"For the period through 2017, the mobile industry will invest USD 1.1 trillion in capital expenditure and will contribute USD 2.6 trillion to public funding. Importantly, in 2017, companies across the ecosystem will employ nearly 10 million people globally," 'The Mobile Economy 2013' report prepared Developed by GSMA and consulting major A.T. Kearney said.
The report said revenue from total mobile ecosystem revenues reached USD 1.6 trillion -- around 2.2 per cent of the global Gross Domestic Product (GDP).
The report said it expects a further 700 million subscribers will be added by 2017 and the 4 billion-subscriber milestone will be reached in 2018 across the globe.
At the end of 2012, there were 6.8 billion mobile connections worldwide and the study expects it to grow to 9.7 billion by the end of 2017.
Mobile subscriber penetration globally stood at 45 per cent while mobile connection penetration is currently 94 per cent.
As per GSM Association Wireless Intelligence, the variance between the number of mobile subscribers and the number of mobile connections is related to multiple SIM ownership as well as inactive SIMs.
