This issue of Philosophical Transactions of the Royal Society, Part A represents
a summary of the recent discussion meeting 'Communication networks beyond the
capacity crunch'. The purpose of the meeting was to establish the nature of the
capacity crunch, estimate the time scales associated with it and to begin to find
solutions to enable continued growth in a post-crunch era. The meeting confirmed
that, in addition to a capacity shortage within a single optical fibre, many
other 'crunches' are foreseen in the field of communications, both societal and
technical. Technical crunches identified included the nonlinear Shannon limit,
wireless spectrum, distribution of 5G signals (front haul and back haul), while
societal influences included net neutrality, creative content generation and
distribution and latency, and finally energy and cost. The meeting concluded with
the observation that these many crunches are genuine and may influence our future
use of technology, but encouragingly noted that research and business practice
are already moving to alleviate many of the negative consequences.
