At IPTel we've been working on the deployed of Cisco SD Access. This is pretty new technology for most people and so has a bit of mystery to how this is deployed. In this blog, we'll take a look at how a real world deployment of Cisco SD Access looks.
Friend and colleague, George Stefanick is will known in Wi-Fi circles. George has provided us with a pretty concise list of a lot of the gotchas in Wi-Fi design - have a read of the full blog for an interesting walk through George's Top 30 Technical Wi-Fi thoughts.
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.
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[…]
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 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..
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!)
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?
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.
