S2 Extensions Technology from Newtec Increases SES-5 Satellite Performance
By Frank Griffin, TMCnet Contributing Writer
Satellite technology has introduced information and communication technology (ICT) to the most remote locations around the world. This gives developing nations with limited or nonexistent infrastructure the ability to implement mobile communications and Internet services to all of their citizens.
Rural areas in developing areas have limited access to technology even with satellites. To boost the performance and efficiency of the SES (News - Alert)-5 satellite backhaul infrastructure, SES has implemented the Newtec MDM6000 Satellite Modems.
This modem will increase the efficiency on the payload of the SES-5 satellite and increase the performance of backhaul infrastructure in Africa. The modem was tested and optimized for medium to high speed IP applications over satellite. Compared to existing DVB-S2 standards, the new S2 extension delivers efficiency gains of up to 37 percent.
The new S2 extensions improvements give professional applications smaller roll-offs, advanced filtering, support different network configurations, increased granularity in MODCODs, higher modulation schemes up to 64 APSK, linear and non-linear MODCODs and wideband support up to 72 Mbaud.
SES operates a global fleet of 53 geostationary satellites and the connected network of teleports. The African continent is covered by nine of the satellites and they provide ICT services for businesses and government organizations throughout the continent including mobile and fixed network operators, broadcasters, and content and Internet service providers.
"Fiber bridges the digital divide between the western world and Africa, but does not bridge the digital divide within Africa between urban and non-urban areas. This new technology boosts the performance of satellite power which transcends geographic challenges to provide that vital last mile connectivity in Africa," said Ibrahima Guimba-Saidou, SVP for SES in Africa.
The SES link is able to transmit at 250 Mpbs over satellite with different options in terms of demand, but the NDM6000 modems can handle up to 380 Mbps bi-directionally.
The goal of this project is to provide the African mobile 3G networks more reliability not only in urban areas, but also rural communities that are increasingly becoming dependent on this technology.
Newtec is a recognized global leader in satellite communications by offering state-of-the-art technology with strong R&D development for broadcast, broadband access, and backbone and trunking applications.
