Abstract
Et utspørringssystem for innkobling av sending og/eller mottaking av RF-signaler med en kommunikasjonssystem. I henhold til foreliggende oppfinnelse foretas det en utspørring mellom en sender/mottaker og en antenne før sender/mottakeren sender eller mottar RF-signaler via antennen. Utspørringen benyttes til å bestemme om antennen sender og/eller mottar RF-signaler som har den effekt og/eller det frekvensbånd som er nødvendig for sender/mottakeren. Utspørringen foregår med en utspørringsanordning som sender et utspørringssignal til den andre svarende anordning. Den svarende anordning sender et svarsignal til den utspørrende anordning som reaksjon på mottaking av utspørringssignalet. Den utspørrende anordning bestemmer om svarsignalet har en forhåndsbestemt karakteristikk. Hvis svarsignalet har den forhåndsbestemte karakteristikk, blir sending og/eller mottaking av RF-signalene utført. En alternativ bruk av utspørringen er å identifisere hvilken av et flertall antenner som er koblet til sender/mottakeren som skal benyttes til å sende eller motta RF-signaler.
