iDirect iQ Series remote spurs substantial efficiency improvements, approaching 6 bps/Hz

Satellite-based IP communications technology provider VT iDirect, Inc. (iDirect) has completed a successful round of over-the-air tests on the Intelsat 29e satellite leveraging iDirect´s next-generation iQ Series remote, the company said.

iDirect´s ground infrastructure platform and iQ Series modem technology combined with Intelsat EpicNG satellites yielded a throughput rate of 5.71 bps/Hz — another demonstration of the up to 330% efficiency performance gains on the Intelsat EpicNG platform. This allows iDirect and Intelsat customers to exploit the full capabilities of the DVB-S2X standard so they can more efficiently meet demands for high-speed bandwidth.

The tests were conducted in Intelsat´s teleports from Oct 26-28, 2016 on the Intelsat 29e satellite, running on an iQ remote installed in Atlanta and iDirect´s new Universal Line Card and Hub chassis installed in Mountainside, MD. The successful tests included the operation of DVB-S2X carriers with 64APSK, 128APSK and 256APSK modulation and coding, and roll-off factors of 5%. The user data tests demonstrated substantial efficiency improvements reaching an industry-leading 5.71 bps/Hz in throughput per remote.
