Content

  • CALM Overview

  • CALM Architecture

  • CALM Standards Status


What is CALM?


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


Vehicle Architecture


CALM OSI Reference Architecture


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 - Basic Example


CALM - Complex Example


CVIS CALM M5 Architecture


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


Status of CALM Standards


CALM Standards

CD 21210: CALM networking for Internet Connectivity

CD 21212: CALM 2G medium

CD 21213: CALM 3G medium

IS 21214: CALM IR medium (already published)‏

CD 21215: CALM M5 medium (cf. IEEE 802.11 TGp)

WD 21216: CALM MM medium

CD 21217: CALM global architecture

DIS 21218: CALM lower layer service access points

CD 24101: CALM application management

CD 24102: CALM station manager

CD 29281: CALM non-IP networking (cf. IEEE 1609)

WD 29282: CALM applications using satellite

... and others


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.)
