LAS VEGAS -- Tapping into high-speed 4G networks is a real treat, but sometimes a signal is hard to find. Mosaik's new CellMaps Mobile Coverage app for Android is here to help.

Announced today at CTIA 2013, the application lets U.S. Android phone owners see 4G footprints for AT&T, Sprint, T-Mobile, and Verizon in real time. Users can also drill down to see cellular network services in their neck of the woods or scan the overall 4G picture nationally.

Even more exciting is the application's ability to filter 4G coverage in granular details such as 2G, 3G, 4G, and that special golden unicorn of 4G LTE. The app lets you mix and match these filters, too, to get a more tailored view.

Of course a number of applications already offer similar features, such as OpenSignal's eponymous app and CellPhoneCoverageMap by RootMetrics. Both of these compile locational data using the power of crowdsourcing fueled by user reporting.

The CellMaps Mobile Coverage application is available now for a free download via the Google Play store; an iOS version is expected to happen within the "coming months," according to Mosaik. More-detailed information can be gleaned by upgrading the app and purchasing a $1.99 annual subscription.
