[Satellite TODAY 09-09-11] Satellite transmission services provider SatLink Communications has completed a live trial of NovelSat’s 3G-Sat NS3 modulator (NS1000) and demodulator (NS2000) technology, which resulted in more than 50 percent increases in bandwidth efficiency when compared with the DVB-S2 standard, SatLink announced Sept. 8.
SatLink tested NovelSat’s NS3-enabled devices against 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 to 8 decibels. When we ran the NS3-enabled gear over a 72MHz transponder, the results exceeded the 50 percent improvement mark.” SatLink said in a company statement.
NovelSat released its NS3 modulation technology in July. NovelSat CEO Itzik Wulkan said he was pleased to receive the results from a professional teleport, and hopes the test proves and supports the company’s claims that NS3-enabled devices can help broadcast companies deal with, “increased bandwidth demands, cost and decreased satellite space.”
