The IPSTAR network configuration is based on Gateway STAR topology. A user terminal receives and transmits signals from/to a Beam, which connects with a gateway. The gateway, in turn, connects to other networks such as Internet backbone, telephone network, corporate headquarters, or other IPSTAR Gateways. Most countries under IPSTAR's service would have one or multiple Gateways. This allows efficient integration of users into terrestrial networks for various applications. There are a total of 18 gateways planned for IPSTAR services.

IPSTAR's Modulation and Coding technology provides an efficient use of RF power and bandwidth, allowing a high and flexible digital transmission rate, which enables the use of small antennas and transmitters.
