Warehouses have very special requirements when it comes to providing Wi-Fi coverage, for a whole host of reasons. They are a challenging environment in RF terms - there's often high ceilings, lots and lots of metal racking, RF attenuation is constantly changing (shelves filling and emptying, forklifts moving loads around and so on) and small devices[…]

Elastic Wi-Fi. It’s probably not a term you’ve heard before in relation to wireless and WiFi. I’m going to run through some principles I’ve learnt over a few years in the business to help you improve Wi-Fi performance, but first, I’ll digress...

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. 

There’s multiple challenges in designing, deploying and maintaining a network environment. We can’t go through all these in one blog  - there’s just too many, but in this blog, we’re going to have a quick run though on those that SDN (Software Defined Networking) can help solve.

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.

In this blog, we'll take a quick look at the functions, features and power level comparisons for Cisco Access Points. I thought it would be useful to have these in one place for easy comparison.

I've touched on the subject of power caps. The issue is a reasonably simple one about not having an AP blasting at maximum power, while you have a low powered device broadcasting back.  In explaining the principle of exactly why this doesn't work, I've come up with a little story to help. Let's translate Wi-Fi in to audio. So here's the scenario.

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!)

During fault finding with WLAN networks, there comes a point where you just have to take it down to the lowest level. Sometimes it is because you have a bug and you need to see the exact behaviour of devices in the network, in order to work out where the issue lies.
