Green Wireless Internet Technology

In the future, communications will be pervasive in nature allowing users to access at the 'touch of button' any service, at any time, on any device. This will require future devices to go beyond the rigid specification we have today, to be reconfigurable in nature in order dialogue with a whole host wireless networking, even including the eventual 5G communication portal. In fact, an energy trap is starting to emerge where users could be bound to the nearest available power sockets instead of enjoying the full benefits of user mobility, that 5G and beyond is likely to offer. On the hand, the energy bill accounts for the largest operational expense for mobile operators, which is likely to proliferate. Overall, the papers presented here represent a cross-section of leading-edge work across a range of topics relevant to the theme of the Special Issue, drawn from a broad spread of international contributors and giving clear indicators of the way in which work to address the green communications agenda is progressing.
