Today’s communication is very easy. Have relatives or friends who live abroad, just call, text or send messages through social media via cellphones. So easy! Current communication really brings the distant closer.
When viewed in history, the process of communication has become so long as it is today. What is the history of communication from ancient times to the present? Check out the following review:
In ancient times, before there were cellphones and the internet like now, it turns out humans communicate through smoke signals. Smoke signals are the oldest method of communication, which was first used in 200 BC (BC).
The smoke signal was first used to send messages on the Great Wall of China. Then in 150 BC, Polybius, a Greek historian found a way to use smoke signals according to the alphabet. It’s pretty cool, without a cellphone you can still communicate with each other.
In the 12th century, Sultan Nur-ed-din of Aleppo first used doves to carry messages. This dove can be used to send messages remotely, from Egypt to Iraq. Not only stopped at that time, pigeons were also used during World War I & II.
Telegraph is the first communication device that uses electrical signals. The way it works is by sending an electrical signal through a cable which is then translated into a message. In 1844, Samuel Morse first sent a message by telegraph, from Washington D.C to Baltimore Maryland.
Telegraphs are no longer used in the 21st century, but today’s communication tools are the beginning of the tools we use today, such as telephones, fax machines and the internet.
Before the time of the cellphone, there was a time for cable telephone or landline. Most homes began to have phones in the 1950s, and one person could only make one call at a time. Cable telephone certainly cannot be carried anywhere, so it is not practical to use. Wow, what does it feel like, living at that time?
Mobile Phone (Cellphone)
Mobile phones were first discovered by Martin Cooper, in 1973. The first mobile phone weighed two kilograms, not as light and thin as we have today. Years passed, and mobile phones were increasingly sophisticated. One of the breakthroughs from mobile phones was the SMS (Short Messaging System) which was first sent in 1992. Today’s cellphones not only can call and send short messages, but also can access the internet, watch movies, take pictures, and more.
Even so, the development of communication tools is inseparable from the development of supporting networks. When the network is interrupted, all the advanced facilities available on the cellphone cannot be used optimally.
Because of that, network service providers also continue to improve. For example Telkomsel, which now has an Integrated Operation Center (IOC) in Telkomsel Smart Office in Jakarta.
Technology that is supported by three operating functions namely Network Operation Center (NOC), IT Operation Center (ITOC) and Customer Care Command Center (C4) is what monitors the flow of voice, … Read More
