Recent Important Observations in MSS: • L-band about to be saturated with MSS traffic • Higher MSS traffic volumes foreseen in the future • MSS Traffic more packet data oriented – Internet Protocol (IP) • MSS traffic tends to be highly asymmetrical • Services requiring significantly higher capacity on the satellite link become more common and significant Consequences: • Significantly more spectrum is required in the future – L-band too restricted for future growth • Must utilise C-band, K u -band, and K a -band to support future growth in MSS
Major Challenges for bringing MSS above L-band: • Regulatory issues • Expensive technology development Technology • Short term approach: • System solution combining Inmarsat technologies and DVB technologies • DVB-S/MPDS hybrid systems • DVB-S2/BGAN hybrid systems • Longer term approach: • Develop new standard, preferably open, for MSS above L-band • Enhancement of DVB-RCS towards supporting MSS • Reuse elements from Inmarsat technologies • Optimal adaptation of technology to mobile channels gaining cost-efficiency • Channel adapted multiplexing of data streams for packet data transmissions • Adaptive coding and modulation
