It covers mobile technologies, such as 3G and 4G, and even includes a bit of information on smartphone operating systems and the companies that make the cell phones and other mobile technology devices we all use.

What is "Antenna"?

An antenna is a physical component placed in a device to send and receive radio waves and is the chief piece of hardware for gaining a cellular signal.
