The embodiments further disclose a scanning system in a WLAN. By using the method and system, not only the time delay during the scanning is reduced, but also the network security is improved and the difficulty for realization is decreased."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for scanning in WLAN","description":"The embodiments disclose a method for scanning in a radio communication system, in particular in a WLAN (Wireless Local Area Network), including transmitting by a MS on all channels a probe message co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8503390","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.
