Diversifying for and adapting to the emerging communication technology
AsiaSat 4, a Boeing 601HP satellite, is positioned at 122 degrees East orbital location that offers excellent 'look angles' over Asia and Australasia. Its C-band footprint widely spreads over the Asia-Pacific region with two focused Ku-band beams for East Asia and Australasia, and a steerable Ku-beam enabling greater flexibility in network connectivity.
