1G or (1-G) refers to the first generation of wireless telephone technology (mobile telecommunications). These are the analog telecommunication standards that were introduced in 1979 and the early to mid-1980s and continued until being replaced by 2G digital telecommunications.

The main difference between the two mobile telephone systems (1G and 2G), is that the radio signals used by 1G network are analog, while 2G networks are digital.

2G (or 2-G) provides three primary benefits over their predecessors: phone conversations are digitally encrypted; 2G systems are significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels;
and 2G introduced data services for mobile, starting with SMS (Short Message Service) plain text-based messages.
2G technologies enable the various mobile phone networks to provide the services such as text messages, picture messages and MMS (Multimedia Message Service).
It has 3 main services: Bearer services is one of them which is also known as data services and communication.

Encryption
In cryptography, encryption is the process of encoding information.
This process converts the original representation of the information, known as plaintext

Disk encryption
Disk encryption is a technology which protects information by converting it into unreadable code that cannot be deciphered easily by unauthorized people

A simple encoder or simply an encoder in digital electronics is a one-hot to binary converter.
That is, if there are 2n input lines, and at most only one of them will ever be high, the binary code of this 'hot' line is produced on the n-bit output lines

Some 5G pundits contend that the new network generates radiofrequency radiation that can damage DNA and lead to cancer;
cause oxidative damage that can cause premature aging;
disrupt cell metabolism;
and potentially lead to other diseases through the generation of stress proteins.Dec 18, 2019
