In this paper we investigate the localization performance limits of massive arrays working at mm-wave frequencies and adopting two different beamforming strategies. In the first one, array weights are set in order to point towards a precise direction (classic beamforming), whereas in the second one, such weights are randomly chosen (random beamforming). Thanks to the large set of measurements as well...
Next generation cellular networks will experience the combination of femtocells, millimeter-wave (mmW) communications and massive antenna arrays. In addition to benefits in terms of an increased communication capacity, this mix of technologies can be fruitfully exploited to enable high-accuracy indoor positioning. In fact, thanks to the high beamforming capability of massive arrays, mobile terminal...
Nowadays, passive and semi-passive wireless devices are increasing their appeal, particularly in the new scenario of the Internet of Things, thanks to their low complexity and low energy consumption. In this context, radio-frequency identification (RFID) and radar sensor networks (RSNs) are rising interest when the localization of (semi-)passive tags (without active transmitters) and moving passive...
