What is 3g: the understanding of the network in the scale of humanity

For a long time everybody forgot about 2G, now the standard of access is the 3g network. What is it? A small device? Partly yes, but the essence of the system of access to mobile communications and the Internet is much more complicated.

Device

Just five years ago, the 3G device was much larger than the current "prototypes" and it looked like a cell phone. It provides high-speed access not only to the Internet, but also to radio waves, to mobile communications. It allows you to use the connection mobilely, and not permanently, as it was before. The wires were far in the past.

Signal

The answer to the question, what is 3g, is not limited to the consideration and description of this device. To maintain such a high-speed connection, it is also necessary to use such a powerful data transmission over the network - data transmission over broadband networks allowed such an effect to be achieved.

Features

The prerogative of using the 3G network was multimedia services, including in the global network. Hence the popular mention of 3G as a link between the third generation. It allows you not just to communicate, but to communicate in a new form - video. We now hear our interlocutor and see him. And if we all already know how this works on the Internet, how does this manifest in mobile communication? With the help of a videophone! .. This is really a breakthrough in mobile communication technologies! And now with the new models of cell phones everyone can go online, watch movies, TV shows.

Another feature that reveals the answer to the question, what is 3g, is the possibility of staying in a constant on-line mode. At the same time, the form of payment, units of measurement, has also changed. If you previously paid for the time spent on the network, in the 3g format, the amount of information received (and transmitted) is also paid.

Among other features of the new communication format: international roaming, support for several operators, communication with the satellite, the speed of up to 2 Mbps.

All this becomes possible due to the continuous transmission of data in the decimeter range. Nothing more powerful and more global has not been invented yet.

Quality standard

What is 3g as a term? This concept says not only about high speeds, but also used to describe the high quality of the provided communication: sound, video, multimedia. To achieve this result, manufacturers were forced to follow international standards and technical requirements (UTI). Recommendations are reduced to the features of using the frequency spectrum of the generation 3g: achieving increased efficiency, capacity and speed from 144 kbps (when driving, for example, in a car, the speed of which can reach 120 km per hour) to 2 Mbps (with immobility).

What does 3g mean to the user, in addition to high-speed Internet access? The third generation will be appreciated by corporate customers, using conference calls and remote access to their database (wirelessly and from anywhere). Equally, a unique service has been appreciated by many: it is an opportunity to pay for services through a telephone (the so-called mobile bank), thanks to which there is no need to look for a terminal or a bank branch.

The spread of 3 G

About what is 3g, the Russians learned not so long ago. The introduction of the latest technologies in mobile communication (in all senses of this term) took a lot of time - 10 years. Initially, the 3G network was widely used in Japan, then in the countries of Asia, in the US and, finally, "came" to the operators of Europe.

The 3G network is the most complicated data transmission system, including a "receiver" of signals: radio waves, cellular operators, the global Internet. On 3G have high hopes: developing it, it will be possible to create a global mobile network, to unite all operators. But if the network will exist under different protocols (today there are 2 of them), then the ultimate, "iridescent" goal will not be achieved ...
