The satellite industry has a very good record of technological innovation, but it is mainly focused on only one aspect, which is maximizing the use of the limited satellite spectrum resource. Satellite spectrum has a significantly higher cost compared to terrestrial bandwidth such as DSL and fiber, and this high cost has driven the evolution of VSAT systems to efficiently use bandwidth. The satellite evolution has been especially accelerated during the introduction of IP VSATs, and the industry has innovated greatly to achieve excellent IP bandwidth efficiency. IP bandwidth efficiency will always remain important for the industry, but the focus for the next wave of satellite innovation will probably come from a very different direction.
High Throughput Satellites (HTS) are poised to deliver much higher capacity than traditional satellite services at a mere fraction of the cost. Today, HTS can provide more than 100 GBps of capacity this is more than 100 times the capacity offered by conventional Ku-band satellites. HTS is based on spot beam technology which enables frequency re-use across multiple narrowly focused spot beams. This results in a very significant increase in capacity for the same amount of allocated spectrum, allowing satellite operators and providers to lower costs.
Understanding High Throughput Satellites
High throughput satellites (HTS) are communications satellites that provide 10 or more times the total throughput of a regular fixed communications satellite for the same amount of allocated spectrum. New high throughput satellites today can provide more than 100 GBps of capacity, which is more than 100 times the capacity offered by a conventional Ku-band satellite.
