  • CALM Overview
  • CALM Architecture
  • CALM Standards Status
calm overall
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
CALM – an overview

GPS, Galileo

  • CALM-M5


(Wireless LAN)



PDA access

Vehicle-to-Vehicle (M5, IR, MM)


why do we need calm
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
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 m5 radio s
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
