The story of the evolution of generations of communications 1G 2G 3G 4G

I’ve become smart phones in the recent period in the case of permanent evolution, and spread significantly, which leads to some questions about the technology used in communication, some may wonder what the 3G, for example, and what is the fourth generation 4G? Maalfrq them?

Proceeding from the ground up based on the first generation 1G and even today heralds that the wireless industry is in the path of a large and promising innovations in the future, knowing that we are currently using scale LTE networks now known as 4G.

With the rapid development, there has been a rapid growth at the same pace in the use of these services, and take advantage of the bandwidth that provides the recent worldwide.

As a definition for generations to connect and understand what it means every generation “1G, 2G, 3G, 4G”, and the definition of evolution, we have to know the differences among them.

Beginning should be the definition that the technology used in the majority of countries in the world to connect to the “GSM”, or mobile system global “Global System Mobile”, Technology by phone card SIM, which occurred in this service many developments over the past few years, which made us call Each stage of this evolution of the word “generation”.
The first generation 1G

The first generation of this technology was 1G, appeared in 1981, it was the first technology to connect via mobile devices, this technology not only supports voice calls, since it does not support text messaging or online.
The second generation 2G

The second generation 2G, or the so called “GPRS” short of “General packet radio service” are technology provides voice mail service with the availability of fast internet is somewhat slow, but that this data “Ir online” only suitable for the performance of the functions of e-mail, any non- suitable for browsing websites on the Internet or download video clips, but anyway this was the technology has added a remarkable development in the service then, as it is technology that has added the ability to send text messages. It is worth mentioning that the speed of the Internet connection “maximum” that were provided are between 56-114 kbps. Then after popping technology provides greater speed connection to the Internet 0.400 KB per second, it’s technology 2.75G, or so-called EDGE acronym for “Enhanced Data rates for GSM Evolution”.
The 3G

Preceded the technology EDGE emergence of the third generation, which appeared after the evolution of striking with the upload speed of the Internet of 400-700 kbps, convenient to watch and download video clips, where the cost developed communications companies huge amounts of money because of the need to build a lot of towers contact because it supports waves differ from the waves of the second generation. But worth mentioning that the voice call and SMS is still enabled the second generation, the Internet data it passes through the towers 3G. Then after that technology has evolved 3,5 G, third-generation developer called “Broadband” or broadband technology, allows you to download online speed of up to 7.2 Mbps, which is still in the expansion until this moment.

The evolution of generations Communications

Any conclusion, we can say:

1G was the first generation of voice communications only
The second generation 2G connections + Messages + Internet for e-mail services
A 3G provides connections + Internet at high speed
The fourth generation provides voice communications + Internet at high speed.

2G 3G 4G

Of course, all smart phones are on the network to connect to 2G, and the modern ones are to connect to 4G.

Where it is currently being broadcast 2G, 3G, 4G at the same time by the actuators, there is no preference for the new, the reason for this is to meet the need of different types of phones.

This year, we have seen the use of data in all parts of the world has surpassed the 1 EB, where every 1 ExaByte = 1 مليار GB, and this is a large amount of data.

This massive development is not surprising to any one, because the revolution of smart phones, which are issued continuously fueling this growth is happening, where it is stated that by the year 2017.

Each of looking forward to the development of wireless networks, we are on the right track and soon we will see continued improvements in network performance, and an increase in facilities continuously to bring more smartphones in developing markets.
