The paper deals with the localization of radio emitters into collapsed buildings after earthquake. A measurement campaign has been carried out in a typical European historical city, L'Aquila, which was recently stroke by a severe earthquake. Continuous wave radio transmitters operating at 434 and 868 MHz have been introduced under rubble and their signals have been measured at different points surrounding...
The coexistence issue between ultra-wideband (UWB) radio communication systems and narrow-band wireless LAN systems is investigated by experiments and simulations. The work is divided in two parts. In this Part II, either impulse radio or multiband orthogonal frequency-division multiplex systems are assumed to be the disturbance source, while narrow-band wireless systems based on IEEE 802.11a/b are...
