Mobile networks have become the backbone of telecommunications, with the widespread adoption of smartphones, tablets, and other mobile devices.
Frequencies
Mobile networks are also known as cellular networks. They're made up of "cells," which are areas of land that are typically hexagonal, have at least one transceiver cell tower within their area, and use various radio frequencies. These cells connect to one another and to telephone switches or exchanges. Cell towers connect to each other to hand off packets of signals — data, voice, and text messaging — ultimately bringing these signals to mobile devices such as phones and tablets that act as receivers.
Providers use each others' towers in many areas, creating a complex web that offers the widest possible network coverage to subscribers.

Frequencies
Many network subscribers can use mobile networks' frequencies at the same time. Cell tower sites and mobile devices manipulate the frequencies so that they can use low-power transmitters to supply their services with the least possible interference.
Generation of Networks
Mobile networks have changing through a series of generations, each representing significant technological improvements over the previous generations. The first two generations of mobile networks first introduced analog voice (1G) and then digital voice (2G). Subsequent generations supported the proliferation of smartphones by introducing data connections (3G) and allowing access to the internet. 4G service networks improved data connections, making them faster and better able to provide greater bandwidth for uses such as streaming.
The latest technology is the 5G network, which promises even faster speeds and greater bandwidth compared with 4G while reducing interference with other nearby wireless devices. Where 4G uses frequencies below 6 GHz, newer 5G networks use shorter wavelength signals with much higher frequencies, in the range of 30 GHz to 300 GHz. These frequencies provide higher bandwidth and allow signals to be more directional, thus reducing interference.
The promise of very high 5G wireless speeds opens the possibility of replacing traditional wired connections to your home, such as cable, with a wireless one, thus greatly expanding the availability of high-speed internet access.
