Prior to 1973, mobile telephony was limited to phones installed in cars and other vehicles. Motorola was the first company to produce a handheld mobile phone. On 3 April 1973 when Martin Cooper, a Motorola researcher and executive, made the first mobile telephone call from handheld subscriber equipment, placing a call to Dr. Joel S. Engel of Bell Labs. The prototype handheld phone used by Dr. Cooper weighed 1.1 kg and measured 23 cm long, 13 cm deep and 4.45 cm wide. The prototype offered a talk time of just 30 minutes and took 10 hours to re-charge.
Modern cell phones are capable of much more than just sending and receiving phone calls. Mobile phones used in today’s world allow users to send and receive text messages, emails, photos and video as well as access the Internet, play games, listen to music, use GPS (Global Positioning Systems) and more. The cell phone has become an important communication tool that is used by people all over the world to keep in contact with each other at any time. Although they started off as quite bulky devices they are now very sleek, small and portable, comfortably fitting in a users pocket and surviving for hours on end thanks to a rechargeable battery.
A smartphone is a mobile phone with an advanced mobile operating system which combines features of a personal computer operating system with other features useful for mobile or handheld use.
