Highest throughput rate recorded over the GX network in first round of over-the-air testing
23 February 2017: Inmarsat, the leading provider of global mobile satellite communication services, has announced a significant advance in the on-going development of its Global Xpress (GX) high-speed, global, mobile broadband platform.
In conjunction with VT iDirect, Inmarsat’s strategic technology partner for the GX platform, over-the-air tests of iDirect’s next-generation DVB-S2X technology achieved a forward channel throughput rate of 330 Mbps over a live Inmarsat GX satellite in orbit. The successful tests were conducted in January 2017 and leveraged iDirect’s next-generation iQ Series modem.
GX entered global commercial service at the end of 2015 and has already been adopted by major private and public sector organisations across the world as their new standard for seamless, reliable broadband connectivity.
“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. For example, it is a key enabler for the replacement of expensive airline InFlight-Entertainment systems (IFE) with more capable light-weight, connected streaming solutions that ensure all passengers on even the largest widebody aircraft can access streaming simultaneously.” Read More
New iQ Series remote spurs substantial efficiency improvements, approaching 6 bps/Hz
Herndon, VA, December 13, 2016 – iDirect, a world leader in satellite-based IP communications technology and a company of VT Systems, today announced it has completed a successful round of over-the-air tests on the Intelsat 29e satellite leveraging iDirect’s next-generation iQ Series remote. 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.
“These milestone tests prove how our goals of higher performance, better economics and simplified access can be achieved in operational networks,” said Mike DeMarco, Senior Vice President, Operations, Intelsat. “With iDirect’s iQ remote technology and Intelsat EpicNG capacity, service providers can transition onto our high performance network while leveraging their existing investment in hub infrastructure. This is an important achievement in enabling our customers to expand their businesses into new applications and geographies and realize their future growth objectives.” Read More
Revolutionary new ASIC chipset redefines performance and efficiency levels for satellite networks
Herndon, VA, November 30, 2016 – VT iDirect, Inc. (iDirect), a world leader in satellite-based IP communications technology and a company of Vision Technologies Systems, Inc. (VT Systems), today announced transformational DVB-S2X technology based on a powerful, customized ASIC (Application-Specific Integrated Circuit) chipset that will deliver revolutionary gains in data throughput and will power a new line of DVB-S2/DVB-S2X remotes called the iQ Series. iDirect is also introducing exponentially higher hub processing capabilities and virtualization of core gateway components to offer further gains in performance and efficiency and lower business costs.
iDirect’s DVB-S2X solution is the result of a significant investment to co-develop a state-of-the-art ASIC chipset that is customized to exploit the full capabilities of the DVB-S2X standard and optimized for the enhanced iDirect waveform. This next generation of technology will allow iDirect to leverage the benefits of today’s High Throughput Satellites (HTS) and the capabilities of next-generation HTS to unlock additional features of the DVB-S2X standard.
The iQ Series establishes a new model for satellite remote performance providing a future-proof strategy to deliver successive gains in performance and efficiency as network operators strive to keep pace with the launch of increasingly higher throughput satellites. Remotes can be continually reprogrammed over the air to increase network capabilities and throughput levels, driving a massive expansion of applications and setting new service level standards.
“We are incredibly excited to deliver DVB-S2X capabilities to our partners,” stated Wayne Haubner, Senior Vice President, Engineering & Emerging Technologies. “DVB-S2X represents a major opportunity for network operators to gain greater performance and efficiency to meet escalating user demands and realize lower business costs. We are currently performing over-the-air testing of our new DVB-S2X chipset, and results are demonstrating 500 Mbps of aggregate throughput. This technology will allow us to exceed 1 Gbps of throughput as we keep pace with future satellite developments.” Read More
Demo conducted with SpeedCast leverages iDirect’s DVB-S2X technology, enables aggressive data rates for SpeedCast managed service offering designed to extend reach of mobile networks
iDirect announced that lab tests with SpeedCast International Ltd. have demonstrated GTP/LTE traffic being transmitted over a single iDirect SatHaul™ terminal at speeds over 350Mbps on the downstream and 90Mbps on the upstream. This proof-of-concept is critical in helping SpeedCast achieve a leading position in cellular backhaul provisioning and helping mobile operators extend the reach of their services via satellite connectivity. iDirect is a world leader in satellite-based IP communications technology.
As demand for 4G/LTE service continues to escalate around the globe, SpeedCast is helping mobile operators scale their networks efficiently through delivery of a managed service offering, delivering high performance with no capital expenditures for the operator.
