Direct connectivity between vehicles will let a variety of new applications become a reality, from safety to traffic management and infotainment. Different wireless access technologies can enable this kind of connections, from mobile-fi IEEE 802.11p in the US and ETSI G5 in Europe, to the more recent 3GPP long term evolution (LTE) for vehicle-to-vehicle (V2V) communications. To integrate the capabilities...
Recent advances in the electronics for wireless communications is enabling transceivers to transmit and receive signals at the same time. Thus, the so called full duplex (FD) radios will soon be introduced in devices as opposed to traditional half duplex (HD). However, although FD radios allow to almost double the capacity of a single link, the advantage obtained in a network is still debated and...
The acquisition of environmental information from vehicles is expected to overload cellular networks. Short range vehicle-to-vehicle and vehicle-to-roadside wireless communication technologies, such as IEEE 802.11p, are being foreseen for the offloading of cellular networks. A nearer breakthrough in this direction is represented by visible light communication (VLC), which can exploit light emitting...
