In a key embodiment the message duration is equal to or less than a predetermined time slot duration. Embodiments use generally the same time slot in a contiguous sequence of basic time intervals. Algorithms are described to resolve wireless interference within a time slot. Embodiments divide the basic time interval in multiple durations, “class regions,” for different message classes. Embodiments use different wireless bandwidth allocation algorithms for the class regions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time-slot-based system and method of inter-vehicle communication","description":"Device, system and method, in a vehicle communication system, to transmit wirelessly a message comprising the position, heading and speed of a vehicle or other moving object, wherein the transmission ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520695","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
