Satellite - Technology Enabler for Advanced Wireless Networks

WINLAB Fall/Winter 2016 Research Review

Challenges For Advanced Wireless Networks

• Higher speed access network
• Higher capacity density
• Higher capacity core/backhaul network
• Shifting traffic patterns
• New applications with stringent connectivity requirements (e.g. IoT & latency)
• Video consumption trends
• Evolving architecture – cloud, edge cloud, virtualization of functions

Integration of distinct networking technologies

Capacity & Connectivity

Flexible network architecture and topology Scalable infrastructure designed for growth Available where and when needed Efficient capacity allocation

Sweet spots for satellite-based networks

Data communications via HTS satellites will increase in efficiency by a factor of

10x

High Throughput Satellites

2x frequency reuse through dual polarization Increased frequency reuse through spot beam & dual polarization

Upcoming Geosynchronous HTS Satellites

HTS

Scalable Smaller antennas* for same link throughput Higher efficiency modems Lower costs per Mbps Higher throughput Served by the Mbps

• r MHz

Meeting demand: The Critical Role of HTS as an Enabler

O3b Medium Earth Orbit Constellation

1.6 Gbps/beam 8064 km altitude - ¼ latency of GEO

Satellite Sector Investments High Throughput Satellites (HTS) Driving Innovation

Operator investments in HTS satellites is driving unit bandwidth costs down.

…enabling lower unit bandwidth costs

Satellites within the Global Communications Infrastructure

Satellites already form a ubiquitous part of the global communications infrastructure

SES & WINLAB Satellite CDN Overlay Demonstrator

• Hybrid terrestrial-satellite network architecture.
• Combines satellite’s wide coverage areas, ubiquitous

access, and broadcast-ability with intelligent routing, caching, and popularity metrics.

• Satellite solutions with greater network awareness

and intelligence are needed to differentiate our service offerings in the marketplace. Key Characteristics:

• Efficiency:

satellite multicast replaces terrestrial unicast, content caching

• Awareness:

traffic demand, content popularity

• Intelligence:

intelligent traffic routing, data driven cache management

• Performance:

edge storage improves experience – lower latency, higher QoS
