Broadband internet, by ADSL, fiber optic, and CATV circuit has become very popular. However this service can not be shared in the depopulated area, where Broadband service business is difficult to materialize. BBISS satellite has been planned to provide the Broadband service to these un-equipped areas. In order to do so, a wide Ka frequency band is utilized and moreover, multi-beam antenna is adopted to realize the improvement of the efficient frequency reuse and to succeed in earth station antenna miniaturization. As for the problematic matter in use of the Ka-band due to great rainfall attenuation will be solved by use of adaptive code modulation method and realize high availability, and high=speed information speed will be provided in case of fine weather by maintaining the necessary minimum margin. This paper introduces best effort service by BBISS with such features.
