THAICOM 4 is a multiple spot beam bent-pipe satellite without on-board regenerative payload. The combination of innovative ground and space technologies allow the delivery of cost-effective satellite broadband for any location without access to terrestrial infrastructures. THAICOM 4 is the first high throughput satellite ever launched.
The THAICOM 4 broadband satellite system is composed of a gateway earth station communicating over the satellite to provide broadband packet-switched communications to a large number of user terminals with network star configuration.
Traditional satellite technology utilizes a broad single beam to cover entire continents and regions. With the introduction of multiple, narrowly focused spot beams and frequency reuse, THAICOM 4 is capable of maximizing the available frequency for transmissions; thus improving efficiencies and increasing bandwidth by a factor of twenty compared to traditional Ku-band satellites.
