The telecommunications device also includes a network interface to communicate via a data network using the network address and a processor to establish a communication session with another device over the data network based upon receipt of a response from the other device via the data network, the response including at least the random number code. The telecommunications device does not establish the communication session with the other device if the random number code is missing from the response or if the random number code in the response does not match the random number code transmitted in the ultrasonic sound waves."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and associated methodology for detecting same-room presence using ultrasound as an out-of-band channel","description":"A telecommunications device includes an electronic memory to store at least a network address and a random number code, and a sound unit to transmit the network address and the random number code via ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11303362","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.
