We live and move in the world of information flows, making dozens of phone calls, while not always being in the office or at home, in one way or another confronted with the 3G standard (the abbreviation of the English. "third generation"). Let us ask ourselves: ‘What is 3G phone.”

Europe is guided by a special "dialect" of this standard-UMTS, which is a compromise between better CDMA standard, and has great coverage and the number of GSM subscribers. 3G networks operate in the UHF band, around 2 GHz, with data transmission rate of 1–3 Mbit/s To the basic services of 3G networks classifies voice and data transmission. This critical range of services for low privacy, remembering the previous standard, do not understand what is 3G in phone now. Now transfer data at high speed provides communication of both the business sphere (e-mail, video conferencing, remote access to databases, management of Bank account) and personal interests (games, social networks, multimedia systems, Internet purchases). The transmission speed varies in inverse proportion to the velocity of the object. In the case of finding on the spot - 2048 Kbit/s, when moving with a speed of 3 km/h – 348 Kbit/s, up to 120 km/h - 144 Kbit/sec. Popular among users enjoys unlimited Internet mobile offering them the opportunity for a fixed monthly fee unlimited use of the resources of the global network. Many people wonder, “How to choose operator?” the Answer is simple. First, determine whether you are satisfied with its coverage. Then rate the provider's tariffs. Then make a decision.

Well, if the nearest tower of the service provider is close. When the distance of 10-50 km stable operation of the modem will provide 3G passive antenna. Internal it will increase by 5-10 decibels, but sometimes need an external, more powerful. For this you can use 3G Wi-Fi router. Please note that for the three frequency bands of 3G Internet: 450, 800, 2100 MHz - the corresponding selected modem with antenna.
