SatLink Communications, and NovelSat, high-end manufacturer and developer of the groundbreaking 3G-Sat modulation technology, NS3™, announced today they have completed a live trial of NovelSat’s Modulator (NS1000) and Demodulator (NS2000), which incorporates NS3™ technology. The results of the trial have shown increases of over 50% in bandwidth efficiency when compared to DVB-S2.
SatLink tested NovelSat’s NS3™ enabled devices against the industry’s best DVB-S2 modulators and demodulators, under a typical video contribution setting. The meticulous comparison was conducted over the AsiaSat5 and Eutelsat W3A Satellites, while maintaining an identical link budget and fade margins. Throughout the test regiment, NS3™ demonstrated a spectral efficiency improvement over DVB-S2 resulting in a 28% capacity boost over a 36MHz transponder at a typical broadcasting operation point of CNR of 7 - 8 dB.
When SatLink ran the NS3™ enabled gear over a 72MHz transponder, the results exceeded the 50% improvement mark – particularly remarkable given the inherent limitations on receivers currently available. Presently, 72MHz transponders are mandatorily divided into two carriers with 20% guard band to avoid co-channel interference due to this demodulator handling limitation. This limitation dramatically reduces the efficiency of 72MHz transponders. The NS2000 Demodulator from NovelSat is the first demodulator capable of consolidating these two carriers into a single 72MHz carrier that can now be saturated. 358Mbps throughput was also measured over the 72MHz transponder.
“SatLink serves some of the largest broadcasters around the world. We are constantly looking for the most advanced technologies to add value to our services, which is why NovelSat’s NS3™ Modulation solution really intrigued us,” said David Hochner, CEO of SatLink Communications. “The results of our live trial with NS3™ are extremely promising and would present a great value to our broadcast, data, and government customer base.”
“NovelSat’s relationship with SatLink over the past three years has been a fruitful one. SatLink has provided NovelSat with valuable market support and insight,” said Itzik Wulkan, CEO of NovelSat. “This meticulously managed trial by a professional teleport such as Satlink, has proven and supported our claims for the unmatched performance of our entire line of NS3™ enabled devices. We are confident that this will significantly help SatLink continue to be leaders in satellite video broadcasting as the entire industry faces the challenge of increased bandwidth demands, cost, and decreased satellite space.”
