What is 5G?

� 5G is the next set of International Mobile Telephony (IMT) standards� These are specified by the 3GPP (3G Public Partnership), and then standardized by regional

regulators around the world

� ITU has described these as IMT-2020, outlining some categorizations as shown below:

5G requires seamless integration of heterogeneous e lements using innovative tools

5G is about Communication, Storage and Processing“anywhere-anytime ” for people & things , for a broad range of vertical markets, use cases and business models

To accomplish this, 5G must seamlessly integrate heterogeneous network elements (cellular, WiFi, satellite, fiber, legacy fixed networks, etc), leveraging innovative tools such as NFV, SDN, Multicasting, Cloud/Local Storage, etc.

Communication• Upload/download speed• Aggregate throughput

Storage• Cloud • Local / Device

Processing• Device power• Network capabilities

Satellite’s Roles in the 5G Ecosystem

� Ubiquity: Satellite provides high speed capacity across the globe using the following enablers: Capacity in-fill inside geographic gaps, overspill to satellite when terrestrial links are over capacity, general global wide coverage, backup / resilience for network fall-back and especially communication during emergency.

� Mobility: Satellite is the only readily available technology capable of providing connectivity anywhere outdoors on the move.

� Broadcast (Simultaneity): Satellite can efficiently deliver multimedia and other content across multiple sites simultaneously using broadcast and multicast with content caching for local distribution.

� The lead time to insert additions to the specifications is about 3 years, and takes many meetings

� Terrestrial mobile is ~2 orders of magnitude bigger than satcoms

� To be successful requires patience and collaboration; hence consortiums are helpful.

� The main consortium that SES are with is Sat5G

SaT5G Research Layers & Pillars

Research the key technology enablers for the integration of satellite in 5G

Contribute to standardisation of satcom as an intrinsic element of 5G

Build compelling business cases and commercial models

Build on current 5G research and contribute to the 5GPPP WGs

Validate and demonstrate solution in live testbeds

SaT5G - Satellite And Terrestrial network for 5G

� SaT5G Use Case 1: Edge delivery & offload for multi media content and MEC VNF software

• Providing efficient multicast/broadcast delivery to network edges for content such as live broadcasts, ad-hoc broadcast/multicast streams, group communications, MEC VNF update distribution.

� SaT5G Use Case 2: 5G Fixed backhaul• Broadband connectivity where it is difficult or not (yet) possible to deploy

terrestrial connections to towers, for example, maritime services, coverage on lakes, islands, mountains, rural areas, isolated areas or other areas that are best or only covered by satellites; across a wide geographic region

� SaT5G Use Case 3: 5G to premises• Connectivity complementing terrestrial networks, such as broadband

connectivity to home/office small cell in underserved areas in combination with terrestrial wireless or wireline

� SaT5G Use Case 4: 5G Moving platform backhaul• Broadband connectivity to platforms on the move, such as airplanes or

vessels

Focus of these Use Cases is Enhanced Mobile BroadBa nd (EMBB)

Some Final Remarks

It’s critical that Satellite face 5G intelligently

�5G development is agnostic about which mediums are used (as long as the particular use case performance requirements are met)

�Most 5G traffic does not require low latencies, so is satellite-compatible

�Since 5G aims to ubiquitously interconnect everything, satellite has an opportunity to be embedded into the world’s bigger comms system

• Satellite should pursue this opportunity seriously

�There are also very real 5G-led threats to satellite spectrum

• These must be dealt with separately from 5G standards participation

� Be proactive in 5G; Don’t wait for the world to come visit

• New partners, often bigger, will likely be needed

�Focused joint efforts are recommended
