Researchers at Warwick University have set what they believe to be a new 5G communications vehicle-to-infrastructure speed record.
Warwick Manufacturing Group, WMG, says its tests included sending messages to a low-speed autonomous vehicle and that the messages were sent in the 28 GHz millimetre wave band and reached speeds of of 2.867 gigabits a second.
WMG explains that this is “nearly 40 times faster than current fixed line broadband speeds”.
The researchers explain that this is equivalent to sending a detailed satellite navigation map of the UK within a single second, or the full contents of a high definition blockbuster film in less than 10 seconds.
The researchers say they optimised antenna placement both inside the pod, and on roadside infrastructure, such as a traffic light.
Dr Matthew Higgins, associate professor, explained, “These controlled trials are critical to better understand the capabilities of 5G in millimetre wave bands, and how infrastructure providers and vehicle manufacturers must carefully plan and deploy their 5G service and application rollout over the next few years.
“This project, which includes real-world 5G mmWave trials on the University of Warwick’s campus, will also attempt to examine how the dynamics of both the vehicle and the environment affect performance between infrastructure and connected and autonomous vehicles.”
Bob Slorach, CTO of the UK-based Wireless Infrastructure Group, which provides support to the project, added, “This is an exciting step towards to the realisation and deployment of future 5G applications, like connected and autonomous vehicles, which will be enabled by fibre connected wireless infrastructure that supports high data rates and ultra-low latency mobile broadband.”
In this instance, a driverless pod from the company Aurrigo was used. This vehicle is a level 4 autonomous vehicle.
