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.Mobi 1 radio system with a central and with base stations, where the base stations (FSi to FS) send and receive radio signals to and from mobile subscribers (MS). According to the present invention, the radio igniters are not generated or processed as usual in the base stations, but in the control panel (1). The control panel (1) also contains a microwave transmitter / receiver (SE i to SE) for each base station (F S i to FS), and this transmitter / receiver converts the signals to be sent to the base station into radio signals and the signals received from the base stations to the baseband. This gives the advantage that the carrier device can be common to many base stations, so that the cost of the system is reduced.
