The past decade saw the breakthrough of wireless data networks. The telecom
sector continued making progress in cellular networks, with traditional
systems strategies centred around licensed spectrum (GPRS, 3G etc.) In
parallel, the datacom industry had tremendous growth in the uptake of
networking devices based on the IEEE 802.11 standards family. These networks
are fundamentally different in that they operate in unlicensed spectrum
where traditional engineering principles are unsuitable. It has been shown
that these networks can suffer greatly in the face of contention, and the
current systems approach of constructing networks in isolation can lead to
undesirable and in some cases extremely poor performance.

In this talk, we will discuss the problems and issues around unlicensed
networks, look at how collaboration can mitigate some of these issues and
briefly present some specific results from work done at the University of
Sydney in this space.
