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.
One of the biggest healthcare issues of many countries today is that the poor level of medical services in rural and remote regions. Rural areas generally have worse medical services compared to urban areas and large cities. This is a big problem especially since the demand for professional medical services and medical aid in rural areas is increasing, while medical services have not been able to keep up.
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.
Wireless communication is now a very integral part of our daily lives with growth occurring in every area of the world. Cellular mobile operators are always trying to increase their cellular coverage. However, there are still millions without access to cellular communication. There are many who live and work in rural and remote areas that do not have wireless coverage due to the high cost of terrestrial backhaul, which is a very significant barrier to cellular expansion.
The use of mobile devices to communicate is now a necessity for most people throughout the world. Mobile telephony allows us to get in touch with family and friends, and allow access to other important tools that we need in our daily lives. Today’s mobile communication systems are capable of not only making calls, but also storing data, taking pictures, accessing the internet, and many other functions that make them invaluable.
If you are following technology news, you probably know of the advances in high speed Internet platforms such as LTE and direct fiber to home technologies. Older connectivity platforms such as satellite communication thru VSAT may seem old and outdated. However in many countries, VSAT networks are actually very much desired for the advantages they offer in Internet broadband access and corporate WAN connectivity.
