, causes dropouts, is slow and leaves the end customer with an unhappy result. We have the answer - it's called a Wi-Fi Assurance Review and is a service we have developed in house at IPTel.

Cisco SDA Fabric Key Concepts

Software Defined Architecture is the concept that we can configure the network from a centralised management system. In the case of Cisco, this is DNA Center.   SDA removes us as engineers from the CLI configuration layer, although the physical layer still needs careful design in order to ensure no single points of failure and that the physical design[…]

Wi-Fi Troubleshooting: How to Review a Wi-Fi Installation - Part 1

We are getting more and more requests to review Wi-Fi networks which aren't quite meeting the specification. Many customers are finding that companies which don't truly understand Wi-Fi - or how to make it work - have deployed their network and are either incapable of making it work or don't care.

Wi-Fi Troubleshooting: How to Gather Evidence for a Wi-Fi Review: Part 2

Wi-Fi reviews are not the easiest of things. Unlike fault finding most networking, Wi-Fi has the added complexity of RF - and all those multitude of clients. In this blog, we'll take a measured run through on where to start in your fault finding journey.
