3G. This word is pronounced in television and radio advertisements. This acronym is printed on the colorful pages of magazines. This inscription appears on multi-colored billboards along the city's roads more often than the green light at traffic lights.

First things first

Answering the question of what 3G is is not as easy as it seems at first glance. If you read the meaning of the word in the reference book, little will become clear, most likely, additional questions will arise. You need to start explaining the term with a story about what the Internet is in general.

The classic interpretation of the word "Internet" suggests that it is a global data warehouse. Cables, through which packets of information run byte by byte, lie under the waters of the oceans, connecting continents and users. It doesn't matter where the server will be located with the text answering the question "what is 3G?" (in Africa, America or Europe) - it can be accessed from anywhere in the world. Also, this concept should include all systems and technologies that allow you to store data, process and exchange them.

The rapid exchange of information allows thousands of people to work remotely, study, take distance courses, just communicate. The Internet has given a huge impetus to the development of the entire information community.

3G was not built right away

The Internet has developed, though rapidly, but gradually. Previously, connection to the World Wide Web could only be carried out using a cable, which made it possible to use services only in a home or office. If the user wanted to know what 3G is from sources posted on the Internet, he would have to go home or get to the nearest cafe to get information - waste extra time.

To overcome these very inconvenient limitations, it was decided to create new Internet technologies that would not tie the user to a specific place, and even in a compact design (which are modern phones, tablets, laptops).

What is 3G in a smartphone, why is this term only applicable to portable devices?

All mobile devices belong to a generation. At the beginning of the development of communications, 1G phones appeared, often jokingly referred to as "bricks". They could transmit speech, but they were not able to use the Internet even at the slowest speeds.

After them, as you might guess, the second generation (2G) has been developed. The appearance of these devices marked the transition to digital methods of information processing. At the same time, the first attempts were made to teach phones to use the capabilities of the World Wide Web, and, I must say, it worked out. The data transfer speed was slow, but it was enough to send an email or download a small text file.

3G devices appeared at the turn of the 20th and 21st centuries. They made it possible to transmit information at hitherto unattainable speeds. It was this generation of phones that made the mobile Internet convenient, made it possible to use the resources of the World Wide Web outside the home in full.

What is 3G in a smartphone from a consumer's point of view, what functions does this technology provide that are not available in previous generations?

  1. Communicate with friends (or business correspondence) anywhere.
  2. Video call.
  3. Ability to download files.
  4. Modern multimedia features.
  5. Global roaming.

Technical details

Answering the question "what is a 3G connection?" technical language, the following theses can be distinguished:

  1. CDMA2000 IS-95 and WCDMA (UMTC) are 3G standards. The first is used in Europe and Russia, the second - in Asia and the USA. Phones that support only one of the standards cannot work on networks that use the other.
  2. Manuals list a maximum data rate of 2 Mb/s (three times faster than 2G), but today 3G networks are constantly improving to overcome this limitation.
  3. 3G networks work in parallel with GSM. This makes it possible to use two standards at once in one phone. Users of older devices do not have to change them to more expensive ones if this is not necessary. New multi-standard devices have battery-saving features that automatically switch your phone to different networks at different times.
  4. The transition between 2G and 3G modes of operation occurs instantly, without interruption.

The rapid development of Internet technologies in portable devices could not bypass its big brother - a personal computer. After the advent of third-generation wireless networks in mobile phones, the World Wide Web acquired new users who had not previously accessed the Web from a computer, because it still remained tied to the provider's cable. In large cities, this problem cannot be considered serious, but in hard-to-reach areas it is often impossible to lay new lines.

It became clear that such a 3G solution could be a great help for regions far from the centers. It is enough to install several stations to cover the whole area. For users, this creates a fast and inexpensive way to connect to the World Wide Web. But connecting your phone to a computer as a communication device is not the most convenient solution. It is better to use a 3G modem, which is much smaller, does not require extra wires to connect and can work on any computer without installing special programs. In addition, the smartphone will not be busy browsing the web when necessary during a telephone conversation.

Often, providers use higher frequencies for WCDMA operation, and this worsens the quality of communication, although under certain conditions it increases the speed of transmitting and receiving information. In this case, an external antenna can be connected to the modem, which amplifies signal reception due to the peculiarities of the standard.

Undeniable advantages of third generation devices

From the description of what 3G Internet is, we can conclude its main advantages. The device for accessing the Network is independent and mobile. If you need to move frequently while maintaining a connection, 3G has no competitors. A 3G modem together with a router can be used to use the Network simultaneously by several computers.

Today, the creation of devices with 3G technology is a technological and science-intensive industry. The development of mobile communication standards allows you to use more features in devices that are small, at the same time reducing their cost.
