Gone are the days when one has to go home first before he can use the telephone or go to a public phone booth to place an all-important call to a loved one or business contact. With the presence of mobile phones, everyone has now gone wireless. Communication has, indeed, turned very easy for all.

Mobile phone, as it name suggests, provides mobility. It is portable communication device. One can bring it anywhere. It is made possible by satellites that transmit signals for the phone to send and receive. It is very convenient as one can use it anywhere irregardless of time and region.

People everywhere have seen the evolution of communication technology. From a phone that uses wires to one that no longer requires any. From the analog to the wireless. In some places, wireless phones were provided with signals by the network company. In other places, a simulated card in inserted in the phone to grab and receive signals and send as well. These phones use the concept of signal transmission and radio wave theories that enables a two-way communication with real time and clearer conversation.

From the analog mobile phones that only allowed calling and voice conversation evolved the mobile phones that have text messaging features. It is another emergence in the world of mobile technology. A person may send a text message that will be received by another party. This message is sent through a signal passing to a gateway which transmits it to the receiving party.

In the turn of the 20th century, mobile phones have become more of a trend and companies have started to make them appear more sophisticated. Mobile phones started with big sizes which transformed to smaller ones and then became bigger again. It has developed much like how computers have. Nowadays, mobile phones are not just for communication. Originally, it had the voice call function but since the technology is growing day by day, the mobile technology grows along with it. Mobile phones now have been created with different functions and usage which are beyond plain communication usage. These functions are constantly updated and additional features are created each day.

Mobile phones also serve as mp3 players and/or audio, video file storage units where users may save audio files and listen to the music. Mobile phones now are also equipped with cameras that come in different pixels allowing people to take pictures anywhere and anytime. Almost all mobile phones of these times are designed with games, calculator, organizer, alarm clock, dictionary and many more. These are just now considered the basics. Some updated mobile phones may now take video clips and still photographs of which may be transferred to the computer for different purposes. Many mobile phones are also designed with touch screen features where a person doesn’t need to touch the keypad anymore. The screen of the phone is designed to recognize commands as the finger tip touches the screen.

GPRS is used to transmit IP packets which enable users to use the internet wherever they go. People also use their mobile phones in banking transactions where they can send and receive money through phone.

Several high technology features are continuously being researched and applied to mobile phones. Not long ago when 3G system was developed. It enables users of the same networks call each other with real time camera. Through this system, one can actually see the person he is calling while talking to him. Long before people finally get familiar with the just launched 3G system, many companies are now researching on the higher system which is the fourth generation or 4G system. Researchers project the new system as faster with a connection speed reaching 100 Mb per second. This is seen to provide a better quality of call.

Mobile phones are not only for personal use like it was in the past. With mobile phones, reporters and journalists may now take and film news reports. Security system and surveillance are also possible.

It is seen in the near future that mobile phones are most likely to replace laptops.
