The history of proto mobile phones goes back to 1908 when a US Patent was issued in Kentucky for a wireless telephone. Mobile phones were invented as early as the 1940s when engineers working at AT&T developed cells for mobile phone base stations. The very first mobile phones were not really mobile phones at all. They were two-way radios that allowed people like taxi drivers and the emergency services to communicate.
All that changed on April 3rd of 1973, when Martin Cooper, a Motorola executive, made the first handheld cell phone call. The guy he rang was his rival at Bell Labs. Cooper’s phone weighed in at just below 2.5 lbs (1.1 kg). Its battery allowed a half-hour of use, and then, 10 hours of recharging later, it would be ready for a chat again. These early mobile phones are often referred to as 0G mobile phones, or Zero Generation mobile phones. It would be another six years before the launch of the first — 1G — cellular network, and then only in the center of Tokyo. By 1984, the network had expanded sufficiently to cover the whole of Japan.
In 1983 Motorola launched DynaTAC 800x, developed at a cost of $100 million. It was priced at around $4,000 and lasted for 30 minutes of talk time before dying. It looked like a brick, and a brick is what people called it. Despite the phone’s large size, it was still considered to be the most portable telephone ever made. For the first time in history, a human being could call someone without the constraints of wires or portable phone holders.
It wasn’t until the 1990’s that developers started to release a 2nd generation of mobile phones. In 1992 the IBM Simon was released, this phone is considered the first ever smartphone. The phone acted more as a planner with the added ability to make phone calls. You could create task lists and store contacts, but that was all that Simon could handle. This hand held device retailed at around $900 and sold close to 50,000 units. Simon essentially paved the way for many smartphones to come.
