Communication has become an important element to human beings since their existence on earth. It is used to deliver and receive data among each other (interaction). Since communication becomes a need in human life, therefore a revolution of communication keeps expanding.
At the earliest stage, the way of communication is by using smoke and drum sound. Back in the time, when people saw the smoke or hear the drum, they will know something is happening. When they received the signal, people will rush to community centre to find out what exactly happened. This kind of communication has few weaknesses and people start inventing something more reliable than this.
After that people come out with mechanical devices. Everyone must hear the technology of ‘Cup Phone’ before. It just about two cups and attached with a string. This method could transmit greater distance rather by speech. In addition, this kind of communication was very popular used for aboard ship and for lovers. Well, using cup phone may save your budget to pay the bill.
An electric based phone invented after using mechanical method. At the earlier stage of this revolution the machine only transmit the data by writing and voices. The machine called ‘Telegraph’. An actual telephone using voice invented then and it keeps growing up. From this kind of technology, the telephone keeps developed to become fancier, smaller, lighter and modern.
If you still remember few years ago on how was the phone invented. It comes without any screen and just basic numbers and ‘pick up & hang up’ button only. Then it comes with screen even it is not colourful but good enough to store phonebook and see the call history. From this kick start, the mobile phone becomes fancier equipped with a lot of useful stuff.
Sometimes, you might be wondering how this mobile phone works nowdays. As the previous posting, I already explained to you what is the purpose of a Geo-Stationary satellite? That is the basic method implemented on the technology. You may see how the data (communication) sent and received by refer to it.
Now, let us see how is a mobile phone nowdays looks like? Obviously you might find a colourful screen to please owner in watching video and review pictures. Plus most of the phone nowdays equipped with camera! It is really cool isn’t it? You might want to take pictures and video just by bringing your phone! Second of all, it also stuff with the GPS technology. It means just by bringing your phone, you won’t be lost anymore.
There was a lot of fun stuff equipped in a mobile phone nowsday. For the next post, we will review the function of a mobile phone and what is the technology implemented in it. This kind of modernization just to prove you that engineers are struggling to provide us a better living.
