Management of UWB picocell clusters: UCELLS project approach

In this paper the UWB cellular architecture proposed in the IST-UCELLS project is described. This architecture targets to provide Gb/s indoor connectivity employing very low-cost UWB transceivers. The picocell clustering of UWB transmitter overcomes the severe range limitation of stand-alone UWB technology. A photonic analog-to-digital converter (Ph-ADC) is developed in UCELLS for localization, fingerprinting and spectral management of UWB transceivers. This approach minimizes interferences and optimizes the user capacity in the picocell cluster area.
