Wireless communications are experiencing an unprecedented expansion. The
increasing mobility of the communication society and the pace of
technological change are growing pressure for more spectrum to support
more users, more uses and more capacity. Thus, spectrum management has
become an extremely important part of wireless communications. A few
regulators are changing their traditional ‘command and control’ approach.
Nevertheless, many features of optimal spectrum management are still
widely discussed. This work is aimed at contributing to that discussion.
The key insight is that spectrum management can benefit from more
liberal spectrum sharing. This work set out to answer three main research
questions: (i) whether there is a theoretical framework which can be used to
analyze and guide spectrum policy reform, when moving from a traditional
‘command and control’ regime to a market-inspired one; (ii) whether it is
possible to design a plausible mechanism which can promote efficient
allocation and assignment of spectrum commons; (iii) whether (and how)
technological developments could enable band sharing methods outside the
traditional management framework and without harmful interference.
The literature on transition economics and policy was used to help
answer the first research question. Evidence from liberalizing countries was
positively analyzed to discuss reforms of spectrum allocation and
assignment methods. Most countries have adopted strategies that gradually
change their spectrum policies and started by using more liberal methods to
assign spectrum. It is also argued that future spectrum reforms might benefit
from insights presented in the transition economics literature.
A translation of a model on cartel quotas under majority rule is
proposed to answer the second research question. The work verifies, firstly,
that an analogous set of properties is satisfied under our assumptions and
that the median-index theorem applies, mutatis mutandis, to our setting.
Thus firms bidding to acquire spectrum commons contribute a minimum
amount of their wealth; the sum of contributions offered is then compared to
other bids for the same spectrum, which is allocated to the highest bidder.
The last research question considers novel ways of spectrum sharing
that might be enabled by technological developments. The work explores
contributions, from various research areas, regarding management of scarce
resources. Those contributions are discussed with respect to shared spectrum
access. It is suggested that spectrum management might benefit from
methods which enable the management of pooled (intermittent) demands for
access, especially methods in line with fair sojourn protocols.
