Global satellite operator SES (Euronext Paris and Luxembourg Stock Exchange: SESG) and Newtec boost satellite efficiency in Africa. Mobile 3G networks in Africa are set to benefit from new-generation Newtec modems including, S2 Extensions technology that boost the performance and efficiency of the SES-5 satellite backhaul infrastructure.

SES has tested and implemented the Newtec MDM6000 Satellite Modems to increase the efficiency on its African SES-5 payload. The MDM6000 satellite modems are optimized for medium to high speed IP applications over satellite and are capable of delivering up to 37% in efficiency gains compared with the existing DVB-S2 standard, thanks to S2 Extensions. SES is one of the first satellite operators commercially using S2 Extensions.

The MDM6000 modems handle up to 380 Mbps bi-directionally. In this instance, the SES operated link transmits at 250 Mpbs over satellite, with the option to 'pay as they grow' in terms of demand.

"Fiber bridges the digital divide between the western world and Africa," says Ibrahima Guimba-Saidou, SVP for SES in 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."

Speaking about the project, Newtec's CEO Serge Van Herck comments: "I am pleased that by implementing our MDM6000 modems with S2 Extensions, SES and its customers are able to increase the amount of services within the same bandwidth, while reducing OPerational EXpenditure (OPEX) and increasing profitability. This is guaranteeing the best performance and optimal service availability for their 3G network."

S2 Extensions

The satellite industry reached a consensus on the fact that a successor to the DVB-S2 standard would be required to accommodate increased interoperability and growth in the satellite communications market. Newtec has taken the lead and teamed up with other DVB members to define and develop the updates on the DVB-S2 standard. When comparing the current DVB-S2 standard against the full implementation of S2 Extensions efficiency gains up to 37% can be achieved.

To learn what S2 Extensions are about and to get an insight when and how the industry will migrate to the more efficient transmission, Newtec is hosting an S2 info session including a panel discussion, at CommunicAsia 2013.
