High Throughput Satellites (HTS) aim at providing superior capacity at a lower cost per/bit. The targeted capacity is in the hundreds of Gigabits per second (Gbps) compared to a few Gbps for FSS satellites. The need for such throughput is fueled by the uptake of broadband Internet in emerging and remote regions. HTS leverages frequency re-use across multiple narrowly focused spot beams (a few hundred kilometers) as opposed to traditional satellite technology which is based on a broad, single beam (a few thousand kilometers). Frequency-reuse maximizes the available frequency for transmissions.
While HTS is usually associated with Ka-Band transmission only, there are several different types of HTS in reality. All of them leverage frequency re-use and spot beams. Eutelsat’s KA-SAT is based on Ka-Band. O3b’s Ka leverages a Medium-Earth Orbit (MEO) constellation, which reduces latency and is particularly suitable for interactive applications. As for Intelsat’s EpicNG, several bands are available: C-, Ku- and Ka-Bands, as well as wide beams and spot beams with the frequency reuse technology.
The increased capacity makes HTS an ideal solution for satellite mobile backhauling where mobile traffic is growing rapidly with the help of bandwidth hungry applications such as video. We have been at the forefront of HTS, working closely with the operators and expanding our suite of products to encompass HTS capability and performance for your rural remote areas’ networks.
