What are the different types of telecommunications infrastructure?

since its invention, communication technology has always depended on some form of telecommunications infrastructure. In this case, the infrastructure concerns the network of processing centers and devices designed to send electronic signals from one place to another. Early forms of telecommunications infrastructure depended on wires and cables that had to be physically strung at any place, no matter how far away. Modern infrastructure is increasingly using wireless technology that communicates with satellites, signal towers or small local facilities in the house or business.

Before the arrival of electronic communication, any report sent to a remote place had to be delivered manually, which is a process that included great time and expenses. Public and private postal services were supported by innovative approaches such as traffic lights, light beacons or even smoke signals. Each of these methods required infrastructure, previous network set up for processing and deliverythe news. When the telegraph was invented in the 1930s, it also required infrastructure, a network of wires for communication of the telegraph signal. In the 66th of the 20th century, telegraph cables, the first telecommunications infrastructure, were placed in various nations around the world.

Telegraph enabled the delivery of messages at once at a large distance using methods such as Morse Code. The telegraph was replaced by the invention of the phone in the 70s of the 20th century, but the idea of ​​telecommunication infrastructure remains unchanged, even in the 21st century. Although the phone could pass voice information almost immediately at long distances, it still required the infrastructure of wires, cables and human operators. In the 1950s of the 20th century, the ships were installed underwater telephone cables connecting continents, engineering performance, which created the first truly global telecommunications infrastruccure.

Given thatU for decades for decades, simple electronic wires have been replaced by cables with optical fibers. These can communicate more information faster and use light rather than electricity as a medium for signal transmission. This allowed extensive use of fax or fax machines that could transmit documents via telephone lines. Once a worldwide telecommunications infrastructure with optical fiber cables was set up, the Internet has become a possibility. Computer networks used existing telephone lines not only text and images, but also videos, store and complicated interactive websites.

In the 21st century, the telecommunications infrastructure includes mobile phones that can wirelessly transmit a signal to satellites in space if they are at a distance from the relay tower. All over the world were built relay towers, allowing a credit card size device to communicate with any other phone, anywhere on Earth. Wi-Fi infrastructure allowIt sees computers prepared on the Internet to have roughly the same coverage without being directly connected to telephone lines. Instead, they can communicate wirelessly with Wi-Fi transmitters located in many businesses, houses and even distant, previously inaccessible places like Mount Everest.
