Tests and demonstration in Berlin
December 2008
Road site Equipment
DLR operates appr. 1.2 km of an Urban Road Research Laboratory (Test
Track) with sensors, two gantries and high data rate access via control
cabinets
Control cabinets with air condition,
power supply, data lines and free
space for further equipment
DLR owned gantries with any time
access for mounting sensors

Demonstration Vehicles
CVIS rented two transporters with 8 seats for the M5 demonstrations.
Installation effort: 2 hours per car

• The reference
execution platform in
CVIS consisting of a
CVIS host and a CVIS
router.
• The Router platform is
controlling the 3G and
M5 communication
modules.
• The Host platform hosts
the CVIS middleware
and service provisioning
application.

Service Provisioning
• Automatic service

• Triggered by CALM
M5 communication.
• Different provisioning

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
– When using the 5.4GHz WLAN band for high-capacity file transfer, 3050% extra nominal reduction due to legal power limitations
• More Access Routers may be used to extend range of RSU

CVIS Core Software
•
The CVIS Core Software toolkit offers
– vehicle-to-vehicle and vehicle-to-infrastructure
communication protocol stack
– channel-switching (3G, 802.11p, IR)
– software provisioning and service announcement
– life cycle management of services and
applications
– software freely available for other projects and
users under the CVIS license agreement
– quick and easy application creation
