The pico cell system operates one type of service on all or a portion of a band used for a different type of service by the public system. In the aircraft example, a pico cell system might support GSM narrowband service and CDMA broadband service. The airborne GSM operations use a portion, e.g. corresponding to a guard band, of CDMA service spectrum in the terrestrial network. The airborne CDMA service uses a band used for GSM service by the terrestrial network. The pico cell system dynamically changes its frequency band(s), as the aircraft flies over different areas."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency overlay technique for a PICO cell system","description":"To ameliorate interference between an indoor wireless pico cell system, for example in an aircraft, and public wireless communications systems operating in a surrounding or over-flown area, frequencie","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526379","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.
