Because operating channels of two vehicle-mounted APs are different, interference between vehicle-mounted APs on one vehicle and a next vehicle is low. Moreover, a trackside AP behind a previous vehicle is instructed to change a channel such that a vehicle-mounted AP does not need to change a channel. Therefore, a handover time is short."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel management method and device for wireless local area network in rail transport, and wireless local area network system in rail transport","description":"A channel management method and device for a wireless local area network (WLAN) in rail transport, where the method includes instructing, by the controller, a to-be-changed trackside access point (AP)","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10531468","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.
