Mobile phone technology has come a long way since the first mobile phone call was made 40 years ago – but there is a lot more innovation ahead, according to one expert.
It was on 3 April 1973 that Motorola employee Martin Cooper made a call in New York on a Motorola DynaTAC – dubbed a "brick" due to its size and weight – which was widely regarded globally as the first public mobile phone call.The device was 9 inches tall, comprised 30 circuit boards, had a talk-time of 35 minutes, and took 10 hours to recharge.
Four decades on, a worldwide telecoms industry with annual revenues of £800bn has grown rapidly based on wide choice, falling prices and an array of technologies, resulting in the average mobile being used to take photos, play music and games, send emails, download maps, watch video clips, all as well as talking and texting.
The first decade was a research or a 'demonstrator' phase, rapidly followed by analogue networks deployed over 10 years from the early 1980s largely based on carphones and used in business in the developed world."
This soon led to the digital decade mainly between 1993 and 2003 when consumerisation and globalisation of mobile really took off."This led to a further data adoption phase with the arrival of 3G and during 2003 to 2013 access to the internet and the wider use of smartphones became a reality,"
I can bet there would even be more changes, especially towards data as opposed to voice.
