Abstract: A base station system includes a base station apparatus (1) and a wireless transmission apparatus (2). The base station apparatus (1) communicates with mobile stations. The wireless transmission apparatus (2) communicates with the base station apparatus (1) and wirelessly communicate with another apparatus in order to connect the base station apparatus (1) to a mobile backhaul network. The base station apparatus (1) includes a solar cell panel (15) for generating operating power of the base station apparatus (1), and a storage battery (14). The wireless transmission apparatus (2) includes a solar cell panel (25) for generating operating power of the wireless transmission apparatus (2), and a storage battery (24). The base station apparatus (1) and the wireless transmission apparatus (2) wirelessly communicate with each other. This can provide, for example, a base station system that can be easily installed and has high tolerance to accidental or intentional damage to cables.

Abstract: Condensation water occurring within a container box (300) is discharged to the outside thereof, thereby keeping the inside of the container box (300) at a low humidity with no condensation water therein. The container box contains an electric circuit (210) therein and is sealed. The container box comprises: a minute discharge aperture (322) formed at a lowermost part of the container box (300); and a discharge valve (330), the discharge valve (330) being a check valve for closing the discharge aperture (322). Only when the an internal pressure of the container box (300) becomes higher than an external pressure thereof by a predetermined value or greater, does the discharge valve (330) opens to discharge the liquid present inside of the container box (300). The discharge valve closes to keep the airtightness of the container box (300) at all other times.

Abstract: The radio communication system includes: a transmitter that transmits a first polarized signal and a second polarized signal to a receiver and terminates the transmission of the second polarized signal in accordance with an instruction from the receiver; and the receiver that receives the polarized signal from the transmitter, determines whether or not a reception quality of the second polarized signal becomes lower than a threshold value, and issues an instruction to the transmitter to terminate transmission of the second polarized signal to the transmitter when the reception quality becomes less than the threshold value.
