3G (disambiguation). third generation) is the technology of mobile communication and packet communication of the third generation that works in the UHF frequency range. 4G (disambiguation). fourth generation) is the next — generation technology, with higher speed performance. To connect to 3G or 4G requires a special modem. Mobile devices equipped with built-in modem.
The main difference between these two technologies lies in the speed of data transmission. And modems 3G will have a lower cost. 3G network capable of transmitting data at a different rate, which depends on the working frequency of your mobile operator. The higher the frequency, the greater the speed. For example, operators MTS, Beeline and MegaFon, the working frequency is 15 MHz, and the Skylink is only 4.5 MHz. So at the moment the faster 3G Internet at the above three operators. As for the speed, it ranges from several hundred kilobits to several tens of megabits.
4G supports data transfer speeds more than 100 Mbps for mobile devices (modem built in). USB modems for fixed devices may operate at speeds of 1 Gbps.
The main advantage of 3G is coverage of a large area. This technology is supported by almost all mobile devices. But for desktop computers, netbooks and laptops can use USB 3G modems.
As for disadvantages of this technology, they are associated with a relatively low speed performance. Therefore, the 3G Internet is only suitable for those users who do not need to download large amounts of information at high speed.
3G Internet works fine in the city, and the possibility of its use depends on the coverage area serviced by the mobile operator. Data transfer rate outside the city may be lower.
The device has a built-in 4G modem, for high-speed data transfer have a higher power consumption. But for desktop computers you connect an external USB modem, this is not a problem. And for users of mobile devices creates additional difficulties, because smartphones and tablets will be quickly discharged. If you need mobile Internet while traveling, it is better to use a 3G modem.
4G networks do not have wide coverage and are just starting to develop actively. So it will take some time to 4G networks was available everywhere. The disadvantages of 4G can be attributed to the higher costs of mobile devices that support this technology. As for 4G modems, you can connect to any desktop computer or laptop through USB slot.
