Basic Elements of Telecommunications Systems

What are the basic components of  telecommunications systems.Telecommunications pervade our daily lives. Many people wake up to their radio alarms, open the TV to get traffic and weather updates, and perhaps telephone their car pool buddies just to make sure they won’t miss the ride. At the office, they boot their computers to check if they have emails or some other business documents delivered. All these are forms of telecommunications, and it is obviously something that no modern society can do away with.

Telecommunications actually rests on very simple elements –a sender or transmitter, a medium or channel, and a receiver. It is the transmitter that converts the message or data into electrical impulses or signals. These are carried away from the transmitter on a medium, which could be copper wires, optical fibers, or the free space channel. A receiver then copies the electric signal and converts it back into the same form it was entered into the transmitter.

A simple illustration of this is a radio broadcasting station that uses a power amplifier to convert music into electrical signals which are sent up to an antenna. The antenna interfaces with the free space channel using light propagation. The electric signal is caught by the antenna of a radio tuned to the same frequency and is sent to the receiver where it is converted back into vocal or musical sounds.

Because your radio can only receive signals from the radio station, the communication is termed one-way or simplex. Your cell phone, however, because it can receive as well as send out signals, is a two-way or duplex device. It is alternatively referred to as a transceiver. Systems that involve multiple transmitters and receivers, such as those used by the police, are called multiplex systems.

The transmission of signals from radio to TV stations, because it is sent from one powerful transmitter to a multitude of radio or TV sets, is termed broadcast telecommunications. That between two cell phones, on the other hand, is called point-to-point telecommunications.

A World Without Telecommunications

If telecommunications facilities break down.Radios, TVs, cell phones, and the Internet are now deeply embedded not only into our economic systems but also into our personal and social lives that it is difficult to imagine what would happen if all telecommunications systems broke down at the same time.

Many businesses have gone global, sourcing not only physical products but services as well from countries all over the world. Coffee companies in the US, for instance, buy their beans from Brazil and Colombia, and even as far away as Vietnam and Indonesia. With no way to get in touch with their overseas suppliers, coffee processors would run out of raw materials.

The most commonly outsourced service is that of a call center. Indeed, call centers proliferate in the Philippines and India where local salaries are lower than in the United States. This constitutes savings for the American business. This, however, is heavily reliant on efficient telecommunications systems.

Even for companies that do not outsource their business processes, an efficient telecommunications infrastructure is equally important. Think of all the stores that rely heavily on online sales. Without the Internet, sales would plummet. For Amazon, this would drop to zero. Even the sales of Domino’s, Little Caesars, Sbarro, Shakey’s, or Pizza Hut would most likely drop without telephones and the Internet.

It is not only businesses that would suffer from a lack of telecommunications systems. Individuals would be greatly affected as well. Imagine not being able to have your pizza delivered to your doorstep. TV entertainment would have to be limited to your Blu-ray discs, and while you can play video games, you can’t compete against remote players.

Perhaps the worse part is that getting in touch with family and friends would become more difficult. With Facebook, Twitter, and Skype on the Net you can get in touch with them wherever they are in the world at any time of the day. Without them, you will have to go back to the good old snail mail.
