▪ Wireless connectivity is gaining momentum for airports and airlines

▪ The aviation industry is awaiting 5G to enable innovative services, harmonize the needs of aviation through impactful standardization and regulatory activities

The aviation sector at a glance




▪ 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

▪ Use Case 2: 5G Fixed Backhaul > Satellite backhaul to groups of cell towers> Satellite backhaul to individual cell towers> satellite backhaul to individual small cells

▪ Use Case 3: 5G to premises> Hybrid Multiplay (satellite/xDSL) at home/office premises in underserved areas> Hybrid Multiplay (satellite/cellular) at home/office premises in underserved areas

▪ Use Case 4: 5G Moving platform backhaul> Updating content for on-board systems and grouped media request by the moving platform

company> Broadband access for passengers and individual media requests> Business and technical data transfer for the moving platform company

Orchestration Methods




ETSI MANO Architecture




▪ 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

▪ Multicast over satellite> Simultaneous distribution of IFE content to multiple airplanes

▪ Multi-catalogue IFE system> PAX access additional content cached on-board

> Connectivity over mobile network technology (4G/5G)

> Traditional IFE content distributed to wireless seat screens over WiFi

▪ Mobility management> Handover of passengers‘ user plane traffic

SPI test-bed use cases




▪ Unified 5G management system> Convergence of satellite and mobile technologies

▪ 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
