Wi-Fi Riddles: ‘Too good’ signal is bad signal?

TooMuchPowerWhile I was working on the next part of the “Unobvious and overlooked Wi-Fi” (which is about channels), I got an interesting knowledge nugget from our engineering. We all know that there is a lower limit to receiver sensitivity, we all know that there must be some upper limit, after which the Rx signal is so powerful, it simply oversaturates the radio. But that is it? Now I know it, even though I did not ask for it explicitly – I merely happened to run into a situation where it matters.. Read on…


Running a WLAN controller in VMWare Player

Motorola WiNG5.6 firmware images were finally posted last week, and along them, the VX9000 cloud controller DEMO image. I am very excited about it, as it allows me to run a VM version of Motorola’s top controller (or cluster, or hierarchy for that sake) right on my laptop!
