Capacitors – 2pF, 3.3pF, 4.7pF, 47pF, 0.1µF, 4.7µF, 47µF, 1µF,

30pF Trimmer Capacitor

LED

L1 - Coils 3 Turn 24 AWG,

L2 - 4 Turn 24 AWG

Antenna 15 Turn 24 AWG

BF495 Transistor

ON/OFF Switch

9V Battery

In this video it shows how to detect the mobile network which your Android phone is using.

It uses getDataNetworkType method of the TelephonyManager class to get the network type being currently available on the Android Phone.

Below is the list of the return values from the getDataNetworkType method. In our code using switch case, we have classified them for 2G, 3G, 4G and 5G network types.

This method needs the permission to READ_PHONE_STATE from the user, so respective permission checks are added in the java code and Manifest file of the project.
