Crowd-sourcing 4G LTE in the US
These diagrams may look a bit like weather maps but they actually provide a crowd-sourced picture of where 4G mobile networks are up and running across the US, mapping out the summer of LTE.
Mobile performance watcher RootMetrics can use its Android and iOS application to look for 4G LTE signals all over the US and users can use the app to run speed tests on the network to which they are connected.
"These have been generated from crowd-sourced data gathered from users of our CoverageMap app," says Patrick Linder, communications manager at RootMetrics. "The maps reflect any time someone from the crowd accessed an LTE network and we registered an LTE signal strength."
So, while the maps can't show how thorough the LTE coverage is yet, they might reveal 4G connectivity in areas that haven't even been officially announced by carriers yet.
