First mobile phone call (1973) : 'Hi Joel - guess where I'm calling from?'
Dr Martin Cooper, a former general manager for the systems division at Motorola, is considered the inventor of the first modern portable handset. Cooper made the first call on a portable cell phone to his rival, Joel Engel, head of research at Bell Laboratories.
Bell had introduced the idea of cellular communications in 1947 with their police car technology and had been racing to beat Motorola. But in the end Motorola was first to incorporate the technology into a portable device designed for use outside a vehicle.
The origins of mobile
Mobile telephones had been around for almost 60 years before we got our first cellphones in the 1980s.
To start with there were radiotelephones for ships, aircraft and military vehicles. Then radiophones for cars and finally personal mobiles.
The theories for cellular mobile telephony were shaped by the 1940s - but getting there would take a further 40 years
