Exactly 45 years back, the world witnessed the creation of today's greatest weapon to communicate over long distances. In 1973 on April 3, Martin Cooper, a senior engineer at Motorola made the first public mobile phone call using Motorola DynaTAC in New York.

Now recognised as the "father" of a mobile phone, Martin called a rival colleague at another telecoms company and announced he was speaking from "a 'real' cellular telephone". Unlike the 70s, we can't imagine our lives without mobile phones today.

Interesting, the Motorola DynaTAC was dubbed a “brick” – it was huge and bulky. They didn't come into use until 10 years later and that too at a high price, making it unaffordable for the major sect. Priced at $3,995 with 1kg of weight and 10 inches length, the phone comprised 30 circuit boards.

The historical device at a talk-time of 35 minutes and took 10 hours to recharge. Over the years, mobile has developed way more than just a device to communicate. Today's mobile phones have incorporated access to the internet and other services, making the device way more useful.

Before the hand-held mobile phones came into use, car phones were used as a mode of communication by senior government functionaries and elite group in the 40s and 50s. The car radiophone service network was connected to the car's battery.

The car phone service used signals that were attached to telephone networks and worked on high power transmitter and external antennas to get their signals across. The cell towers were developed to receive signals in three hexagonal directions which powered the car phones.
