Predictor Antenna: A Technique to Boost the Performance of Internet-of-Vehicles Networks

#Internet-of-vehicles #(IoV),wireless #antennas #satellite.

 One of the use-cases of interest in future wireless networks is Internet-of-vehicles (IoV). Here, IoV refers to two different functionalities, namely, serving the in-vehicle users and supporting the connected-vehicle functionalities, where both can be well provided by the transceivers installed on top of the vehicles. Such dual functionality of the on-vehicle transceivers, however, implies strict rate and reliability requirements, for which one may need to utilize large bandwidths/beamforming, acquire updated channel state information and avoid blockages. In this webinar, we present the recently proposed concept of predictor antennas (PAs) as an efficient technique to improve the performance of such IoV links. Particularly, we introduce the concept and the potentials/challenges of PA systems. Moreover, summarizing the initial field trials for PA systems and the 3GPP attempts on (moving) relays, we compare the performance of different PA and non-PA methods for vehicle communications in both urban and rural areas with the PA setup backhauled through terrestrial or satellite technology, respectively. As we show, a dedicated PA deployment has the potential to improve the performance of IoV networks.
