Understanding which wireless network is actually the best

RootMetrics and OpenSignal are two good examples of the most common approach to actually measuring network signal and speed (as opposed to something like Nielsen, which surveys users for their perception of their network). RootMetrics buys devices and sends testers out to set locations, where they test all the networks head-to-head and record the results. […] OpenSignal takes a completely different approach. Rather than sending employees out with test devices, it encourages users to download an app. Users then conduct speed tests and coverage tests as they go about their day-to-day lives, and the data is uploaded to OpenSignal. – Chris Mills, BGR http://ift.tt/2lVu1E2
