Sint-Niklaas, Belgium, 28th January 2010. Newtec announced today that its unique award winning FlexACM technology – which on average doubles satellite link capacity – is the system behind Gateway Communications’ flagship continent-wide internet backbone service, Africa IPJetDirect.

Gateway Communications, which has the largest pan-African communications network with customers in 40 countries, successfully launched IPJetDirect last year using C band and Ku band satellites to deliver IP services to mobile phone operators in Africa. Newtec’s DVB-S2 VCM and DVB-S2 FlexACM technologies have been deployed on several platforms across the African continent to ensure maximum bandwidth efficiency and allow Gateway to make best use of the scarce satellite capacity over Africa.


“Gateway has always been a pioneer of high quality, cost effective voice and data connectivity across Africa. By using FlexACM it can now reach out even further to satisfy Internet demand – and without unnecessary further satellite capacity investment,” said Newtec CEO Serge Van Herck. “FlexACM’s unique ability to dynamically optimize an end-to-end satellite transmission is ideal in this situation and we are delighted to be playing a part in supporting Gateway’s drive to deliver truly world class communications solutions across Africa”, Herck added.

FlexACM combines a range of cutting edge technologies for implementing Adaptive Coding and Modulation (ACM), traffic shaping, payload compression and IP acceleration in a highly efficient way for IP trunking and IP backbone satellite links. In addition to doubling the capacity of an existing link, on average, it also guarantees 100 per cent availability of link reception, even when all other systems are down due to heavy rain fade. FlexACM can be used in point-to-point and point-to-multipoint systems, in one way (with terrestrial return channels) as well as two way configurations (with the return channel also over satellite). It can be used to upgrade existing satellite links without changing other elements of the transmission chain, such as the antenna or HPA.

“Newtec’s technology gives us a highly efficient method of delivering large quantities of data into small antennas and the Variable Coding and Modulation (VCM) functionality allows the same platform to address many different sized antennas in the same footprint,” explained Gateway CTO Chris Young.

“FlexACM is optimising the transmission dynamically and automatically. It is helping us in our drive towards easy and cost-effective Internet access and to make sure Africa leads the way global communications are moving”.

FlexACM is available on Newtec’s Elevation product family, which consists of DVB-S2 IP Satellite Modulators, Demodulators, Modems and Satellite IP appliances.
