Mobile cellular communications: how does it work?
Writes blogger gelio-nsk:
Every day we talk on the phone, SMS and helmet use mobile 3G-Internet. All this time we have served mobile operator, SIM-card is in our phone, smartphone or communicator. In the few minutes that are from the beginning to the end of the conversation, the digital signal is supplied from our phone to the base station, the switch is processed, and its value is calculated special billing system. Information about our calls are stored on a dedicated server, at any moment we can see the details of their conversation. For this and many other equipment working around the clock to communication is not stopped for a minute.
For example, a cellular company, I will try to explain the work of the mobile operator from within ...

2. The base stations.
Installing the base station to the antenna mast structures (AMS) - the most effective way to provide communication track and a large area outside the town.
3. The height of the antenna mast constructions can reach 85 meters.
4. The antenna mast structures of medium size can be mounted on the roof of a large building.
5. AMC in accordance with approved procedures several times a year are censored.
6. Data Center - a comprehensive technological platform, located in the Cotorro computing and telecommunications equipment, as well as all the necessary air conditioning and fire suppression.
7. The group of telecommunication devices include a switch, base station controllers, traffic exchange sites.
8. The computer equipment consists of industrial storage of large volumes of information, billing and other high-end servers that are engaged in high-precision calculations.

12. Switch - the "heart" of any operator.
There is processed all subscribers of MegaFon made outgoing calls and incoming calls from other networks.
13. Switches cellular companies are connected with each other, and it allows millions of people to communicate with each other, even if they are served by different mobile operators.
14. inconspicuous gray cabinets hidden base station controllers.
This equipment is responsible for the interaction of the base stations with each other - for example, to a subscriber conversation is not interrupted when moving out of range of one base station to coverage area of another transmission apparatus.
15. For communication between the nodes of the data center using an optical (laser) high bandwidth cable. Each channel of the cable in the composition is less than the thickness of a human hair.
16. Powerful servers billing system are responsible for the calculation of the cost of services consumed by the subscriber.
17. Every second billing processes more than 300 calls, 400 SMS and 40 GPRS-sessions.
And he does all this in a short period of time between the dial and the first ring in the tube.
18. All the equipment of the data center is installed on a raised floor.
19. The design of raised floor above the normal surface of the floor space by 70-100 cm, to underneath could spend all communications and cooling system. 1 square meter of the raised floor can withstand loads of up to 2, 5 tons!
20. This cabinet consists of 48 small but powerful Blade-servers.
Each server is several times the computing power of a home multimedia computer, and the entire cabinet allocates up to 25kW of heat per 1 sq. m.
21. In the data center servers using special hard drives other than hard drives for office or home computers.
22. They differ significantly higher speed, reliability and price.
23. In order to cool the data center facility used precision (extremely accurate) air-conditioning systems.
One such device takes up no more than one and a refrigerator is at 30 conventional power conditioners installed in flats residents.
24. Cooling air conditioners for industrial data center chiller installation is carried out.
For its size and the largest reservoirs is comparable to a small plant for the production of carbonated water.
25. In the industrial premises of the mobile operator uses a gas extinguishing system, similar systems on nuclear submarines.
26. In case of fire being bottled gas is expelled in a few seconds and displaces oxygen from the room - the main source of the combustion process.
27. The main distribution range of data center provides power to telecommunications equipment, and contains massive batteries that are needed in the event of a power failure

29. Office Express Service.
30. The Office Express Service subscribers can connect to the network, update your account, set up the phone, get qualified professional help.

33. Monitoring Center network.
It is intended to gather information about the activities of most of the components of a mobile network in 9 regions of the Russian Federation.
34. The Centre operates around the clock and there is always a change of duty to promptly proeagirovat maskiimalno any possible nepoladkki.
35. On 32 large monitors of the Center management and monitoring of network information is displayed on the work of thousands of base stations, long-distance communication lines and even the speed of receiving payments from customers.
36. Call-center.
37. Contact Center subscription service
One employee per shift center is responsible for about 300 calls customers.
