The EU (European Union) is taking a welcome coordinated approach to establishment of cross-border transport corridors for safety and automation, particularly for roads. Having originally favored WiFi over cellular for communications between vehicles and roadside infrastructure for projects leading towards autonomous driving, the EU has swung towards 5G for various reasons, chiefly that low latency requirements are closer to being met and there is support for longer range non line of sight communication. Deployment will involve optical/Ethernet backhaul structures along the transport links, with small cells then connecting at relatively short range to antennas on top of the vehicles or trains (see separate item). Europe of all regions has the greatest need for reliable cross-border mobile communications for transport with…
