List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 01 Dec 2014 15:05:42 -0000 Hello, ETSI ITS just published: CAM - "Specification of Cooperative Awareness Basic Service", EN 302 637-2 V1.3.2. DENM - "Specifications of Decentralized Environmental Notification Basic Service", EN 302 637-3 V1.2.2. The specs should be freely downloadable from the web, just google for them. CAM and DENM messages could be sent from one vehicle to another, over an 802.11p link called G5 (for Giga-hertz 5 band, not to be confused with 5G for Generation 5). They are not carried as IP datagrams, for various reasons. I wonder what is the minimum length of a CAM message? Alex
