| Advantech Satellite Networks Demonstrates First DVB-S2 Ka Band Two-Way System
Advantech Satellite Networks, in collaboration with Telesat Canada and the Canadian Space Agency (CSA), has demonstrated the first use of DVB-S2 in a DVB-RCS system with a satellite operating at Ka band. The demonstration was on Telesat''s Anik F2 satellite with spot beams. The demonstration used Advantech Satellite Networks'' latest DVB-S2 hub and terminal products, based on the DVB-RCS open standard and Advantech AMT’s DVB-S2 modulator. The demonstration highlighted high speed internet access for Northern communities in Canada. As compared to the existing DVB-S technology, DVB-S2 allows significantly reduced satellite bandwidth usage for a given data throughput. This translates into reduced operating costs for DVB-RCS customers. David Gelerman, CEO of Advantech AMT, said: “The Canadian government’s early adoption of DVB-RCS technology using the key Anik F2 Canadian satellite asset is enabling a leadership role in satellite solutions delivery to remote populations of Canada. It is the culmination of many years of work started by the Canadian government in 1990 in partnership with Advantech and Telesat. With Anik F2’s Ka-Band payload, we will be pioneering ACM (Adaptive Coding & Modulation) based solutions.” “Ka band has played, and will continue to play, an important role in our overall DVB-RCS product strategy,” explained Don Osborne, President of Advantech Satellite Networks. He went on to say: “Our first hub was deployed in Ka band in 2000, and we have delivered over 1,000 terminals to operate in Ka band. The major advantage of Ka band from the stand-point of the end user is lower service pricing. Lower service pricing is possible as a result of spot beams and frequency re-use in Ka band satellite design.” |
