The demand for Broadband Internet by satellite is indisputable, as is the demand for more communication bandwidth in general. Internet communications bandwidth requirements continue to grow at about 50% annually. ViaSat-1 is a very advanced Ka band Internet satellite. The amount of bandwidth enabled by ViaSat-1, equipped with ViaSat's "SurfBeam" networking system, is unparalleled. Total throughput is designed to be over 100 Gigabits per second, which is more capacity than the current North American fleet of two-way Ka, C and Ku band combined. In 2010, Ka-Sat will launch a satellite to provide similar service in Europe.
