New SatLink unit

STM Group has presented its newest VSAT indoor unit, SatLink 2910, which it says builds on the technology in its 2900 model while tripling its throughput.

Multicast or streaming IP data is supported at rates up to 150 Mbps, says the Californian engineering company.

The SatLink 2910 can be used with all satellite bands but is especially suited for Ku- and Ka-band, according to STM. Adaptive Coding and Modulation (ACM) is performed on DVB-S2 forward links and RCS2 return links (per burst).

As in all SatLink networks, its features include integration of traffic shaping with ACM controls, integrated link encryption using AES-256, VLAN tagging with private networking extensions, and mesh networking among VSATs.

Additionally, the SatLink 2910 includes a built-in 8-carrier mesh TDMA burst receiver.

The new product is a 1U rack-mountable unit. It uses the VSAT Antenna Control Protocol (VACP), an open protocol developed by STM which enables beam and satellite handovers for mobile VSATs when roaming or experiencing blockages.

Like other SatLink VSATs, it is configured and automatically controlled from the Hub. The SatLink 2910 will be commercially available in Q3, 2013.

“STM expects the launch of the SatLink 2910 to help continue the strong triple-digit percentage growth in market share for SatLink and DVB technology in maritime, oil & gas, and other professional markets where the best quality, throughput, and the best overall link performance is required,” said Bjorn Platou, executive VP and general manager for Europe.

STM also announced a development project it is working on regarding a very high throughput, integrated TDM/TDMA Hub modem, supported by the Norwegian Space Centre and the European Space Agency.

The aim is to produce a compact 1U rack-mountable unit with 350 Mbps of IP throughput over DVB-S2 forward carriers with symbol rates up to 200 Msps.
