Newtec's Flexacm boosts inclined orbit throughput and increases service availability for Skyvision
FlexACM provides IP throughput increase up to 137 % on inclined orbit satellite(PresseBox) ( St-Niklaas, )
SkyVision's point-to-point link between its teleport in Kenya and its main teleport in Austria uses an inclined orbit satellite. In order to follow the position of the inclined orbit satellite, SkyVision needs to use tracking on outbound and inbound antennas.
The Newtec FlexACM solution, that enables the usage of higher modulation schemes and lower error correction, results in an average data throughput of 74 Mbps, an 85 % improvement on performance from the previous system, and with peak-throughput speeds of 95 Mbps or 137 % during the best link conditions.
Mark Gazit President and CEO at SkyVision said: "Over the past eight years SkyVision has acquired a vast knowledge and experience with inclined orbit satellite solutions, allowing us to improve our services by collaborating with leading equipment manufacturers such as Newtec. Our partnership with Newtec has enabled better utilization of our space segment and significantly enhanced bit/hertz performance."
Newtec CEO Serge Van Herck said: "We are extremely happy that such a well respected service provider as SkyVision has recognised the benefits available from FlexACM. Not only does it compensate for rain fade or other link degradations, but also works effectively with satellites in inclined orbits, a property that was vital to SkyVision."
"Newtec is recognised as a company at the forefront of technological innovation, with expertise that we can pass onto our customers, helping them to fully achieve their business objectives, expanding their market reach and allowing them to reduce their operational expenses", concluded Van Herck.
Due to the movements of the inclined orbit satellite, the receiving site conditions are dropping with as much as 6dB, meaning that previously a lower modulation scheme and increased error correction (QPSK 2/3) had to be used, resulting in data throughput of only 40Mbps in a full transponder.
The implemented Newtec FlexACM solution, consisting of Elevation EL470 modems with on-board FlexACM client/controller, enables a higher modulation scheme and less error correction (up to 16APSK 4/5) whenever the situation allows, thereby giving higher throughputs up to 95 Mbps and guaranteed link availability.
In addition to using FlexACM for this Africa to Europe IP point-to-point inclined orbit link, SkyVision are also set to use FlexACM for their point-to-multipoint IP distribution network that shares a single outbound carrier. Each of the remote sites will receive their data within the carrier with optimised modulation scheme and error protection for each site. This will allow SkyVision to free up scarce C-band capacity and serve more customers within the same leased space segment.
SkyVision is a leading global telecommunication service provider. In today's fast growing telecom era, SkyVision's goal is to provide the best IP connectivity services in emerging Internet markets. SkyVision provides custom-tailored solutions to ISPs, enterprises and NGOs, and maintains an active presence in over fifty countries worldwide. SkyVision provides end-to-end solutions, deploying standard and customized IP service platforms managed from its international gateways.
