3G is short for third generation. This technology combines mobile communication and high-speed Internet access.
The history of the development of mobile communications
The first mobile devices launched into mass production were radiotelephones, which belonged to the first generation of 1G cellular communications. They had the NMT standard and appeared on the world market in 1981.
The next stage in the development of mobile telephony was the appearance in 1991 of the second generation of 2G cellular communications, namely the GSM standard. A feature of this standard is better communication due to sound digitization. A significant disadvantage of GSM is the need to accommodate a large number of base stations, as well as a low data rate within the standard, which does not allow the transmission of high quality sound and video.
To solve the problem of a narrow data transmission channel of GSM networks, the GPRS standard was developed, which became intermediate between second and third generation networks. In fact, this standard is a superstructure over GSM, designed to make the use of the Internet more accessible. It can provide data transfer rates up to 114 kilobits per second. Later, the EDGE standard was developed on the basis of GPRS, providing data transfer rates of up to 474 kilobits per second.
In 1999, the International Telecommunication Union ITU developed the third 3G mobile communication standard, which is called IMT 2000. This standard provides a data transfer rate of at least 144 Kbps for subscribers with a high speed of movement and at least 2.048 Mbps for fixed objects. …
Benefits of 3G connectivity
Due to the high speed of data transmission, 3G communication allows subscribers to make video calls, use various multimedia services that require high data transfer rates, as well as use wireless high-speed Internet services.
The main distinguishing feature between second and third generation networks is the so-called individualization - assigning each user their own IP address. Another key feature of the 3G standard is traffic billing, not time.
The advantages of the 3G standard can hardly be overestimated - huge amounts of data have become available to subscribers of the network, the need for long waiting times for page loading and large files has become a thing of the past. It is time saving and convenience that are the main positive qualities of 3G networks. In addition, it is precisely mobile communication that allows the user to have access to high-speed Internet at any point in the mobile network.
