STM Group Announces Technology Breakthrough with SatLink 2000 VSAT

STM Group, Inc. announced its SatLink 2000 VSAT Indoor Unit (IDU) with breakthrough technology for meeting next generation requirements in high-performance satellite networks.

The SatLink 2000 supports Internet Protocol (IP) throughput up to 30 Mbps and operates on DVB-S2 carriers at information rates over 160 Mbps. The compact, lightweight SatLink 2000 is suitable for interactive data, voice over IP, and IP video conferencing applications in the government and large corporate markets. It is also cost-effective for small business applications and premium residential services for Internet access, high-definition voice, and IPTV.

The SatLink 2000 has been certified by SatLabs as DVB-RCS compliant to the latest version of the standard. It provides burst-mode MF-TDMA for return link communications at up to 5 Mega symbols per second. The use of Adaptive Coding and Modulation (ACM) is fully supported on the DVB-S2 forward link and integrated with SatLink QoS to boost average network efficiency by 150% or more, while protecting high-priority or delay sensitive applications during rain fades. Built-in value-added features include: TCP and Web acceleration; IP QoS, routing and header compression; plus protocol support for NAT, IGMP, VLANs, VPNs, DHCP Server, and DNS caching. For user traffic security, the design supports AES-256 encryption at Layer-2.

The future-proof design of the SatLink 2000 will also deliver the next generation of DVB-RCS standards currently being finalized in the DVB Working Group. This allows for ACM “per-burst” with a 16-state Turbo Code FEC and many other advanced features. These innovations increase return link spectrum efficiency and IP throughput by up to 175% vs. the TDMA architectures common to most VSAT networks today.

“The SatLink 2000 is the next-generation of high-performance VSAT IDU ideal for new broadband services, such as those being planned for high-throughput Ka band satellites around the world.” said Richard Forberg, VP of Marketing for STM. “The days when VSAT connections were limited to one or two Mbps are gone. With the SatLink 2000, individual VSAT traffic loads can exceed 20 Mbps outbound, and 10 Mbps inbound, with all of it dynamically assigned per IP application.”

The SatLink 2000 is currently shipping to select STM customers and channel partners.
