Wireless communications equipment

A FWA system constituting an indoor unit and outdoor unit connected via a coaxial cable and provided with a communications unit that communicates signals on a plurality of communication frequencies, wherein:

• the indoor unit constituting the communications unit comprises:
• baseband frequency-side frequency conversion means that performs conversion between baseband signals on the baseband frequency and signals on a stipulated frequency higher than the baseband frequency and different from the intermediate frequency, intermediate frequency-side frequency conversion means that performs conversion between the signals on said stipulated frequency and intermediate frequency signals on a plurality of intermediate frequencies corresponding to a plurality of communication frequencies, and unwanted frequency signal component removal means that removes signal components of unwanted frequencies from the signals on said stipulated frequency, and
• in the communications unit, in the sending process, the indoor unit converts the baseband signals to intermediate frequency signals and sends the intermediate frequency signals to the outdoor unit via a coaxial cable, and the outdoor unit receives the intermediate frequency signals and converts the intermediate frequency signals to radio frequency signals and wirelessly transmits the radio frequency signals, and
• in the communications unit, in the receiving process, the outdoor unit converts received radio frequency signals to intermediate frequency signals and sends the intermediate frequency signals to the indoor unit via a coaxial cable, and the indoor unit receives the intermediate frequency signals and converts the intermediate frequency signals to baseband signals.
