2What is CALM?
3CALM - Overall
- Continuous Air interface for Long and Medium
distance - ISO TC204/WG16 Wide Area Communications
- Support 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
4CALM Communication Scenarios
5CALM Applications
- Support of Internet services
- Support of traditional ITS apps media
independent through DSRC L7 - New generation of applications
- Major push in safety Vehicle Safety
Communication - New commercial applications made possible by high
data rate long range.
6TC204/WG16 Co-operation
- IEEE 802.11p and P1609 Wireless Access in
Vehicular Environments (WAVE)- Co-operation
agreement with WG16 - ETSI ERM TG37 2G/3G standards, spectrum and
test standards, - IETF Internet Network Mobility (NEMO)
- ITU-R WP 8A Global radio standards
- USA projects VSCC and VII
- Japan projects CALM Proof-Of-Concept,
- European projects C2C-CC, CVIS, SafeSpot,

13Communication Scenarios
- CALM defines 5 communication scenarios
- 0 V2I Non-IPv6 (WSMP or C2C-CC?)
- 1 V2I/V2V Local IPv6
- 2 V2I MIPv6
- 3 V2I NEMO
- 4 V2V Non-IPv6
- (WSMP or C2C-CC?)
14What is CALM M5?
15US DSRC (WAVE)
- WAVE is IEEE 802.11p Wireless Access for
Vehicles - as required by US DoT/VSCC/VII/ - WAVE is optimised for US channel plan
- WAVE protocols are optimised for current
single-radio technology. - No GSM or other technology is included.
16CALM M5
- CALM M5 incorporate WAVE and adds
- Global (European) 5 GHz spectrum
- Regulatory domain (border) management
- Directivity and EMC control
- CEN DSRC co-operation
- Multiple radio/interface/antenna management
- GPRS/UMTS network interconnectivity

18ETSI ERM TG37
- Process of European frequency selection is
underway. - System Reference Document (SRD) split in three
parts - pan-European allocation with at least 210MHz
bandwidth - National allocations with at least 410MHz
- Mobile use of current unlicensed bands 5.4-5.6
GHz - Request for frequencies in 4.9-6.0 GHz band, but
most likely in the 5.9 GHz band. Potential
interference with 5.8GHz DSRC must be solved by
system integration - Power level is dynamic from 0dBm 33dBm EIRP
- Process involves several steps with ETSI CEPT
and national authorities. Possible first ideas
early 2006.

20Draft Status
- Architecture has been out for commenting
- Comments will be resolved next meeting
- Major draft overhaul expected.
- Expect ballot late 2005
- M5 is depending on results from 11p
- Mostly dormant until stable results arrive.
- Will add functions from LL-SAP and Interface
Manager
