▪ Supply Dominated by GEO Satellites in Ku/Ka> Significant increase in HTS spot beam
technology > Provides ~ 90% of overall 2,400 Gbps of
capacity > Challenges at higher latitudes & poles
▪ Typical Real World Speeds to Aircraft of 20 – 50 Mbps
▪ Costs as high as 3-5 cents per MB
▪ Passenger Throughput of 2-3 Mbps Seen on HTS Systems
▪ Traffic Shaping and Fair Use Policies in Place to Limit Consumption
▪ Consistent Performance Still a Challenge Across Providers
▪ New service provider will contribute to drive the price down

▪ Software-Defined Networking (SDN) leverages on the
concept of user and control plane separation in packet
switched networks
▪ SDN is based on the concept of ‘flow’: a fundamental
rethinking of the wireless and wired connectivity fabric
▪ Typical SDN Network services> Load balance algorithms
> Traffic steering
> Path computation
> Security management
▪ NFV makes use of SDN to create complex
network functions chaining

▪ Satellite backhaul bandwidth is still a limitation for aircraft
connectivity > HTS constellations can improve the situation
> Traditional connectivity is with GEO but other constellations become appealing
▪ Emulated lab set-up> GEO path with virtualized Sky Edge II-c
> 5G paradigms for satcom integration
▪ High-fly demonstration> MEO path using O3b constellation
> Hopefully precursor of true multi-satellite connectivity
▪ We target satcom in the Ka-band

and low-noise block downcoverter (LND) units
▪ The antenna is integrated with a MEO booster to facilitate
tracking the O3b satellites
▪ The antenna will be integrated with the Gilat modem
▪ The system will be configured in SCPC mode
▪ The SPI test-bed shall ensure to enable seamless satellite
handoff in the MEO constellation
