NOVELSAT and Spacecom Exhibit World’s Highest Spectral Efficiency over AMOS-17

NOVELSAT and Spacecom Exhibit World’s Highest Spectral Efficiency over AMOS-17

HIGH-CAPACITY DATA LINK EXCEEDED 10 BIT/HERTZ

Ra’anana and Ramat Gan, Israel – September 14, 2020 – NOVELSAT, a global leader in content connectivity over satellite, and Spacecom (TASE: SCC), operator of the AMOS satellite fleet, announced today the successful demonstration of high capacity satellite transmission with spectral efficiency of 10.5 bit/Hz over AMOS-17 high performance HTS utilizing NOVELSAT DUET™ CEC™ (carrier-echo-cancellation) band reuse technology.

Operating over AMOS-17 Ka HTS and Ku beams, NOVELSAT modems established a symmetrical link, reaching 64APSK modulation with 9/10 FEC rate and 2% roll-off, achieving data rate of 854Mbps over of 81.6MHz bandwidth and 753Mbps over 72MHz bandwidth, demonstrating spectral efficiency of 10.5 bit/Hz.

This extraordinary performance was achieved without any power backoff or additional satellite padding, and without requiring predistortion calibration. Connected to a 2.4m diameter antenna, the remote modem performed carrier-echo-cancellation, enabling simultaneous use of the same bandwidth for both uplink and downlink with implementation loss lower than 0.01dB.

“NOVELSAT NS4TM waveform has proven to bring tremendous value to our customers and we are happy to demonstrate its outstanding performance over the advanced fully digital AMOS 17 satellite,” said Aviv Ronai, VP Marketing and Product at NOVELSAT. “Our technological superiority makes our satellite connectivity solutions the ideal, go-to-choice for service providers worldwide who are looking to efficiently support their most demanding applications.”

According to Amit Hoomash, Product Manager at Spacecom, “We were excited to demonstrate with NOVELSAT the very high throughput our customers can enjoy on AMOS-17, without having to compromise on solution complexity. The throughput and efficiencies of AMOS-17’s beams are unique over Sub Saharan Africa. NOVELSAT’S modems and team proved this, while using one modem per site and small antenna. Together with NOVELSAT, we are able to address important market segments with cost-effective, easy to deploy and maintain solutions.”
