SatLink Communications + NovelSat… Bandwidth Efficacy Betterment (SATCOM)

[SatNews] Incorporating new technology, the Company has completed a live trail that resulted in impressive efficiencies…

SatLink Communications, a provider of global satellite transmission services, and NovelSat, high-end manufacturer and developer of the 3G-Sat modulation technology, NS3™, 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 more 50 percent 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 percent 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 percent improvement mark – particularly remarkable given the inherent limitations on receivers currently available. Presently, 72MHz transponders are mandatorily divided into two carriers with 20 percent 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.
