doc.: IEEE / dsrc Submission September 2003 Knut Evensen, Q-FreeSlide 17 Extract from formal scope: CALM-M5 ISO :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.

doc.: IEEE / dsrc Submission September 2003 Knut Evensen, Q-FreeSlide 18 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;

doc.: IEEE / dsrc Submission September 2003 Knut Evensen, Q-FreeSlide 19 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.

doc.: IEEE / dsrc Submission September 2003 Knut Evensen, Q-FreeSlide 21 Spectrum M5 For global use, the OBUs shall: –Be capable of operating within the range of 5.15 GHz to GHz –Support both 10 and 20 MHz channels –Support accurate transmit power control RSUs will operate on the regionally allocated frequencies.

doc.: IEEE / dsrc Submission September 2003 Knut Evensen, Q-FreeSlide 22 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.

doc.: IEEE / dsrc Submission September 2003 Knut Evensen, Q-FreeSlide 23 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.

doc.: IEEE / dsrc Submission September 2003 Knut Evensen, Q-FreeSlide 24 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.
