Multigigabit Extremely High Throughput Terminal
Satellite-based broadband telecommunications are currently experiencing an unprecedented boost in terms of technology innovations and performance. A number of very innovative and efficient VHTS (Very High Throughput Systems) have been recently announced with the capability to deliver in the order of one terabit/s total user link throughput both via GEO or LEO orbits. It is foreseen that, following the increasing user needs of high speed connectivity, the next generation VHTS (EHTS – Extremely High Throughput Systems) will be able to deliver tens of terabit/s throughput and user peak rates of multi Gbps. Throughputs in the order of 10-15 Gbps are required by large cruise ships within the next 4-5 years. This is in principle possible by exploiting the full 3 GHz of the Ka-band as well as the highest spectral efficiency modes supported in state-of-the-art air interfaces like DVB-S2X.
MEHTT will start with an analysis of the requirements of a user terminal operating in Ka-band in future EHTS systems. Given the target throughput, the application scenarios are related to internet access of passenger entertainment of large mobile platforms (ships and airplanes).
MEHTT is a project funded by ESA (Contract ESA AO/1-10001/19/NL/FE) and RedCat Devices is in charge in the implementation of the chip in a CMOS process below 65nm.
