Much of the final day of the Mobile World Congress was spent talking about emerging markets, says Prof. Javier Zamora. We are in transition from connectivity to hyper-connectivity and we are not far off the figure of 50 billion interconnected devices. Costs continue to fall and a smartphone that now costs $400 will soon sell for $20. However, only 2 billion of the 7 billion people in the world are connected and this has created a digital divide. Meanwhile, 4G telecoms will be able to work in real time, making it possible to design smart cars and smart cities. |
