What is CALM?

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

Terrestrial Broadcast






  • Beacon

  • 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 stand alone example

CALM Stand-alone Example

ISO 21217

Calm basic example

CALM - Basic Example

Calm complex example

CALM - Complex Example

Cvis calm m5 architecture

CVIS CALM M5 Architecture

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

Tc204 wg16 cooperation

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

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 developments1

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.)
