Rae Young, Bell Labs engineers projected the hexagonal cells for mobile phones. The portable phones were first launched in the early 80's, only the rich people had them. Those phones were very large in size and weighty. It cannot be carried in your packets or purse as now. Its weight around few pounds approximately.

Even though it is big in size, voice clarity was not good and irritates to use. Actually, all these phones were designed to set up in the vehicles (Car Phones). Later, the bulky phones were converted to "Portable" phones. The first portable phones were launched by Motorola and it is handy to use. In 1990, United States introduced the first digital cellular phone which is considerably small in size. The only sole purpose of using cell phone is to provide the people to receive and make call even when they are in the road.
