Intelsat EpicNG: Delivering on the Promise of High Throughput with High Performance

Recent tests also confirmed that the Intelsat EpicNG platform exceeds performance expectations transmitting to and from a flat-panel antenna designed for a new class of small remotely piloted aircraft.

Since late March 2016, the first of the Intelsat EpicNG satellites, Intelsat 29e, has been carrying new and transitioning networks, as well as being used in next-generation tests. In all cases, customers and partners report that the platform is meeting and exceeding its performance and efficiency expectations across a range of applications. Whether the 165% efficiency improvement on current networking hardware or the up to 330% efficiency improvement on next generation ground networking technologies, Intelsat EpicNG is delivering on the promise of the high-throughput satellite era.

“Given the insatiable bandwidth demands of businesses operating around the world, we designed Intelsat EpicNG with our customers’ needs front and center,” stated Stephen Spengler, Chief Executive Officer, Intelsat. “Our design goal, focusing on efficiency and thus optimizing the throughput to the individual network users, has delivered immediate operating efficiencies for our customers. Our customers in the enterprise, mobility and wireless infrastructure sectors are using Intelsat EpicNG, in most cases with existing hardware, transitioning seamlessly onto our high performance network. Bottom line, our goals of higher performance, better economics, and simplified access are being proven in operational customer networks. Intelsat EpicNG will support our customers as they expand their businesses into new applications and geographies to realize their long-term growth objectives.”

Optimizing Throughput to the User

Intelsat and its customers now have performance experience with the Intelsat EpicNG satellite on six different satellite data networks, emphasizing the benefits of the open architecture, which allows customers to choose the data networking hardware best suited to their applications and business plans. With the advanced capabilities of the Intelsat EpicNG digital payload, customers are also achieving advanced flexibility in terms of satellite resource allocation, including functionality to cross-connect C-band to Ku-band services on a dynamic basis, and carrier-level optimization resulting in much higher performance levels. The Intelsat EpicNG digital payload also creates an enhanced environment for battling interference and mitigating jamming with respect to government applications.

Unlocking New Applications

With over 30 customers already using Intelsat 29e, the three design objectives of the Intelsat EpicNG platform—backwards compatibility, open architecture and optimized spectral efficiency—are yielding immediate benefits. Field tests are also providing evidence of the potential to unlock new applications in sectors not currently served by satellite.

Our subsidiary, Intelsat General Corporation, performed tests with a government customer using a 6” by 6” Gilat airborne terminal, BlackRay 71 with a flat-panel antenna, designed for a new generation of small Class III unmanned aircraft system (UAS). The customer sent data from Gilat’s small airborne antenna to the recently launched Intelsat 29e satellite at a rate of 3.9 Mbps. This compares to an uplink rate of about 1.8 Mbps from the small antenna to a conventional Ku wideband satellite. This link was effectively 2 times the rate of and almost 3 times more efficient than traditional widebeam satellites. Transmitting full-motion high-definition video from antennas of this size is unprecedented in the world of satellite communications, and has applications in both military and commercial sectors.

Transitions Seamless; Advanced Features Tested

Operationally, Intelsat EpicNG service activations have been seamless, as customers easily transitioned to or brought up services on the platform. Further, the Intelsat 29e digital payload features are in wide use, with customers easily operating between both wide and spot beams. Intelsat’s teleport ground station RF calibration and performance were validated as were the platform’s forward and return service performance.

“Based upon our experience with live networks, we’re proving every day that the higher performance, improved economics and simplified access enabled by Intelsat EpicNG will position enterprise, fixed and mobile network operators and maritime and aeronautical service providers to rapidly scale networks on a global basis, while staying ahead of explosive data-performance requirements. Our ecosystem is engaged and energized by the expected results and the benefits to be realized by our global customer base in the enterprise, wireless, mobility and government sectors,” said Kurt Riegelman, SVP, Sales and Marketing, Intelsat.
