Coping with demands for interactive communication in the world communication and electric appliance markets.
Two-way Satellite System developed and being prepared to produce by Asia Pacific Satellite Industry Co., Ltd is an original model that adopts a CDMA standard and thus
technologically independent and provides cheapest two-way satellite set top boxes and gateways in the world.
In terms of data transmission, two-ways satellite service has a mutually complementary relationship with Internet services like ADSL, Cable, and BWLL.
In general, the two-way satellite service is not geographically constrained, and thus very useful in areas where ground network service is not easily able to reach.
Therefore the two-way satellite service and ground network service will complement each other and expand service areas.
