  2. What is DSRC? • Dedicated Short Range Communication • Dedicated = Developed for ITS • Short-Range = 1 – 40 meters, typ 8-10 m • 2W EIRP ASK downlink (roadside – vehicle) • 50mW DPSK reflected uplink (veh – roadside) • Passive mixing reflector – no RF generated in vehicle Knut Evensen, Q-Free

  3. ETC Application (ISO14906) Data/Attributes ETC functions Selection of parameters Inter-layer management DSRC Profiles (EN13372) DSRC Application Layer 7 (EN12834) Initialisation Data Transfer DSRC Data Link Layer 2 (EN12795) Logical Link Control Medium Access Control Frequency Spectrum Interference levels Modulation ++ DSRC Physical Layer 1 (EN12253) Knut Evensen, Q-Free

  4. ETSI ERM TG37 • A new Topic Group dedicated to ITS communication • Very good relation to CALM • Chairman is Bob Williams • TG37 will look at: • Spectrum matters 5-6 GHz for Europe • Cellular convergence standards • Testing and formal protocol verification • Please see www.etsi.org ERM forum – TG37 Knut Evensen, Q-Free

  6. CALM - Overall • Continuous Air interface for Long and Medium distance • Support continuous communications • Support master/slave and peer-peer modes • Support user transparent networking • Support handover spanning multiple media, media providers and beacons • Very ambitious timescale – ISO test-case for fast development Knut Evensen, Q-Free

  7. CALM Applications • Support of Internet services – invisible handover –(mostly) media independent • 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. Knut Evensen, Q-Free

  8. CALM -IETF • A very good liaison to the Internet Engineering Task Force has been set up • Main support from experts at Keio university T. ERNST /K. UEHARA • CALM concept is forwarded to IETF to make various groups aware of mobility requirements • IETF NEMO (Network Mobility) group is closely following CALM. Will be the contact point to IETF Knut Evensen, Q-Free

  20. Extract ISO-approved M5 scope: • CALM-M5 ISO 21215 :Medium and long range, high speed, air interface parameters and protocols for broadcast, point-point, vehicle-vehicle, and vehicle-point communications in the ITS Sector using MICROWAVE COMMUNICATIONS at 5 GHz, including specifications for Master/Slave and Peer to Peer Communications. • The work item will specify the required communication architecture, interfaces, parameters and protocols for the • Physical Layer • Data Link Layer: Medium Access Control (MAC) and Logical Link Control (LLC) • Wherever practicable, this Standard will be developed by reference to suitable extant Standards, adopted by selection. Required regional variations will be provided. • Due account will be given to, and use made of, any relevant parts of appropriate communications systems, such as Global Positioning Systems (GPS), Digital Audio Broadcasting (DAB), Digital Video Broadcasting (DVB), Digital Data Broadcasting (DDB), TETRA, Mobile Broadband Systems (MBS, W-ATM), WLANs, Internet Protocols, and of course, DSRC. Knut Evensen, Q-Free

  21. Scope of CALM M5 • The standard: • shall use microwaves in the 5 GHz band as the transmission medium between (moving or stationary) vehicles and a roadside communications-infrastructure or other (moving or stationary) vehicles; • shall minimise harmful interference with standardised regional radio unit in this spectrum, e.g. no harmful cross-interference with regional DSRC standards; Knut Evensen, Q-Free

  22. Scope of CALM M5 • The Standard: • shall support vehicle speeds to a minimum of 200km/h; • shall define or reference environmental parameters relevant to link operation; • shall support latencies and communication delays in the order of milliseconds; • shall be adaptable to regional/national regulatory parameters; • may support other regional/national parameters as applicable. Knut Evensen, Q-Free

  23. 5 GHz Band Spectrum Europe Japan North Ameri ISM band CALM M5 Unlicen. W-LAN Partly available regionally: ISM + shared unlicenced Requested from ITU: Global ITS Safety allocation 5.85-5.925 Dedicated ITS (DSRC) Knut Evensen, Q-Free

  24. Spectrum M5 • For global use, the OBUs shall: • Be capable of operating within the range of 5.15 GHz to 5.925 GHz • Support both 10 and 20 MHz channels • Support accurate transmit power control • RSUs will operate on the regionally allocated frequencies. Knut Evensen, Q-Free

  25. Global M5 spectrum config. • The mobile unit (OBU) shall be configurable when moving between regulatory areas • The OBU shall not start operation until an authorised source (e.g. fixed, licensed RSU) has provided profile information. • Profiles may be autonomously initiated if the OBU can ascertain its position. Knut Evensen, Q-Free

  26. M5 Access Methods • National regulatory bodies can place limitations on channel utilisation and maximum channel usage on a per channel basis, and the unit shall be configurable / programmable to operate within these limitations. Knut Evensen, Q-Free

  27. M5 Directivity • CALM M5 include omni-directional as well as directive patterns. • The standard allow control of multi-sector directed antenna elements. • The standard allow simultaneous operation on multiple channels in the same or different directions. Knut Evensen, Q-Free

  28. Conclusion • CALM M5 - likely candidate for the next high-volume ITS communication medium • The public safety applications requires global spectrum allocations. A liaison (formal?) to IEEE 802.11! Knut Evensen, Q-Free
