The companies claim OpenRoaming offers the ability to unlock solutions to the large data transfer challenge for fully connected autonomous vehicle fleets.
Autonomous vehicle software specialist Oxbotica and Cisco have joined forces in a bid to leverage the high volumes of data produced by fully connected autonomous vehicle (AV) fleets on the move.
According to Oxbotica, the partnership marks an important operational milestone for the company as it prepares for large-scale deployment of its autonomy software.
AVs make 150 independent vehicle detections every second and generate up to 80 gigabytes (GB) of data per driving hour from sensors such as LiDAR, cameras and radar as well as advanced driver assistance systems (ADAS) logs.
This constant activity means amassing 1.2 terabytes (TB) of data in a 16-hour day – much of which is gathered when the vehicle returns to base.
By 2024, it is forecast that more than 70 million new connected vehicles will enter the market every year, with each required to upload and download 8.3GB of data per day,
This will include a mix of streamed infotainment, HD navigation, vehicle telemetry and ADAS settings – as well as safety-critical information like severe weather updates or passenger ill-health. By comparison, the average smartphone will contribute a fifth of this daily volume.
“Fleets will need to upload and download vast amounts of data and the partnership with Cisco offers us the chance to solve one of the greatest data challenges of the future.”
Stretched across an autonomous fleet, which could include hundreds or even thousands of vehicles in a city or region, this would produce an abundance of data beyond that which could be shared efficiently and cost-effectively using existing 4G or emerging 5G networks.
Oxbotica has started work on addressing this challenge via OpenRoaming, a Cisco-initiated federation of providers utilising standards-based wireless technology.
The partners claim OpenRoaming offers the ability to unlock solutions to the large data transfer challenge for autonomous vehicle fleets. On-road trials have already taken place in Stratford, East London last September.
The technology enables devices, whether it be smartphones or AVs, to automatically connect to trusted Wi-Fi hotspots and networks without the need to enter usernames and passwords, instead using embedded credentials issued by identity providers – in this case, OEMs or AV software companies.
“Today’s autonomous vehicles generate enormous amounts of data when they operate. The challenge is how to gather that information from the vehicle automatically and, perhaps more importantly, cost-effectively.”
OpenRoaming is said to be particularly suited for connected vehicles, with opportunities for Wi-Fi hotspots to be deployed in locations such as petrol stations, EV charging locations, parking structures and vehicle service centres.
“As part of our universal autonomy vision, our pioneering software already reduces the amount of data-sharing that is required, allowing vehicles to operate wherever they are, with or without network connection,” said Ozgur Tohumcu, CEO at Oxbotica.
“However, we fully recognise that in an autonomous world, fleets will need to upload and download vast amounts of data and the partnership with Cisco offers us the chance to solve one of the greatest data challenges of the future, already today.”
The Next Generation Connected Vehicles Co-innovation” trial collaboration with Cisco sets out to demonstrate how Oxbotica customers will be able to access, customise and integrate its mobile autonomy IP into their own products.
The platform to be tested is designed to be fully scalable and capable of being deployed across various fleet networks no matter the size or location, while delivering cost-effective and secure data offload.
“Today’s autonomous vehicles generate enormous amounts of data when they operate. The challenge is how to gather that information from the vehicle automatically and, perhaps more importantly, cost-effectively,” added Matt MacPherson, wireless CTO at Cisco.
“Tomorrow’s connected cars will face the same issue. OpenRoaming opens up the possibility of a cost-effective alternative for transporting high-volume data to and from the vehicle, autonomously.”
