The method comprises determining whether there is any interfering signal from any other communication system transmitting at a frequency in vicinity of frequencies of frequency bands of which the multi-band cellular communication apparatus is supposed to establish contact with a base station in at least one of the frequencies within the frequency bands. If the determination gives a result of no interfering signal, a first scan procedure is applied comprising plain scanning of the frequencies of the frequency bands of which the multi-band cellular communication apparatus is supposed to establish contact with a base station in at least one of the frequencies within the frequency bands, or if the determination gives a result of an interfering signal, a second scan procedure is applied, taking into account the determined interfering signal. A frequency scanning apparatus for initial scanning, and a radio access circuitry for such initial scanning is also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for initial scanning of frequencies, frequency scanning controller, and apparatus","description":"A method for initial scanning of frequencies at start-up of a multi-band cellular communication apparatus is disclosed.
