Optimizing HTS From The Ground Up

Article

High Throughput Satellites (HTS) have crossed an inflection point in recent years and, looking forward, there is clear evidence that points towards major growth in data services making use of HTS capacity compared to Fixed Satellite Services (FFS). Over time, there has been a shift away from C-band and FFS Kuband, towards more cost-effective networks – Ku- and Ka-band. 

Where HTS services were initially focused on broadband services and enterprise, today the ability to deliver high performance and reliable services at affordable price points has resulted in fast HTS adoption in all vertical market areas, including cellular backhaul, maritime, aero and energy services. In the cellular backhaul market, Northern Sky Research (NSR) spotted signs of price elasticity: lower service prices are offset by an increased demand for services by Mobile Network Operators (MNOs). Although the traditional wide beam-based services remain relevant, the growth is mainly for HTS based services. 

Embracing the Evolving HTS Value Chain

The make-up of the HTS architecture, with its large number of beams and multiple gateways, has resulted in a shift in the value chain to deliver data services to the end-customers. The HTS ground infrastructure that converts the satellite MHz to Mbps is now put in place by satellite operators or tier-1 service providers. These operators can offer wholesale, managed services to regional or local service providers, who then use their local expertise and network of relationships to deliver the tailored value-added services that end-users require.

A key factor that enables this adapted value chain is the introduction of optimized business models enabled by the ground segment technology. This allows each player in the value chain to focus on its core business, while still providing the required flexibility to its partners. VSAT operators, previously running services on their own infrastructure, are evolving into Virtual Network Operators (VNO). Essential for these VNOs is the ability to buy HTS-optimized, ‘cross-beam’, wholesale managed services, taking away the complexity of requiring dedicated capacity in each individual spot beam. This is where the HTS-optimized multiservice platforms such as Newtec Dialog® step in to provide these VNOs service providers with networking flexibility, Quality of Service (QoS) and throughputs to serve even the most demanding customers in different verticals with tailored high performance and value added services at very competitive price points.

Making the Most of HTS

The Newtec Dialog multiservice platform is Newtec’s answer to optimizing HTS technology. The introduction of HTSs with spot beam technologies is an innovation in the sky, and with all that potential, it is important to get the most out of HTS and achieve the best possible cost per bit. This can be done by maximizing the efficiency and effective throughput of the satellite and spot beams. 

“For Newtec, it is all about our complete HTS product portfolio, which aims to empower our customers to cost-effectively deliver improved services in any vertical market and benefit from the efficiencies and throughputs enabled by HTS spot beam technology. We want to enable our customers to address a wide range of applications and verticals to monetize their satellite capacity in the best possible way."

Newtec’s highly scalable solution is prepared for the evolving value chains of HTS and has advanced VNO and wholesale bandwidth management capability. The platform offers maximal service revenues at minimal risk, offering multiservice broadband to the most demanding applications and end-user operations, all via one platform.

In the forward link, legacy DVB-S2, with carriers up-to 100 Mbaud, has been replaced with DVB-S2X, supporting 500 Mbaud carrier, allowing operation of a typical 250 or 500 MHz HTS satellite beam in single carrier mode. This creates increased efficiency and throughput, higher service availability and optimal statistical multiplexing, returning higher revenues and higher margins. Return link technology has also evolved from the legacy MFTDMA towards more advanced and efficient technologies with a higher throughput, such as Mx-DMA®, delivering up to 75 Mbps from a single remote with bandwidth allocation flexibility of MFTDMA and at SCPC-like efficiencies.

There are also plenty of options available that increase productivity and operational efficiency, such as the automation of backend processes through Application Programming Interface (API) integration with the service platform, Point&Play® smartphone apps for easy and high quality terminal installations without the need for Network Operations Center (NOC) intervention, and operational business and service planning tools such as the Satellite Network Calculator which tailors end-user customized services within the HTS footprint using the most optimal terminal ODU.

Modems for Multiple Market Segments

Newtec’s DVB-2SX wideband VSAT Modem Portfolio combines four best-in-class modems to optimally meet the requirements of any market or applications. Each of the modem types can be easily integrated into one single satellite network to bring about significant efficiency, flexibility and Capital Expenditure (CapEx) and Operational Expenditure (OpEx) savings, all managed via the Newtec Dialog platform.

The modems are unique in their capability to address wideband HTS transponders up to 500 MHz providing further efficiency and operational gains. Satellite service providers choosing these modems can either boost the efficiency and performance of legacy satellites or fully unleash the potential of next-generation HTS.

Flexibility is key for any service provider’s business strategy to enable high-efficiency services to be delivered today and in the future. The shift towards HTS solutions will only continue as the industry strives towards cost-effective and reliable services that vertical markets need, and with award-winning technology like Newtec Dialog at the helm, it’s sure to happen quickly.
