The PD determines a preferred PoE voltage among the multiple candidate PoE voltages that minimizes a total power loss due to (i) the cable, and (ii) a power loss of the PD that would result if the PD were powered through the cable. The PD requests the preferred PoE voltage from the PSE, receives the preferred PoE voltage from the PSE, and operates at the preferred PoE voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Negotiable PoE voltage for improved efficiency based on cable and powered device losses","description":"A powered device (PD) receives a Power-over-Ethernet (PoE) voltage to power the PD over a cable from Power Source Equipment (PSE) configured to output a requested one of multiple candidate PoE voltage","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9847884","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.
