There are generally several ways to share spectrum and achieve the goal of improving access to spectrum by giving more users greater flexibility in its use by implementing:
- Liberalized methods for assigning spectrum rights such as leasing, trading (see section 1.5.2 Market methods) and the spectrum commons (see section 1.5.3 Unlicensed spectrum);
- A new paradigm for interference protection taking into account new technologies such as dynamic spectrum access where underlay technologies are used based on power limits, for example UWB, mesh networks, software defined radio (SDR), smart antennae and cognitive radios (see section 4.2.5 Technically-enabled sharing).
The ITU conducted a New Initiatives workshop on the subject of "Radio Spectrum Management for a Converging World". The workshop was held at ITU Headquarters, Geneva from 16 to 18 February 2004. Presentations and papers from the workshop can be obtained by going to the ITU website. Go to www.itu.int/osg/spu/ni/spectrum.
