Almost any modern gadget, be it a netbook, tablet, e-book, becomes almost meaningless without access to the Internet. Many of them have built-in modems that do not require additional devices except a SIM card to connect to wireless Internet.
What is a built-in 3G modem
3G modem is a third-generation data transmission standard (3-Generation), operates at 2 GHz, the maximum data transfer rate is 3.2 Mbit / s, although the final result depends on the tariff you choose.
The built-in 3G modem is a device with a slot for a SIM card, found in almost every modern portable computer device. It is easy to activate it - just insert a SIM card and you will get access to the Internet.
3G Internet
The stability of the Internet signal transmitted using a 3G modem depends on many factors. In fact, such an Internet works on the principle of the mobile Internet familiar to everyone, one has only to choose the tariff correctly. Note that the signal will be better where the network coverage is more stable. Coverage area refers to an area where an uninterrupted signal is maintained for a long period of time. All mobile operators today have stable network coverage areas almost anywhere, including outside the city. Less reliable is the Internet provided by the Tele 2 operator. Insufficient network signal stability is fraught with the fact that the Internet connection becomes slow, and sometimes even disappears. This deprives the user of the ability to view video files as well as listen to music.
Signal stability depends on the base station, how far away it is from the Internet user. The further - the less coverage area, respectively, the signal quality drops rapidly. In addition, the frequency range (it is he who determines the channel capacity), intended for 3G networks, is not wide enough to provide the data transfer rate supported by the 3G standard for all clients. 3G networks, unlike previous generations of communication, do not subdivide voice communication and data transmission services into more or less priority ones. That is, if many users of one base station start talking on the phone, then the Internet will have all the remaining speed.
MTS, Beeline and Megafon - the three largest mobile operators - provide Internet via 3G at virtually the same level. Of course, the development of information technologies, in particular, the development of the 3G system, and now 4G, is undoubtedly the future of the Internet, affordable for everyone.
