Since its first use 40 years ago, the mobile phone has completely changed our lives. The first decade was a research or a ‘demonstrator’ phase, rapidly followed by Analogue networks deployed over 10 years from the early 1980’s largely based on car phones and used in business in the developed world. Next came the digital decade, mainly between 1993 and 2003, when consumerisation and globalisation of mobile really took off.

Four decades on, a worldwide telecoms industry with annual revenues of £800 billion has grown rapidly based on wide choice, falling prices and an array of technologies. Dr Mike Short past President of the Institution of Engineering and Technology (IET), and mobile industry veteran, says the coming years will see mobile innovation continue to change our lives. He says “With close to 7 billion customers today, we already expect this year globally more mobile devices (or subscriptions) than people”
