What is CALM?
4
CALM - Overall

• Communications Access for Land
  Mobiles
• 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

• Beacon
• CALM-M5
• CEN-DSRC
• CALM-IR

Hot-Spot (Wireless LAN)

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!

7
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 156282007.
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)

• 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

  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

21
Recent Standards Developments
