The remote network node converts the received optical transmission signal to an electrical transmission signal, and detects the DC level of the electrical transmission signal. If the detected DC level satisfies a predetermined condition, the remote network node connects the antenna port of the antenna switch, and thus the antenna, to a reception signal path of the remote network node. Otherwise, the remote network node connects the antenna port of the antenna switch, and thus the antenna, to a transmission signal path of the remote network node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Antenna switch control method for analog radio over fiber systems","description":"A central node connected to a remote network node via a fiber optic link controls an antenna switch in the remote network node by controlling the DC bias current of the laser providing an optical tran","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9647752","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.
