LTE Discovery is a powerful signal discovery and analysis tool that allows users to observe a wide range of useful network and signal information while aiding you in staying connected to the best connection possible.

Use this app to identify and record technical LTE information such as GCI, PCI, TAC, Market/Cell ID's. For supported networks, the LTE Band will also be included (Verizon, Sprint, AT&T, T-Mobile, China Telecom).

If you are in an area where LTE is actively being deployed or that has significant gaps in coverage, the app automates the process of cycling your mobile connection to help you connect to the best signal possible. When left running, this app will help you discover LTE in your market without ever looking at your phone! Your phone will find and reconnect to LTE faster, generate a log of the signal, and (optionally) alert you when a signal is found.

As it works in the background it can log each site and connection it finds. This information is then summarized to help you determine how many towers you have connected to. Logs include time, location, PCI, TAC, GCI, and Band. Sprint users have access to the Visual 1x Logger which displays tower, sector, 1900/800mhz signal information via towers pins on an embedded Google Map.

Users that can access their phone's EARFCN DL and UL channels can plug them into the EARFCN card to calculate the precise operating frequency and band. If your LTE network is one of the ones supported ones, the application will generate a frequency range for your signal automatically.

Key features:

-Identifies bands for Verizon, AT&T, Sprint, and T-Mobile
-Advanced signal stats
-Automated visual logger (Sprint + Pro only)
-LTE log queries with unique band and site information (Pro)
-Live band identifier and stats in the notification bar
-EARFCN band calculator (shows range and precise UL and DL frequencies) (Pro)
-Automated search algorithms for LTE
-Data connection reset without requiring root
-Alert notification for connections to bands: 25, 26, and 41
-Attractive and intuitive card-style User Interface
-Wide range of settings to customize your experience (Pro)
-Beautiful Android "Holo" theme design (don't be content with non-Android designs on an Android device)

The free version is full-featured and useful for many cases. However, please consider supporting us by purchasing the in-app pro upgrade for a mere $1.99. This is less than a cup of coffee at Starbucks and helps us keep the lights on.

Please note we do not natively support band identification for every carrier however, users can help us interpret the network information in their area to add band support for their carrier. If you are interested please send us an email.

[NOTE]: This app was originally developed for Sprint users searching for LTE signals in emerging Sprint markets. Though, users with other carriers including both GSM and CDMA carriers can also greatly benefit from using this app. The only features not available for non-Sprint users is tower location and 800Mhz SMR detection. There are no other limitations for other carriers.

From user reports, Verizon sometimes provides tower location, but they are typically inaccurate.

By resetting network connection, you can fix many common network related issues like: continuous low signal, data disconnection, poor call quality, signal instability, and more. You could also fix these issues by restart/reboot your phone, or you could just let LTE Discovery reset your radios in a few seconds.

RATINGS: If you like this app, then please support us rating it 5 stars and giving the app a +1, or let us know how we can improve the app.

SUPPORT: If you notice any problems with the app, please send use the "Send debug email" option in-app and provide us as much information as possible about the problem (including each of the steps to recreate the bug, what happened, and what should have happened).

    Not sure how it does it, but it always works for my LG G2. Especially useful when I'm in an area that I know has LTE available yet my phone stays on 3g. Run this app, and BOOM! LTE service!
