What makes a good telecom company?
The financial statements of companies are of general interest, especially for the clients of these companies, as they offer us the possibility to evaluate whether or not a telecommunications service provider has the necessary resources to ensure the constancy of a service.
Telecommunications systems are technical means designed to transfer large amounts of information through fiber-optic communication lines. Usually, telecommunications systems are designed to serve a large number of users: from a few tens of thousands to millions. The use of such a system involves the regular transfer of information in digital form between all participants in the telecommunications network.
The main feature of modern network equipment is to ensure uninterrupted connection so that information is transmitted constantly. At the same time, a periodic deterioration of the communication quality is allowed when establishing a connection, as well as periodic technical problems caused by external factors.
Types and classification of telecommunication communication systems
Modern telecommunications systems are combined according to several main features.
Depending on the purpose, television broadcasting systems, personal communication systems, and computer networks are distinguished.
Depending on the technical support that is used to transmit information, there are traditional cable communication systems, more advanced – fiber optics, as well as terrestrial and satellite.
Depending on the coding method of the information range, the analog and digital communication channels are distinguished. The latter type has become widespread, while analog communication channels are becoming less and less popular today.
Computer systems are a collection of several PCs, united in a single information field through cables and specialized programs.
The set of installed hardware and software is a self-regulating system that serves the enterprise as a whole.
Depending on its functions, the equipment of the computer system is divided into:
- service (for intermediate and backup storage of information);
- active (to ensure timely and high-quality signaling;
- personal devices.
To ensure the operation of the entire system, appropriate software is required, properly configured based on user needs.
Radio and television systems engineering
At the heart of the radio-technical message transmission systems are electromagnetic oscillations, which are broadcast on a special radio channel. The unit of operation of the system is a signal that is converted in the transmitting device and then transformed into an information message in the receiving one.
The basis of the uninterrupted operation of radio engineering systems is the line of communication – the physical and hardware environment that ensures the timely and complete transmission of information.
Television systems operate on a similar principle of receiver and transmitter. Most use a digital signal to transmit the message at a higher quality.
Global telecommunications systems
Global telecommunications systems are those hardware and software that connect users regardless of their physical location on the planet. The main feature of WANs is intellectualization, which makes it easier to use network power with optimum efficiency while reducing equipment maintenance costs. There are several main types of global networks.
Optical telecommunication systems
The basis of optical telecommunications systems is a fiber optic cable that connects individual devices in a single global network.
The signals are transmitted using the infrared radiation range, while the capacity of the fiber optic cable is often higher than that of other types of equipment.
Speed and coverage
Two parameters that play a major role for consumers dedicated to choosing a mobile internet service are the speed and coverage of the cellular network.
