CVIS: First results from tests and validation
Peter Christ
ETSI ITS Workshop 5 February 2009
Project objective
Increase efficiency and safety through V2V and V2Icooperation enabled by:
– an open architecture and an universal platform prototype– a wireless network amongst vehicles & infrastructure – a framework for application management
2
– a framework for application management– enhanced positioning and mapping solutions– cooperative data management and sharing– innovative cooperative applications

of applications and services
Tests and demonstration in BerlinDecember 2008
DLR operates appr. 1.2 km of an Urban Road Research Laboratory (Test Track) with sensors, two gantries and high data rat e access via control cabinets
Road site Equipment

controlling the 3G and M5 communication modules.
• The Host platform hosts the CVIS middleware and service provisioning application.
Service Provisioning
• Automatic service application provisioning
• Triggered by CALM M5 communication.

Measured results for 5,9 GHz antenna
Comparison of measured and simulated impedance match
CVIS Platform Performance M5/802.11p
• Ranges:– V2V with omni-antenna on 5.9GHz: up to 400 meters– R2V with omni-antenna on 5.9GHz: up to 400 meters – R2V with directional antenna on 5.9 GHz: up to 600 meters
• Caveats:– 5.9GHz has a line-of-sight limitation, i.e. communication will NOT work
around corners unless stations are very near each other (<20meters)– The values above are best cases. 30-50% less performance nominal– The values above are best cases. 30-50% less performance nominal– When using the 5.4GHz WLAN band for high-capacity file transfer, 30-
50% extra nominal reduction due to legal power limitations• More Access Routers may be used to extend range of RSU
