Thus, in a case where there is no portable device which enables wireless communication with the control device, a value of received signal strength indication of a wireless signal which is received from the portable device by the control device is very small and becomes smaller than the threshold value during a period in the common period. In this case, the control device suspends reception processing of causing a signal to be transmitted from the plurality of portable devices subsequently to the first response signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication system, communication method, and control device","description":"If a portable device receives a request signal from a control device that requires a response from the portable device, a first response signal is transmitted from the portable device during a common ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9836902","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.
