Experimental evaluation on UWB aggregation and coexistence

A measurement campaign has been carried out in Japan to evaluate UWB technology for both aggregation characteristics and coexistence performance. Different from other previous studies, our evaluation is based on measurements with real devices. We examined both UWB low band and UWB high band, the latter has rarely been investigated by others. UWB aggregation results with real measurements are also rare. Both OFDM type and impulse type UWB were used in the measurements. Coexistence evaluations with several existing wireless systems were conducted. Main results of the measurements and evaluations are presented.
