difference between 1g 2g 3g 4g technology

Since introducing the first commercial mobile phone by Motorola in 1983, mobile technology has come a long way. This technology, protocol, offering services or speed, changes in mobile telephony has been recorded as a generation of mobile communication. Here we will discuss the basic characteristics of these generations, which separate it from previous generations.

 1G Technology

1G refers to the first generation of wireless mobile communications where analog signals were used to transmit data. It was introduced in America in the early 1980s and it was specially designed for voice communication.

Some features of 1G communication are -

Up to 2.4 kbps speed

Sound quality

Large phones with limited battery

No data security

2G Technology

2G refers to the second generation of mobile telephony that used digital signal for the first time. It was launched in Finland in 1991 and used GSM technology in it. 2G network came in the form of CMS Global Roaming System, which enabled connectivity across the world. 2G technology has adequate protection for both the sensor and the receiver. It allows digital encryption data to be transmitted in such a way that only the desired receiver can receive and read it.

Some of the key features of 2G communication are:

It has data speed up to 64 kbps

It is possible to send text and multimedia messages in

Better quality than 1G

When GPRS technology was introduced, it enabled web browsing, e-mail services and faster upload / download speed. 2G with GPRS is also called 2.5G, which is a small step in the next mobile generation.

 3G Technology

The first pre-commercial 3G network was launched in 1998 by NTT DoCoMo in Japan, the third generation of mobile telephony (3G) started with the beginning of the new millennium and offered great advancement over the previous generations. 3G technology connects multimedia features to 2G phones by allowing video, audio and graphics applications to broadcast over the network. On 3G phones, you can stream video or make video calls. 3G is also known as IMT-2000.

There are some features of this generation -

Data speed of up to 2 Mbps from 144 kbps

High speed web browsing

Playing web based applications such as video conferencing, multimedia e-mail etc.

Easy and Fast transfer of audio and video files

3D Gaming

Every coin has two sides. Here are some downsides of 3G technology -

Expensive mobile phones

Higher infrastructure costs such as license fees and mobile towers

Trained personnel required for installed infrastructure

Intermediate Generation, 3.5G simultaneously disseminated mobile telephony and data technologies and paved the way for next-generation mobile communications.

4G Technology

Fourth generation (4G) mobile communications were launched in 2011, while maintaining the trend of a new mobile generation every decade. It provides ultra-broadband internet access for mobile devices. High data transfer rates, and even make the 4G network suitable for use in USB wireless modems for internet access.

Its major features are:

Speed ​​of 1 MBPS to 100 MBPS

Use of mobile web

High Definition Mobile TV

Cloud Computing

IP telephony
