Executive Brief
Ultra Wide Band is a wireless technology developed to transmit large amounts of data over very short distances, typically less than 15 metres. With bandwidths of more than 500 MHz, the capacity of UWB devices greatly exceeds that of conventional radio transmitters.
1. Introduction
This paper discusses appropriate technical standards and possible spectrum allocation options for UWB in New Zealand. It considers a range of issues for industry and other stakeholders to comment on.
2. General Characteristics of Ultra Wide Band Technology
Ultra wide band is a wireless technology developed to transfer data at high rates over very short distances at very low-power densities. Although often considered a recent breakthrough in broadband wireless technology, the concept of UWB dates back many decades.
3. UWB Applications
UWB is being used to develop several new wireless applications, including consumer communication devices, imaging services and vehicular radar.
4. Overseas Regulatory Developments
A number of initiatives are being undertaken worldwide to develop standards and regulations for the introduction and use of UWB devices. However, the development of an international regulatory framework has been slow, owing to concerns about their impact on existing services. At present, the US is the only market where UWB devices are allowed to be operated without a licence.
6. Interim New Zealand Strategy
In the interim, to enable New Zealand companies to take advantage of the benefits offered by UWB, the Ministry is considering to grant interim radio licences for UWB applications with low potential to cause interference on a case-by-case basis.
