Bandwidth Efficiency at Many Levels
Beyond the superior efficiency of DVB-S2 forward links, SatLink offers: return channel spacing down to 1.2x, header compression, section packing, advanced MF-TDMA resource control and VSAT capacity request methods, plus extensive bandwidth management tools assuring no wasted resources in the network.
Comprehensive IP Networking Features
SatLink hubs integrate full-featured IP routing, VPN tunneling and VLAN options, TCP acceleration, plus other value-added functions per request.
Advanced Traffic Shaping with QoS
Advanced traffic shaping on forward links gives added benefit for delay or jitter sensitive applications like VoIP, video conferencing & streaming.
Industry-Leading RLS & FLS
Fully integrated Forward Link and Return Link Systems deliver many further cost and operational benefits, including: larger TDMA Carrier Groups, space and power savings, custom framing and custom Carrier Group configurations for highly optimized mesh and star topology configurations.

High-Availability for Maximum Up-time
Critical components are implemented in either 1:1, N:1 or N:M redundant configurations with fast-failover, and SW updates may be done on-the-fly, for up-times exceeding 99.99%.
ACM and Rain Fade Mitigation
Adaptive Coding and Modulation (ACM) on forward links and adaptive FEC and symbol rate on return links increase bandwidth efficiency and improves link margins to mitigate rain fades.
Traffic Engineering for Large Networks
SatLink enables traffic engineering and effective hub sharing by controlling bandwidth consumption and QoS policies by VSAT Group.
Multi-Beam & Multi-Band Scalability
Support for multiple beams, across multiple satellites on multiple bands (C, Ku, Ka, EHF), including cross- strapped transponders, adds versatility and scalability.
Industry-Leading NMS & NCC
STM’s database-driven NMS and NCC software optimize performance and VSAT provisioning with ease of use, and support both star and mesh topologies.
