摘要

Satellite broadband services appear to be moving toward Ka-band frequencies in North America, Europe, the Middle East and elsewhere but Ku-band is not , ready to throw in the towel, ac-corctmg to Ka- and Ku-band satellite operators.This is especially true in East Asia, where Thailand's Thaicom operator, after a slow start due in part to landing-rights issues, has now found traction with its IPStar broadband satellite, which uses Ku-band.IPStar, launched in 2005, was a precursor for the mainly Ka-band high-throughput satellites that are in operation or planned over the United States, Europe and Australia. With 45 gigabits per second of throughput, IPStar - built by Space Systems/Loral of Palo Alto, Calif. - dwarfed other commercial satellites then in orbit. Since then, Loral and Astrium Satellites of Europe have built Ka-band broadband satellites with far more throughput.
