This report, prepared for Ofcom in collaboration with Mason Communications, assesses the value to the United Kingdom of allowing the use of ultrawideband (UWB) technology for the provision of personal area network services. As part of this analysis, we have used a hedonic pricing model to establish the likely willingness to pay for UWB services. The full report is available for downloading here. Conference presentations setting out the methodology and summarising the main results can be found here and here.
