Ubiquitous devices are expected to be constantly connected. Utility smart meters are an example of ubiquitous computing, replacing manual meter-readers with devices that can report usage and modify power settings on ubiquitous appliances. High-bandwidth, wired, and wireless communications are now ubiquitous in most markets. Traffic from wireless and mobile devices will be 54 percent of all traffic, exceeding traffic from wired devices by 2016. By 2018, global fixed broadband speeds will reach an average of 42 Mbps, up from 16 Mbps in 2013.
