The progress of mobile phone technology does not stand still. New mobile communication standards have appeared: outdated GPRS, EDGE, new 3G, 4G is already on the way. But, unfortunately, only residents of megalopolises feel the new technologies in full.
Instructions
Step 1
In a large city, there are many obstacles to good cellular signal reception. These are underground passages, high-rise buildings, metro, the signal decreases even in buses and cars.
There are several ways to amplify the signal and achieve consistent reception.
If you need a little signal amplification, purchase an antenna amplifier. It can be used with any kind of mobile device. The amplifier is small in size (approximately 25 * 35 mm and 0.3 mm in thickness) and is installed under the mobile phone battery by simply gluing it onto the back panel.
Antenna amplifier redistributes electromagnetic energy and increases the power of the transmitted signal.
Cost - from 1000 rubles.
Step 2
To amplify the signal in an office, apartment or basement, install a gsm repeater. It is a bi-directional antenna type amplifier. A repeater is installed outside the building. The principle of operation does not differ from conventional antennas, first the signal is received, then it is amplified, and, directly, the signal is transmitted to the cell phone.
The repeater works in the 900 or 1800 MHz bands, and also supports Damps, CDMA450, CDMA800 frequencies. In the coverage area of a simple repeater, the number of simultaneous calls reaches 12. If we talk about expensive complex systems, the bar for simultaneous calls rises to 100-150.
The cost of a high-quality gsm repeater is about 20 thousand rubles.
Step 3
If the signal amplification from the gsm repeater is not enough for you, install a booster.
The booster is a gsm-standard signal amplifier, the principle of operation practically does not differ from the repeater. The only difference is that the booster sends a signal to only one phone. The maximum amplification of the cellular signal can be achieved by connecting the booster using a gsm wire ("through the antenna adapter"). The advantages of the booster also include the presence of a noise suppression filter and a long signal reception distance (at least 30-35 km to the "tower").
The cost of the booster is from 10 thousand rubles.
