Some definitions
• ITS Station concept is defined by ETSI TC ITS and consist of:– one or more Routers (term under discussion)
– one or more Hosts (term under discussion)
– zero or more Gateways,
– and an internal network to connect these as needed
• Networks used by ITS belong to two domains:– ITS Domain consist of:
• ITS Ad Hoc, e.g. 5.9 GHz /multi-hopping network
• ITS Access, e.g. 5.5 GHz IPv6 access network
– Generic Domain consist of:• Private Access, e.g. fibre network in roadside
• Public Access, e.g. UMTS
• Core network, e.g. the global Internet

Conclusion
• Communication architectures have been a long
international standardisation task.
– Contributions from IEEE and ISO have been essential
• ITS Station concept is important
– Allows implementations ranging from single OBU to highly
complex roadside systems inside the station domain
• We need to be careful to avoid fragmentation of
Standards and reference implementations
– Would delay deployment many years
– Eventually lead to mandated systems (sub-optimal?)

• CVIS CALM media: M5 (5.9/5.5 GHz), IR and 3G (UMTS)
• SAFESPOT uses CALM M5 only (5.9 GHz )
• Common trials based on joint Control Channel (CCH)
• Two 5GHz radios enable concurrent traffic

Next stage
• Revision of Router components– Optimize reliability, ease of installation and cost
• CVIS platform extended to support:– preDRIVE/C2C communications
– GeoRoute functions
– ETSI specifications
– Will likely happen in eCoMove project
• This would give future-proof interoperability for CVIS-equipped test sites / FOT sites

Standards overview
• Standardisation status
– Basic set of CALM ISO standards approved and validated in
CVIS. IEEE 802.11p (CALM M5 base) is finally ready as well
– Facilities and application standardisation is started
– Coordination plans between CEN and ETSI has been agreed
– Coordination between DG INFSO and US DoT is ongoing
• New standardisation mandate from EC has created a lot of interest, and is a clear tool to fix challenges.
• EU-US R&D and Standards policy statement signed –CVIS involved in task force.

CEN TC278
• The TC has mainly two active WGs
– WG1 EFC: ~10 new standards
– WG12 AV/AEI: New series of EVI
• New WG on cooperative issues established at
last meeting lead by Dr. Schade (Siemens) also
in CVIS Steering committee. Scope is to study
standardisation needs for cooperative systems
• CVIS was actively represented in 2 TC
meetings last year, plus some WG meetings
Berlin 26 May 2010 CEN ETSI Workshop 28
ETSI TC ITS
• ETSI had its first active working year
• Many new WI have been established – partly
overlapping with ISO/CALM and IEEE
• Focus on safety systems, at least initially
• Request for more than 10 STFs are being
processed now
• Several experts from CVIS are involved, and
WG1+WG2 are lead by CVIS partners.
– 5 meetings last year
Berlin 26 May 2010 CEN ETSI Workshop 29
ISO TC204
• ISO TC204 is closely related to CEN TC278
• A new WG17 on nomadic systems including vehicle gateway has been established
• WG16 CALM has finalised all core standards, some extensions like CALM WAVE underway.
• ETSI specialist task force has provided formal test specs for CALM according to ISO/ETSI agreement
• CVIS partners are active - 4 meetings with 3-4 people in each meeting
Berlin 26 May 2010 CEN ETSI Workshop 30
IEEE
• 802.11p finally accepted at expert level,
only high level vote remains
• Expectation is finalised standards end
2010, rolled into full 802.11 in 2011
• IEEE P1609 is upgrading from testing
standard to full standard for 5.9GHz
protocols, same time frame.
