The Future of VSAT Is Multiservice

The Future of VSAT Is Multiservice
Gone are the days when a satellite platform will be used for one purpose!


The global VSAT market has traditionally consisted of specialized service providers, each focused on specific vertical markets and regions. Until now, specialization and customer intimacy have been the key differentiators for most vendors. 

However, as the industry consolidates and bandwidth demand skyrockets, economies of scale will become the primary competitive advantage. In addition, with the advent of High Throughput Satellites (HTS), satellite operators will be compelled to start offering managed services (in Mbps) across multiple spot beams and vertical markets.

Key Characteristics of a Multiservice Platform

Supporting a wide range of applications, while maximizing economies of scale, requires a flexible, efficient and scalable multiservice VSAT platform, with five key characteristics; see image.

Newtec’s unique Newtec Dialog® multiservice platform offers these key enablers and supports an unparalleled range of applications. Everything from Business to Consumer (B2C) to high-end cellular backhaul and mobility can be supported on this single platform.

Modem Types

It is key to offer a range of modems that meet diverse technical requirements and price points. 

At Newtec, we provide:

  • For the lower-end, the Newtec MDM2000 line of modems (like the Newtec MDM2200 IP Satellite Modem) provides a cost-effective B2C solution, based on the robust MF-TDMA technology. MF-TDMA is optimized for bursty traffic and can scale to hundreds of thousands of terminals.
  • For the mid-range enterprise market, the MDM3000 series of modems, coupled with Newtec’s patented Mx-DMA™ return technology (Cross Dimensional Multiple Access), provides the perfect balance of cost and performance. Mx-DMA assigns dedicated SCPC carriers to each terminal but adjusts the symbol rate, frequency, MODCOD and transmit power every second (for every terminal) in response to variable bandwidth demand and changing radio frequency conditions. This unique approach delivers the efficiency of SCPC with the dynamic bandwidth allocation capabilities of MF-TDMA. The MDM3000 series can also operate in MF-TDMA or SCPC modes, further increasing its versatility.
  • For several years, we have offered our MDM6000 series to the high-speed and point-to-point backbone market, supporting speeds up to 425 Mbps (duplex) and MODCODs up to 256APSK. The MDM6000 was the first modem on the market to support the new DVB-S2X standard. It incorporates Newtec’s Bandwidth Cancellation (BWC) technology that allows two carriers to be transmitted in an overlay fashion, providing record-breaking spectral efficiencies.


Something New Is Coming

In order to address the high-end backhaul and mobility markets, Newtec is developing next-generation Newtec Dialog modems that will offer industry-leading performance and efficiency. Supporting the latest DVB-S2X waveform, wideband carriers and unprecedented throughput, Newtec Dialog will maximize the capabilities of upcoming HTS. From a commercial perspective, it is key to offer a flexible licensing model and a modular hub architecture which enables service providers and satellite operators to start small and “pay-as-they-grow”. With a simple upgrade path, Newtec customers can add outbound carriers, return technologies and throughput capabilities to efficiently address new opportunities and markets.

The VSAT industry is undergoing a radical transformation, both from a commercial and technical perspective. The next generation of service providers will be required to address an unprecedented range of applications while driving massive economies of scale. Having the right multiservice platform will be the key to success in this new VSAT paradigm.
