Evolution of mobile phone

The history of mobile phones can be traced back to the late 19th century, when communication through wireless telegraphy was first developed. However, the first mobile phone as we know it today was invented in 1973 by Martin Cooper, an engineer at Motorola.

Cooper's device, called the Motorola DynaTAC, was a brick-shaped mobile phone that weighed 2.5 pounds and cost $3,995. It could only make phone calls and had a battery life of 30 minutes.

In the 1980s, mobile phones became more widely available, but they were still expensive and bulky. The first commercially available mobile phone was the Motorola Dyna TAC 8000X, which was released in 1983 and cost $3,995.

In the 1990s, mobile phones became smaller and more affordable. Nokia became a dominant player in the market with its range of popular devices, including the Nokia 3210 and Nokia 5110.

The 2000s saw the introduction of smartphones, which combined the functionality of a mobile phone with features like email, internet access, and a camera. The first smartphone was the IBM Simon, which was released in 1993, but it was the introduction of the iPhone in 2007 that really revolutionized the market.

Today, mobile phones are an integral part of everyday life, with over 5 billion people using them worldwide. They have transformed the way we communicate, access information, and interact with the world around us.
