Advantech Wireless, a Canadian-based manufacturer of broadcast-quality Satellite, RF Equipment and Microwave Systems announces the release of the newest generation satellite communications product, the Discovery Series A-SAT Product line. A-SAT stands for Adaptive Satellite Access Technology. A-SAT is beyond dual mode RCS/TDMA-SCPC, developed by Advantech several years ago and well ahead of the competition that just announced basic versions of this capability. A-SAT monitors channel utilization and switch seamlessly the satellite access method and mod code for the return channel to dynamically maximize the space segment utilization efficiency.
Advantech Wireless Inc., is a technology power house, having developed over the years both High Throughput SCPC Modems, and DVBS2/RCS-TDMA Discovery Hubs. The lower cost of the Entry Level Discovery 100 Hub, which features the high throughput AMT-75 modem with embedded IPE, has allowed Advantech Wireless to offer similar throughput (100 Mbps+) as the Hub forward link right at the remote stations. It is like having a Hub outbound capability at the remote station with Demand Assigned Multiple Access (DAMA).
More importantly, it does it in a way that significantly saves space segment by using dynamic DVB-S2 and modcodes all the way to 16 APSK LDPC (or even 32APSK, if the link could be closed) on the return channel and the fastest TDMA-RCS scheduler in the world featuring 26.5ms frames.
Operators often face the dilemma of choosing between SCPC or TDMA platforms depending on their customer’s applications and traffic patterns, and more recently face the problem of limited throughput VSATs, as their customer application now demand more and more bandwidth on the return channel. Recognizing the dynamic nature of traffic and unpredictable traffic bursts, A-SAT technology developed by Advantech Wireless resolves this dilemma by combining both technologies in the same platform which adapts to the traffic needs, seamlessly to the user, and delivering the best navigation experience with the lowest occupied transponder bandwidth.
Having both technologies in the same platform significantly saves OPEX and SIMPLIFIES the operation, eliminating the cumbersomeness of handling multiple, often divorced platforms. Supporting from tens to tens thousands of users, the Discovery Series Hubs and remote terminals offer software key upgrade solutions to grow and meet any need.
