ST Engineering iDirect boosts VSAT modem up to 600Mbps on shared capacity networks

ST Engineering iDirect, a provider of modem and network technologies for maritime VSAT systems, has reported that it has achieved an aggregate speed of 600Mbps in testing on its MDM5010 satellite modem for shared bandwidth capacity networks.

The company says that these speeds have previously only been achieved with single channel per carrier (SCPC) point-to-point modems, and that it will now be able to combine the efficiencies of bandwidth-sharing with more demanding throughput requirements.

The MDM5010 modem can now deliver three times more return throughput at 200Mbps using Mx-DMA return technology, coupled with up to 400Mbps on the DVB-S2X outbound for an aggregate speed of 600Mbps.

“This is of huge significance, especially for the maritime and cell backhaul markets where demand for throughput and performance is increasing exponentially,” said Bart Van Poucke, Vice President, Products, ST Engineering iDirect.

“With the need for very high speeds on the inbound, we pushed the boundaries of our Mx-DMA return technology to break the speed limit while increasing the flexibility and operational efficiencies that our customers depend on.”

“This breakthrough will deliver the highest quality connectivity experience for users and enable our customers to offer the widest range of applications to expand their market share.”

ST Engineering iDirect’s Mx-DMA return technology, a core feature of the Newtec Dialog platform acquired by ST Engineering in its €250 million buyout of Newtec in 2019, is a dynamic waveform which enables service providers to share satellite capacity more efficiently over a group of satellite modems.

In this latest Dialog Release 2.2.3, the maximum return symbol rate per modem increased from 20Msps (millions of samples per second) to 68Msps, which equates to an increase in throughput from 70Mbps to 200Mbps on the inbound.

Satellite service provider Speedcast was involved in the testing of the updated MDM5010 system, having already deployed the underlying technology for customers including cruise vessels and mega yachts.

“Speedcast has embarked on a strategic initiative to completely rearchitect our global mobility network, building a platform that can support the most demanding of customer operations, and any application requirement. We view Dialog as a fundamental building block of Speedcast’s new Unified Global Platform,” said Chris Hill, Chief Technology Officer, Speedcast.

“The combined strengths of our overarching architecture and best-of-breed technology means that we can deliver the speeds and flexibility that meets our clients’ emerging requirements and operational needs across multiple verticals, including fixed terminals, rapid deploy terminals and mobility.”

“From a technical perspective, the MDM5010 is an important part of the upper bound of our network platform, allowing us to deliver satellite links that are impressive not only in terms of Mbps, but also in terms of packet per second and simultaneous session counts. Many of our clients are already benefiting from this latest generation technological innovation, and we look forward to the further deployment to customers as our network re-architecture continues to progress.”
