How does the base station work?

The base station consists of a transceiver, an antenna, one or more installed on a special tower, as well as auxiliary equipment. But this of course, the simplest version of how the cellular communication is organized, and with it other types of wireless connection.

Base stations: what are and how they work

There are many ways to implement such BSs. And the description of some of them resembles the equipment of James Bond from the movie about the famous spy. So, a simple small case can quite contain inside everything necessary for the work of a small office, such base stations are called: femtocells, picocells. Their main purpose is to improve the quality of communication at specific points. The work of such cases can be used to improve the quality of communication between border zones, places where the operator is unstable, but it is not advisable to attract more serious resources.

More classically, the base station represents a small box with special equipment, where one or several towers with antennas are installed side by side (the latter can also be installed on roofs, walls of houses, hiding in the crown of trees, etc.).

Antennas and towers: urban locations

When an ordinary wireless Internet or mobile phone user sees such equipment, he has clear doubts: can find a person by Mobile phone , as shown in the movie? However, let us hasten to assure that the interiors of ordinary-looking boxes are blocks 2 and 3G. They provide communication antennas and switches that distribute incoming calls in all directions, as well as serving the Internet connection for users (respectively).

However, honeycombs can be combined, then single boxes are transported inside the carriages, where motion sensors, temperature controllers and fire fighting equipment. Additions to this remain antennas, which for one object can be more than 5, 8, as the capabilities of the specific equipment allow.

Urban communications do not allow so much to stand on ceremony with a huge number of towers, they are actually replaced by the roofs of houses, and all the contents of the trailers fit perfectly in attics or even in the entrances of houses.

For full-fledged operation, antenna-feeder devices (APS), low-noise amplifiers, radio relay communication lines are involved. But anyway, all the signals after special processing are sent to the switchboard, one of which is inevitably connected even the most antediluvian smartphone. Such a bundle allows using the NetMonitor program to determine with a high enough accuracy the location of a specific (even an optional included phone).

Control or financial need: to know the coordinates of the employees’ stay

It’s much easier to find people when the phone has built-in GPS or WiFi modules. In the latter case, the error is calculated in several meters. The program database contains information about the location of the network cells, the list of access points. Files with registration data are written in CLF or KML formats, which allows you to track the user on a SIM card or electronic device.

Using NetMonitor for the GPS module, they optimize the logistics of the enterprises, since you can track the location of a particular device at certain intervals. Also, the program allows you to adjust the movement of the employee in real time, this is especially true for the courier service.

However, such actions would not be possible if the coordinated operation of the base stations connected by the controller to which data about all the movements of users in the radius of coverage of one or several cells are transmitted.
