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.
