How exciting, a free app for Android users that want to know their LTE connection's status, monitor signal strength with logging, and get more specific details regarding their cellular connection. The app is called LTE Discovery and it’s currently available from the Google Play Store.
This app can identify LTE bands for the major American carriers – AT&T, T-Mobile, Verizon, Sprint and with networks from some other countries. It also posts a live band identifier with signal data in the notification bar so you can do a quick check by pulling down the drawer. If your signal is being sluggish for some reason, you can tap a button to reset the cell radio and re-connect to the strongest signal source available. If the signal falls below a certain threshold, you can have it reset automatically. It will issue alerts when specific LTE bands and GCIs connect and disconnect. If you want to trace the cellular activity it can be logged.
LTE Discovery also supports advanced LTE, 4G, 3G, GSM, and CDMA networks, showing data about GCI, PCI, TAC, RSRP, RSRQ, band, EARFCN, and frequency parameters. Not all devices and carriers are supported for advanced signal data, but for those that do work with the app, LTE Discovery gives the kind of output that turns it into a very advanced tool designed for power users. Even for the more basic user, the app provides an easy way to determine the LTE band your cellular device is using. In cases where your location has multiple cell towers, it's possible not all towers are broadcasting the same bands. Certain routers, such as the Pepwave Max products, let the user force their cellular connection to a specific band, which in turn may provide a more stable, or even faster, connection.
