Many developing countries are preparing for a second wave of regulatory reform designed to enable them to harness the promise of new technologies and participate fully in the information society. This report examines a range of innovative sharing strategies regulators can use to speed up the uptake of ICTs and promote widespread, affordable broadband access. This year's Trends focuses on "Six Degrees of Sharing", examining active and passive infrastructure sharing, open access to international capacity, business sharing, end-user sharing and regulatory sharing.

Spectrum sharing

This chapter reviews various spectrum-sharing methods that increasingly are being used to respond to the escalating demand for spectrum, which has been sparked by the seemingly unstoppable surge in new wireless services and technologies. Spectrum sharing encompasses several techniques – some administrative, some technical, and some market-based. Spectrum can be shared in several dimensions: time, space and geography. Limiting transmission power is also a way to permit sharing among low-power devices operating in the spectrum “commons” – as explained later with dynamic spectrum access, which takes advantage of power and interference reduction techniques. Sharing can also be accomplished through licensing and/or commercial arrangements involving spectrum leasing and trading.
