The modern telephone is the result of work of many people. In the 1870s, two inventors Elisha Gray and Alexander Graham Bell both independently designed devices that could transmit speech electrically, the telephone.
The history of cellular phones is considered as one of the important evolution in technology. ITs started from a Early cell phones were just for talking. Gradually, features like voicemail were added, but the main purpose was talk. Eventually, cell phone manufacturers began to realize that they could integrate other technologies into their phone and expand its features. The earliest smartphones let users access email, and use the phone as a fax machine, pager, and address book.
Before the mobile phones existed, there were some ancestors. Professor Albert Jahnke and the Oakland Transcontinental Aerial Telephone and Power Company claimed to have developed a wireless telephone. They were accused of fraud for claiming the invention and charge was dropped. Beginning in 1918 the
During the Second World War, the military use of radio to contact and communicate in enemy lines. This is the Hand-held radio transceivers have been available since the 1940s. Telephones for automobiles became available from some telephone companies in the 1940s. Early mobile devices were bulky, consumed so much power and battery, and connection was supported only a few.
By the 1960s, Bell Labs engineers Richard H. Frenkiel and Joel S. Engel developed the technology design of a cellular network. But as AT&T sought permission from the Federal Communications Commission (FCC) to develop a cellular network, a competition ended a bold and rude move in 1970s.
The first mobile were first invented in 1983. Martin Cooper, the executive with Motorola, one of AT&T's competitors. Cooper led a team that designed the first practical cell phone. It was called the Motorola DynaTAC 8000x otherwise known as the “brick” because of it was 9 inches (22.9 centimeters) long and weighed 2.5 pounds (1.1 kilograms).

The first touchscreen Personal Data Assistant (PDA) and combination of phone were built in 1992 of IBM Simon Personal Communicator. Almost a decade, here comes Nokia 3510i that feature a colored screen in 2002. In 2007, Apple create the first truly smart phone, the iPhone that change the way everyone thinks about mobile technology. The competition of smart phones becomes competitive, Google create and design their own operating system, the Android. It is quickly dominates the entire market.
The mobile phones, became a pop culture symbol, showing up on everyone. As the technology advanced, cell phone companies figured out how to pack all the features their customers wanted into a smaller, portable, more affordable model.
