MAINDATA 2-way Broadband Satellite Internet Platform
Key DVB RCS features:
Low cost & High Performance solution60 Mbps in a forward channel !!!2 Mbps in a return channel per terminal !!!2-way terminals for prices < 2.000 €
Efficient satellite capacity usage (30-70 % savings)While forward channel deploys ordinary DVB-S transmission return channel RCS deploys enhanced MF-TDMA access scheme as well as Turbo-coding significantly increasing efficiency of satellite
segment usage.
Open standard systemDVB RCS is a first Open Standard system for 2-way satellite system.In opposite to proprietary systems provides high flexibility to Service Operator, for example by a change choose HUB and terminals from different vendors. As always standards leads to quick reduction in pricing as experienced with DVB-S system in past 4 years.
