STM Group Meshes It All Together

STM Group offers the first DVB-RCS compatible mesh VSAT network system as an extension of its SatLink® product platform. The SatLink 1910 Mesh VSAT is enabled using a simple plug-in card upgrade to the current SatLink 1910. This equips the VSAT to receive burst communications on four, concurrent MF-TDMA carriers, which assures non-blocking mesh networking performance for voice and data to typical end-user sites. Also this year, STM will also introduce mesh gateway systems within the SatLink product line to serve as high-traffic concentration points; these systems concurrently transmit and receive over many DVB-RCS compliant MF-TDMA carriers. All SatLink VSAT systems also receive network control and user data via DVB-S2 ACM compliant TDM carriers. The SatLink mesh product offers dynamic IP routing in large, full-mesh environments with QoS and TCP acceleration applied. This capability allows the terminals to establish routes automatically, based on current traffic patterns and link conditions, and to allocate MF-TDMA carrier capacity using differentiated service criteria for voice, interactive video, critical user data and best-effort traffic accordingly. The SatLink product is optimized for IP-based telecom applications, as well as private networks requiring concurrent single-hop connectivity among hundreds or thousands of sites. Mesh network capabilities will also be offered by STM’s teleports, allowing for rapid deployment of small mesh networks, as well as cost-effective point-to-point links using DVB-RCS compliant MF-TDMA VSATs.
