While speaking with its customers, Advantech Wireless has noted that many need to make increasingly unpredictable demands on their network connections, particularly in the data capacity back from remote sites. While TDMA has long been seen as a solution to this, it is also known to be inefficient for streaming data flows.
A-SAT is beyond dual mode DVB-RCS/TDMA-SCPC, it monitors channel utilisation and switches the satellite access method and MODCOD for the return channel in real time to dynamically maximise the space segment utilisation efficiency. Additionally, by having TDMA and true DVB-S2 SCPC technologies in a single platform, the switch between traffic patterns is efficiently supported and all risks of equipment obsolescence are mitigated.
“We just love to innovate, and our A-SAT technology is a great example of that. We saw customers struggling to predict how to dimension their system in the face of constantly changing usage, so we solved it for them and optimised the efficiency,” explained Mark Lambert, VP Sales & Marketing, Managing Director, EMEA Region at Advantech Wireless.
During this demonstration Advantech Wireless is demonstrating multiple VOIP calls, a classic TDMA application, suddenly being joined by streaming. Visitors can see the VoIP calls being sustained as the Discovery Hub switches between TDMA and SCPC satellite access techniques to deliver maximum efficiency for the new situation.
