In order to understand what 4G is in the tablet , let's first learn a little more about this fourth-generation protocol. The abbreviation "4G" comes from the English word combination fourth generation, which means "fourth generation". In this case, it is a generation of a wireless data transmission channel. In order to possess the 4G standard, the communication operator is obliged to transmit data at a speed of 100 Mbit / s. Let's see what advantages the owner of a tablet with support for the 4G protocol can get.
General requirements
As mentioned above, for a communication channel to be assigned a 4G status, it must provide a connection speed for the user from 100 to 1000 Mbps. To date, there are only two technologies that are assigned the status of 4G. The first one is Mobile WiMAX Release 2 (IEEE 802.16m), and the second one is LTE Advanced (LTE-A). In Russia, tablets supporting 4G receive and transmit data on LTE technology. To date, the actual data transfer rate is 20-30 Mbit / s (measurements within Moscow). The speed, of course, is much lower than stated, but for owners of portable devices this is quite enough. Now let's learn in more detail what 4G means in a modern user's tablet.
Advantages of 4G tablets
First of all, gamers should be happy, because with the increase in connection speed, ping dropped significantly (communication quality improved), which makes it possible to play from the tablet even in such capacious multi-player video games as "Online Tanks". Holders of the tablet with LTE (4G) support can watch streaming video in high quality, almost instantly download music and media files. At the moment, many devices have been released that support the new protocol. In the future, significant investments are planned for the development of 4G coverage in Russia. As you can see, the technology of data transmission of the fourth generation has become a real breakthrough in the provision of Internet services for mobile device owners. Obviously, soon the connection speed will increase even more, the coverage area will increase significantly. When asked whether 4G is required in the tablet in your case, the answer will depend on whether there is a 4G coverage in the territory where the device is planned to be used. In addition, it depends on your willingness to part with an impressive amount, because while these devices are not cheap, like the service itself.
Disadvantages of 4G
It is well known that a tablet with a 4G channel has several unpleasant properties and differences when compared with devices with an earlier 3G protocol. The most annoying thing is that the presence of both protocols (3G and 4G) in the gadget leads to the fact that using a more modern one reduces the battery charge by 20% faster. In addition, I want to complain about the terrible quality of the service itself (the speed of the Internet), because it is five times lower than the declared lower threshold. Many countries have long overcome the speed of 100 Mbit / s., And
On the question of whether to buy a tablet with support for 4G now, there is no definitive answer. If you want to play online games on the way to the institute or office for $ 30 a month (cheaper packages for games are not relevant), then why not. The main thing, do not forget to carry a charger with you all the time, because batteries (even very good ones) sit down for a maximum of four hours.
