Abstract
Mobi 1 radiosystem med en sentral og med basestasjoner, hvor basestasjonene (FSi til FS) sender og mottar radiosignaler til og fra mobile abonnenter (MS). Radios ignalene blir i henhold til foreliggende oppfinnelse ikke som vanlig generert, henholdsvis bearbeidet, i basestasjonene, men i sentralen (1).Sentralen (1) inneholder også en mikrobølgesender/-mottager (SE i til SE) for hver basestasjon (F S i til FS), og denne sender/mottager omformer signalene som skal sendes til basestasjonen til radiosignaler og signalene som mottas fra basestasjonene til basisbåndet.Dette gir den fordel at bærebølge-innretningen kan være felles for mange basestasjoner, slik at kostnadene til systemet reduseres.
