In 2014, operators are feeling the pressure from several quarters. Revenues from mobile and fixed line services are continuing to decline; traditional applications such as SMS are suffering erosion from innovative IP-based rivals; and the traffic across the network footprint is growing exponentially, with customers calling for higher performance and interconnectedness of experience. By the end of 2014, Informa’s WCIS+ forecasts almost 386 million LTE connections around the world. By the start of 2020, this number will have leapt to over 2.3 billion. This means 27 per cent of the predicted 8.4 billion mobile connections will be running on 4G technologies by 2020, with the balance largely on 3G.
