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.

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.

23. doc.: IEEE 802.11-03/0742-00-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.
