By 2020, connected devices will outnumber connected people by six to one, and mobile broadband will be driving internet usage as fixed connections dwindle, according to a new report.

Worldwide, the number of mobile broadband users already outnumbers fixed broadband users by a ratio of two to one, and that imbalance will only grow over time as more developing country users upgrade their mobile phones to smartphones and tablets.

New concepts such as embedded intelligence, automated machine-to-machine (M2M) traffic, and the ‘Internet of Things’ are also contributing to the growth in networked devices, and the demand for seamless wireless connectivity has never been greater.
