A satellite is a communication device that is placed outside of space and orbits the earth where the function of a satellite is as a microwave or repeater signal so that it is accessed by customers or users of telecommunications services to exchange information for devices connected to earth stations. This paper discusses the use of satellites with a ratio of 5G to be implemented in Indonesia with a comparison of the costs required for satellite planning. High Throughput Satellite (HTS) in 2021 and the palapa ring project.
Satellite communication system is a communication system that connects the source with the purpose of communication using satellite as its medium. While communication satellites are communication devices placed on satellites with the aim of telecommunications and orbiting the earth. Satellite communication systems are divided into two segments, namely ground segment (earth station) and space space (satellite). The ground segment works to send information signals to satellites using uplink frequencies and satellites work on repeaters that will send amplified signals towards the earth using downlink frequencies.
The use of HTS (High Throughput Satellite) aims to provide superior requirements at a lower per-bit cost. The sponsored capacity is the ratio of Gigabit per second (Gbps) compared to the capacity on the FSS satellite (Fixed Satellite Service). The need for throughput demanded by uptake of broadband internet in emerging and relocated areas. HTS Due to its large capacity to be used for data communication, satellites via HTS will be an important part of the 5G infrastructure going forward.
Indonesia has diverse physical conditions in the region, so it will need broadband that is able to meet existing conditions. Satellite communication systems have the advantage of providing services without depending on existing conditions on land. HTS can be one solution in supporting the provision of broadband services. However, there are obstacles, namely as a mobile broadband next generation network (5G) service which will be limited to urban centers where terrestrial backhaul such as optical fiber or microwave is available. But of course operators will continue to expand service coverage to rural areas thereby creating opportunities for high throughput satellites to support 5G network backhaul.
One of the key drivers of communication satellites for 5G is IoT. There are two pillars in realizing the 5G vision. First is ensuring availability, reliability and durability. Network recruitment generates complex problems that require security of services or good content on heterogeneous networks managed by different entities. The second is the problem of energy efficiency. The goal is to reduce energy by 90% on energy from now to 2020 without reducing performance or increasing costs. Thus 5G network design becomes a complex task involving links and areas of shared efficiency and energy efficiency.
Indonesia with a group of islands is a separate challenge in deploying 5G so it requires backup, which is satellite. So that the implementation of the 5G satellite is still needed in Indonesia going forward. In the concept of 5G satellite technology, using IBP HTS will be upgraded to IBP Plus (optical fiber network and HTS) which is expected to provide “truly-fully broadband” services along with national R&D programs and strengthening human resources. Without HTS involvement in Indonesia’s broadband implementation, broadband telecommunications services are not yet complete. HTS satellite development requires cooperation with other satellite operators in order to obtain the availability of filing, optimization of investment costs, and efficiency of service costs. In addition to efficiency, cooperation with domestic operators on the scope of service is also needed to ensure service quality in accordance with customer expectations.
