Is HTS a Disruptive Technology?Changing the metrics of the satellite industry
Mbps versus MHzFill-rate – what is the valid measurement?End-to-end solutions Packaged solutions rather than bespoke solutions
Potential to cannibalise existing FSS revenuesViaSat-3 constellation = 2 x total capacity of existing GEO
fleetImpact on service providers and teleport operators
Defined gateway locationsOperator build out of unified networkLimited opportunities for third party teleport operators

HTS System DesignTotal System Throughput is determined by:
Modulation Efficiency
Available Bandwidth
Frequency Re-use
![Page 18: Session 2 3 david ball consultant](https://reader035.vdocument.in/reader035/viewer/2022062522/5872ce481a28ab74188b482f/html5/thumbnails/18.jpg)

HTS System DesignImproving Total System Throughput:
Modulation Efficiency Gains are limited by channel non-linearity
Available Bandwidth Reduce colour count – wider transponder BW Expansion into non-standard bands, new frequency
bandsFrequency Re-use
Narrower beams, increased spotbeam count, increased frequency re-use

Future HTS Developments – Efficiency Drivers / GoalsIncrease Overall Throughput
Modulation efficiencyUse of new frequency bands for feeder links
Need to consider spectrum licensing and availabilityReduce Cost per Bit
Space segment cost – improve efficiencyGateway efficiency – throughput / number of gatewaysReduce cost of user equipment / antennas / installation
Flexible ArchitectureRespond to changing market demandsIncreased deployment of processing payloads

Future HTS Developments – Additional SpectrumUse additional feeder link spectrum
Q band Space-to-earth 37.5 – 42.5 GHz
V band Earth-to-space 47.2-51.4 GHz
W band Space-to-earth 71-76 GHz Earth-to-space 81-86 GHz
Most ITU filings already include Q and V bandThe race for spectrum has begun early
Equipment availability limited at this time
