STATUS OF CALM IEEE 1609 Meeting – Los Angeles29 April – 1 May 2008 dickroy@alum.mit.edu
Content • CALM Overview • CALM Architecture • CALM Standards Status
CALM - Overall CommunicationsAccess forLandMobiles • Provide user transparent continuous communications • CALM is the first open way to combine GPRS with vehicle-optimized WLAN technology. - NOT a complicated collection of new, unproven radio technologies
CALM – an overview GPS, Galileo Terrestrial Broadcast RDS, DAB Sat-Comm GSM-GPRS UMTS WiMAX • Beacon • CALM-M5 • CEN-DSRC • CALM-IR Hot-Spot (Wireless LAN) Roadsign broadcast PDA access Vehicle-to-Vehicle (M5, IR, MM) Info-Broadcaster
Why do we need CALM? • ITS is cooperative and safety sensitive • Many actors spanning from authorities, via manufacturers to end users • Applications and services interact they share data and functions • Technology must be interoperable across borders • Public safety services requires proven performance level • All interfaces must be fully open – no competing proprietary solutions • Test specifications required for guaranteed interoperability and performance • Formal standardization is needed!
CALM Applications • Support of Internet services • Support of traditional ITS apps • Traffic info, Road Tolling, Route Guidance,… • New generation of applications: • Major push in Vehicle Safety Communication (C2C-CC/SAFESPOT) • New commercial applications made possible by high data rate & long range. • 300+ applications defined so far
CALM Architecture Details CALM-aware applications, and CALM non-aware applications being based on ISO 15628:2007. Integrated CALM FAST networking and transport layer protocol. Integrated CALM geo-routing and transport layer protocol. Optional FAST local port transport protocol. ISO 21217 Multiple wireless and wired CIs. One global CALM management with functionality of IME, NME, CME.
CALM Stand-alone Example ISO 21217
CALM M5 Radio(s) • Two miniPCI “European” Atheros radios • Modified version compared to (most) US tests • Additionally includes: • Synchronization to European DSRC Toll Collection systems according to ETSI requirements • European 5.9GHz spectrum plus 802.11abg • GPS time-slot sync for performance optimization • Full P1609.4 stack (US operation compatible) • Full CALM management for parallel stacks • Open access to APIs and SAPs, both native code LINUX and OSGi/GST based portable services

TC204/WG16 Cooperation • IEEE 802.11p and P1609 – Wireless Access in the Vehicular Environment (WAVE)- Cooperative agreement with WG16 • ETSI TC ITS – new actor for 2G/3G standards, European spectrum and test standards,… • IETF – Internet - IPv6 - Network Mobility (NEMO/MONAMI -> MEXT) • USA projects: VSCC and VII • Japan projects: CALM Proof-Of-Concept,… • Europe projects: C2C-CC, CVIS, SafeSpot,…
Recent Standards Developments • ETSI TC ITS – new technical committee for ITS-related 2G/3G standards, European spectrum allocations, test standards,… • ISO TC204 WG17 – new working group developing standards for the use of nomadic and mobile wireless devices (eg., Bluetooth) to support ITS service and multimedia provision in vehicles
Recent Standards Developments • ISO/IEEE Partner Standards Development Organization (PSDO) cooperation agreement recently signed • TC 204 ITS specifically called out • Joint standards development procedures are specified (cf. Section 5.2 ff.)
