Our Satellite Technology

Activ8me Corporate uses the IPSTAR system which is comprised of a gateway earth station communicating over the IPSTAR satellite to provide broadband packet-switched communications to a large number of small terminals with network star configuration.

A wide-band data link from the gateway to the user terminal uses an Orthogonal Frequency Division Multiplexing (OFDM) with a Time Division Multiplex (TDM) overlay. These forward channels employ highly efficient transmission methods including Turbo Product Code (TPC) and higher order modulation (L-codes) for increased system performance.

In the terminal to gateway direction or return link, the narrow-band channels employ the same efficient transmission methods. These narrow-band channels operate in different multiple-access modes based on bandwidth usage behaviour, including Slotted-ALOHA, ALOHA, and TDMA for STAR return link waveform.
