The control unit comprises a generating component for generating a band-limited masking signal for masking terrestrial mobile communications signals in a first frequency band and a combining component for combining the band-limited masking signal and a service signal for the wireless transmission of data in a second frequency band different from the first frequency band. The combining component is configured to combine the masking signal and the service signal so that terrestrial mobile communications signals in a third frequency band formed by overlapping of the first and the second frequency band are masked."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Service signal used as part of terrestrial communications masking signal on board aircraft","description":"A control unit for controlling wireless data transmissions in a mobile communications system provided on board an aircraft, a mobile communications system having a control unit of this type, an associ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9831981","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.
