1G Network

In this tutorial, we are going to see What is the 1G (First Generation) Mobile Network?

The first generation of mobile communications (known as 1G) was analog and was made up of relatively large devices. It was based on the following standards:

• AMPS (Advanced Mobile Phone System), which appeared in 1976 in the United States, was the first cellular network standard. Used mainly in the United States, Russia and Asia, this first-generation analog network had weak security mechanisms that made it possible to hack into telephone lines.
• TACS (Total Access Communication System) is the European version of the AMPS model. Using the 900 MHz frequency band, this system was widely used in England, then in Asia (Hong-Kong and Japan).
• ETACS (Extended Total Access Communication System) is an improved version of the TACS standard developed in the United Kingdom using a larger number of communication channels.

 
The first generation cellular networks have been made obsolete with the emergence of the second generation which is entirely digital.
