Company Limited (TCB) and IPSTAR Group
THAICOM satellites

The Company’s satellite fleet can be divided into 2 types: Conventional Satellite and Broadband Satellite (or High
Throughput Satellite, HTS)
 Conventional Satellite

A conventional satellite is a satellite that provides fixed satellite services (FSS), whereby a signal is transmitted from
an earth station, amplified, and retransmitted down to the other earth station(s) anywhere under the satellite’s
footprint, allowing broadcasters and telecommunications operators to benefit from the satellite’s nationwide and
cross-regional coverage.
 Broadband Satellite

A broadband satellite or High Throughput Satellite (HTS) is primarily designed to provide broadband Internet
access services (point-to-point). Through high-level frequency re-use and spot beam technology, HTS usually
provides much more total throughput than a conventional satellite for the same amount of allocated orbital spectrum,
thus significantly reducing cost per megabit per second (Mbps). In addition, HTS can offer services to government
and enterprise markets, as well as to terrestrial cellular network operators.
th
Regarding the Thai satellite concession ended on 10 September 2021 and the Thai government assigned National
Telecom Public Company Limited (NT) to manage satellites under the satellite concession. The Company has
leased THAICOM 4 and THAICOM 6 satellites capacity from National Telecom Public Company Limited (NT) and
the Company owns satellite capacity for THAICOM 7 and THAICOM 8.
