Satellite modem targets high-end mobility, trunking and HTS markets

Newtec, a specialist in designing, developing and manufacturing equipment and technologies for satellite communications, has announced the launch of its most advanced VSAT modem – the first on the market to support wideband DVB-S2X.

The Newtec MDM5000 Satellite Modem is capable of receiving forward carriers of up to 140 MHz, and processing over 200 Mbps of throughput. On the return channel, it supports SCPC, TDMA and Newtec’s unique Mx-DMA, up to 75 Mbps.

With forward symbol rates from 1 to 133 Mbaud and coding up to 256APSK, the MDM5000 will boost efficiency and performance on legacy satellites while unleashing the potential of next-generation High Throughput Satellites (HTS). As the latest addition to the Newtec Dialog multiservice platform, the MDM5000 is designed to handle a wide range of IP services, including: Internet and Intranet access, Voice over IP (VoIP), mobile backhauling and trunking, along with video contribution and multicasting.

“The MDM5000 Satellite Modem represents another milestone in Newtec’s long history of innovation. By introducing the industry’s first DVB-S2X VSAT modem, we plan to enable our customers to better serve the high-end mobility and trunking markets, while maximizing the benefits of HTS,” said Newtec CEO, Serge Van Herck. “The addition of the MDM5000 to our comprehensive modem portfolio, and our three return technologies, ensures that Newtec customers will always have the optimal solution at their disposal, for every application and price point.”

Having the choice between Mx-DMA, SCPC and MF-TDMA within a single modem, gives network operators the flexibility to address multiple markets, adapt to evolving business models and quickly respond to new opportunities and customer requirements.

Newtec’s unique Mx-DMA return technology delivers the efficiency of SCPC with the dynamic bandwidth allocation capabilities of MF-TDMA, offering more than 50% efficiency gains. Mx-DMA is ideal for mid to high-end applications, with variable return rates up to 75 Mbps, including: cruise ships, oil rigs, super yachts and cellular backhauling. For applications that require fixed data rates, like file/video contribution, SCPC provides highly efficient, dedicated return channels, up to 170 Mbps. At the other end of the spectrum, MF-TDMA is optimized for low-rate, overbooked and bursty traffic profiles, like back-up circuits and occasional use services.

As with previous Newtec Dialog modems, the MDM5000 incorporates Layer-3 routing, advanced Quality of Service (QoS), TCP acceleration, pre-fetching, compression and encryption. However, the MDM5000 also supports a new Layer-2 mode, facilitating integration with various networking topologies and routing protocols, like MPLS and BGP. It also comes equipped with dual demodulators, for future seamless beam switching on HTS networks.

“For service providers, targeting high-end verticals like cruise ships, oil rigs, and cellular backhaul, the MDM5000 is a game changer,” added Kevin McCarthy, VP of Market Development at Newtec. “Up to now, the only alternative was to combine multiple low-end MF-TDMA modems, or resort to expensive SCPC circuits to address the extreme throughput demands of these high-value markets. The MDM5000, paired with our Mx-DMA technology, will bring welcome relief to these customers and strategically position them for the transition to HTS.”
