Ekahau has GPS assisted survey http://www.ekahau.com/products/ekahau-site-survey/overview.html
I've used it to map our outdoor Wifi deployment. You need a GPS, and you need to be a bit careful on how you collect your results. Driving 30MPH inside a car did not necessarily equate to walking around with a laptop. (Signal loss from being inside a car, as well as the impact on roaming while moving that fast) Mike On Tue, Nov 13, 2012 at 7:28 AM, Osborne, Bruce W <[email protected]>wrote: > Philippe,**** > > ** ** > > So, in the US, power line AC is 60Hz and 802.11AC is 5Hz.
