Latest iDirect modem pushes GX throughput to 330 Mbps

iDirect’s latest generation of modems, the iQ series iDirect’s latest generation of modems, the iQ series

Inmarsat has announced that it has completed tests of iDirect’s next-generation DVB-S2X technology on its Global Xpress (GX) Ka-band satellite network, achieving a forward channel throughput rate of 330 Mbps in over-the-air trials with a live Inmarsat GX satellite in orbit using iDirect’s latest iQ Series modem.

{mprestriction ids="1,2"}The successful tests were conducted in January 2017, and Inmarsat and iDirect intend to gradually introduce these improved capabilities to the GX network during 2018-19, for all end user sectors including maritime, aviation, government and enterprise. 

The two partners expect that Inmarsat’s next generation of GX satellites, due to launch around the end of this decade, will achieve throughput rates in excess of 500 Mbps, while maintaining backward compatibility for existing users.

“These tests demonstrate Inmarsat’s commitment to the continuing development of our GX platform, which will be supported by our next generation of satellites, which are already under construction” said Michele Franci, CTO of Inmarsat.

“It is important to note that these results were not achieved in laboratory conditions but over a live GX satellite in orbit. We will be able to increase the capabilities of the world’s first, globally available high-speed broadband network and meet the ever escalating bandwidth demands of users.”

“Our partnership with iDirect and the deployment of their DVB-S2X technology is key to enhancing the user experience of our GX customers, delivering even greater performance and maximising the commercial and operational benefits of their high-speed broadband connectivity.”{/mprestriction}
