1g 2g 3g 4g 5g telecom technologies

The family of cellular mobile telecommunications technologies, developed to support worldwide portable wireless communications. The first generation (1G) systems were introduced by Nippon Telegraph and Telephone (NTT) in 1979. 1G technology defined mobiles as “mobile stations” (MS), and/or base stations (BS), with analog transmission/reception and voice as the only service coverage

To help you understand the different generations of cellular and mobile networks, we’ll cover the following topics: 1G – 2G – 3G – 4G – 5G – 6G.

1G was the original digital wireless mobile technology, introduced in 1991. The term “1G” is often used to describe this generation as a whole, rather than specific standards. 2G – Although 2G is technically the second-generation of wireless network technologies, it includes several important standards such as GSM and CDMA. The main advantage over the first generation (1G) was improved data speed and call quality. 3G – 3G refers to any mobile phone standard that offers data communication speeds comparable to traditional home broadband services. 4G stands for Fourth Generation (4G) wireless protocol Mobile Broadband Internet access

The history of mobile communications has evolved from analog to more sophisticated digital systems. The digital shift brought about a fifth generation (5G) standardization process.

A mobile phone is a handheld transceiver meant to be carried by an individual and communicate with fixed stations (base stations) in the mobile telephony network. Mobile phones are also known as cell phones, hand-held phones, and mobiles. Mobile phones are used primarily for voice communications, but may also provide other services such as text messaging, short range wireless Internet access, gaming applications and multimedia playback.


1G is the initial generation of wireless cellular technology and introduced voice services, 2G introduced text messaging and Picture Messages (MMS), 3G introduced high speed data transmission. 4G introduce Long Term Evolution (LTE), 5G introduces higher frequencies than those used in 4G networks

The history of cellular mobile telecommunications technologies describes the major commercial developments that made mobile phones widely available. The first-generation analog cellular system was introduced in 1979 and became widely available in the 1980s. This generation was followed by the digital cellular system, which was introduced in 1981 and remains predominant worldwide today

Cellular mobile generations can be described in two ways: The first way is by the first digit of the global system for mobile (GSM) network code; The second method is by the radio spectrum band used by the network.

Mobile communications began with the development of several national analog cellular standards in the 1980s. These were followed by digital cellular systems in the 1990s, and more recent 3G and 4G multiple-generation standards. The technology keeps developing.


2G cellular mobile telecom generation is the second-generation (2G) of mobile phone mobile communications technology, generally indicating that it is the second standard to emerge (and thus succeeding 1G). The system provides additional new features such as short message service (SMS), enhanced call setting, improved security and roaming capabilities.

2G celluar mobile telecommunication generation is technology by which the mobile communication is carried by digital waves.

This generation of cellular mobile telecommunications technology is characterized by an initial deployment of what are now called 2G networks or 2G wireless (aka GSM, TDMA and CDMA), with 2G meaning the second generation of wireless communications.

2G is a cellular mobile telecommunications technology continued as the predominant standard until 2012.

2G is the second generation of cellular mobile telecommunication standard that became operational in October 1998 and replaced the 1G analog cellular system. 2G provided greater capacity and better quality, with data transmission rates of up to 9.6 kbit/s (and later 21.1 kbit/s) and a second-generation text service (“T9”).

The 2nd generation mobile cellular telecommunications technology, is the world’s first duplex communication, voice and digital services are packaged into a digital signal. In 1997, the global full coverage has been launched, it marks the beginning of the digital age of telecommunications industry. Because it is the first generation of digital cellular telecommunications for commercial use in the world, so people call it “2G”, that is two generations.


3g cellular mobile telecom generation is a new generation of cellular mobile telecommunication technologies that provide wide-area wireless Internet access, typically download speeds of 200–500 kbit/s and upload speeds of 50–110 kbit/s

3g cellular generation is a mobile telecom generation that uses the 3g standard. 3g cellular mobile telecom generations allows faster data transfer rates, improved voice quality and better access to web content using third generation wireless technologies, including UMTS and HSDPA

The 3G mobile telecom generation is the third generation in mobile telecommunications standards.

3G is a fast, reliable broadband technology capable of delivering a wide range of fixed, wireless and mobile services including voice, data and video.

This generation of mobile networks uses third-generation wireless communication standards, such as 3GPP and UMTS. 2g networks began to offer data services with the advent of Enhanced Data rates for GSM Evolution (EDGE), which was introduced in 2003 along with WCDMA (Wideband Code Division Multiple Access). EDGE made possible higher speed data transfer rates while retaining 2G network coverage.

Cell phones are portable telephones that above all, allow you to contact people wherever you go. The 3rd generation of mobile phones is 3G or third-generation. They offer multimedia services such as internet access and video calls.

4G LTE architecture


4g cellular mobile telecom generation, a 4g wireless technology, is a more efficient use of the radio spectrum.

4g cellular mobile telecom generation is the next generation in wireless communication systems. It allows data to be transmitted between mobile devices, cell sites and the Internet at four times the rate of 3g, so it is also called fourth-generation wireless technology.

The 4g cellular mobile telecom generation is the third major mobile telecommunications technology.

4G cellular mobile telecommunications follows 2G and 3G. 4G is a short form for fourth generation, defining it as the following: “It delivers download speeds of up to 150 megabits per second, more than twice as fast as 3G.” The 3rd Generation Partnership Project (3GPP) has standardized these technologies under specifications and granted them an official name: Long Term Evolution (LTE).

4g or fourth generation is the most recent set of standards for wireless mobile telecommunications. It provides broadband Internet access, superfast download speeds and multimedia applications such as streaming video services.

4G is a standard for high-speed mobile broadband based on the evolution of the GSM standard. A 4G system provides mobile ultra-broadband Internet access, thus enabling similar services as fixed broadband.

Network architecture evolution from 4g to 5g


5G Architecture

5g cellular mobile telecom generation will create a new shared socio-economic ecosystem. It has the potential to revolutionize almost everything: the way people work and live, the way we shop, the way we travel and communicate, the ways we entertain ourselves.

5g cellular mobile telecom generation is the fifth generation of mobile telecommunication technology, a set of standards that provide enhanced mobile broadband capabilities and may be used to address a wider array of subscribers’ needs, at lower cost and better coverage.

Cellular mobile telecom generation 5g is a part of the 6th generation of cellular systems.

5G is the name for the next generation of wireless technology. It will enable you to do things on your phone that were impossible before, like downloading a movie in seconds over the cellular network.


The 6g cellular mobile telecom generation is the next generation of wireless communication.

A new era of mobile telecom with the generation of 6G.

6g offers a new way to experience wireless. With 6g, faster connectivity and greater capacity means even better coverage in more places. And it’s the first network designed specifically for connected devices—from smartphones and wearables to autonomous cars that can link with each other and their environment.

A new, next-generation of mobile telecommunications, 6G networking technology will carry more traffic than the combined traffic of 4G and 5G.
