Telecommunication equipment refers to equipment primarily used for telecommunication, such as transmission lines, multi-channel, and base receiving stations. It encompasses different types of communication technologies include phones, radios, and even computers.
Since the early 1990s, the line between telecommunications equipment and computing equipment has been blurring as the growth of the Internet has made telecommunications infrastructure increasingly important for data transmission.
Basic to understand about Telecommunication:
The telecommunication system consists of three units
- A transmitter that receives information and converts it into a signal.
- A transmission medium called a physical channel; transmits the signal.
- A receiver that records the channel signal and converts it into useful information.
Telecommunication by telephone lines call;
- Point-to-point communication between the sender and the recipient.
- Transmission communication between the power transmitter and several low power receivers.
Digital communications purpose:
The communication signals can be analogue or digital. The analogue signal has constant changing in terms of information.
In the digital signal, the information encodes in a binary language. During propagation and reception, the information in analog signals inevitably decreases with the noise. And we want the output of a transmitter to be silent for all practical purposes.
What are Communications networks?
A communication network is a collection of transmitters, receivers, and communication channels that send messages to others. Routers send information to the right users. An analog communication network uses switches to establish a connection between the two users. The communication network or switches required repeaters to amplify or reproduce the signal when transmitted over long distances.
How to communicate with other users through the communication networks?
The caller connects to the person with whom he wants to speak via switches in different telephone exchanges. The contacts form an electrical connection between the two users.
The configuration of these contacts determines electronically when the caller dials the number. Once the Connection establishes, the caller is transformed into an electrical signal by a small microphone inside the caller.
This electrical signal is then sent over the analogue network to the user at the other end, where it converts back to sound by a small speaker in the Person cell phone. The separate electrical Associate works in reverse and converts sound into electricity.
Public Switched Telephone Network:
Public Switched Telephone Networks (PSTN) is the world’s circuit-switched public telephone network.
It is a global network of telephone lines, fiber optic cables, microwave transmission links, cellular networks, communications satellites, and submarine telephone cables that are interconnected through central offices and enable any phone in the world to communicate with others.
The PSTN network is fully digital and includes cell phones.
Different types of telecommunications equipment:
Telecommunications equipment includes many types of telecommunications, including telephones, computers, and radios. All of these types of telecommunications networks send signals through a connection to the Internet.
Telecommunications devices depend on software to function. So, depending on technicians who understand the hardware and software components of the technology.
Examples of telecommunications equipment are switches, telecommunications towers, and fiber optic cables, routers, VoIP (Voice over the Internet), and smartphones.
1) Communications Satellite:
A communications satellite is a type of artificial satellite that in orbit to send and receive communications data between a source and a destination. It provides data transmission and broadcast services for television, radio, telecommunications, weather, and Internet services.
2) Telecommunication Towers:
A cell tower, telecommunication tower or cellular antenna is a structure equipped with antennas and other electronic components, transmitters, receivers and power supplies needed to transmit a cellular signal.
When you make a call, your cell phone connects to the nearest available message tower (or the nearest cell phone tree to your service provider network), and the Tower sends your outgoing signal as well as an incoming and outgoing voice. More information on your phone.
It is similar to how a radio station broadcasts music and other radio broadcasts – and the signal from your smartphone uses the high-frequency portion of the electromagnetic spectrum.
3) Fiber optic cable:
A fiber optic cable is a network cable that contains fiber-optic wires in an insulated jacket. It designs for high-quality telecommunications and long-distance networks. Compared to hard-wired Cables, fiber optic cables offer greater bandwidth and transmit data over greater distances. Fiber optic cables support many Internet, cable TV, and telephone systems around the world.
VoIP stands for Voice over Internet Protocol and describes the method of making and receiving phone calls over the Internet. Most people see VoIP as an alternative to the local phone company.
If you’ve heard of an IP address, this is your internet protocol address. An IP address is a way computers and devices communicate with each other on the Internet.
VoIP isn’t new. Telephony has been using digital lines for telephony since the late 1990s. VoIP is a convenient way to handle an unlimited number of calls.
A router is hardware used to receive, analyze, and move incoming packets to another network. It can also convert Packets to another network interface, ignore them, and perform other network-related actions. The image shows the Linksys BEFSR11 Wi-Fi router and looks like many home routers.
6) Smartphone technology:
Old school cell phones can create and send a text. While it targets your message, smartphones give you more ways to communicate with your employees, customers and suppliers.
In addition to making calls, text messages, and instant messaging, these communication tools allow you to access e-mail, instant photo sharing, video calls, and video conferencing. You can organize a staff meeting anywhere you have phone service! You can also stay connected through online sites like Twitter, Facebook, and LinkedIn.
7) Radio transmissions:
In radio broadcasting, a radio antenna transforms a time-varying electric current into an electromagnetic wave or electromagnetic field that propagates freely through a non-conducting environment such as air or space. In a broadcast channel, a radio antenna sends a broadcast signal over a wide service area.
In both cases, the emitted electromagnetic wave picks up by a remote receiving antenna and transformed back into electricity.
I conclude that telecommunications equipment has a crucial role in the development of the communication system. Every type of telecommunication equipment plays its part to run the process of the whole communication system.
