How do telecommunications work?


You've probably heard the word telecommunication, even if you're not quite sure what it means. You may have understood that it's important, but you may not know what it's for. Let's understand how telecommunications work. Before we start, it is important to highlight that you already knew about them and they have been changing your life for years.

Define telecommunicationes

A telecommunications network is the set of all the systems necessary for the exchange of information between users connected to the network. We mainly describe them as telecommunications when they are instantaneous, have the power to connect users over long distances. We talk about telecommunications when we mention techniques or services that use technological advances to exchange large amounts of information through internet connections.

Nowadays, the facilities that make it possible to take advantage of Internet communications are part of the basic infrastructure. Any town, institution or home has some type of telecommunications connection or service. This is because nowadays much of our social, economic, political and cultural interaction is strongly associated with being able to communicate over long distances with complex information.

Connection and telecommunications

Today these are the keywords of the digital world. Millions of businesses are closed or lost because of the speed of their connection. An entire ecosystem of services is offered by both Internet providers and internet-based and internet-dependent services. Political or ideological movements are transmitted around the world thanks to internet images.

Nowadays, telecommunications reign among the technologies we use. Whether to talk on a landline or cell phone, to watch television or videos on the Internet, or to check memes on social networks. No one escapes the constant presence of some form of physical or wireless communication.

Some History

Telecommunications facilities that are available today, are different from the telegraph and telephone systems that were invented in the 19th century. The invention of radio in the late 19th century allowed greater distance and frequency for communications. Later, wireless telegraphy (also called radiotelegraphy) was developed in the early 20th century to allow messages to be sent and received by radio. These two techniques led to a more accessible communication platform. In addition, the development of the telephone in the 1890s allowed people around the world to talk to each other, changing the dynamics by which the world interacted.

LDTeleCom Function


A telecommunications system consists of three main parts: transmitter, receiver and communication medium. The transmitter is where the information is generated or formulated before being sent through electromagnetic waves. The receiver receives the information after it has been transmitted through the use of an antenna or an electronic device that can pick up electromagnetic waves. The media transmits the information between the transmitter and the receiver; it can be used to transmit voice, data or video information.

We are providers and intermediaries that make sure that the best services reach where they are most needed. We seek to maintain contact with the main companies that provide internet and telephony services, and we form alliances. It is through these alliances that we are able to provide small and medium sized companies with key services for their development.


Thanks to our vision, today we reach more than 200 countries using a network of more than 100 affiliated companies. We currently operate points of presence (POPs) in the United States, Venezuela, Peru, Brazil and Spain, where we support the best IP gateways.
