Two-Way Satellite Set Top Box and Central Stations System |
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.
