ST1: Hybrid Terrestrial Satellite Networking and Services

Monday 5th September / Tuesday 6th September – 10:30, Room LLULL

Chairs: Constantinos B. Papadias (AIT, Greece), and Tinku Rasheed (CREATE-NET Research Center, Italy).

The continuously growing volume of mobile data, further assisted by the densification of base stations & access points places an increasingly heavy burden on the backhaul segment of the network. Leveraging the satellite segment as a way to relieve some of this burden is an approach that has been recently gained traction. For example, LTE/4G access served by satellite backhaul has been recently demonstrated, leading to a growing consensus that satellites should be part of the 5G networks. This vision is further exacerbated by the broadband and broadcast capabilities of satellites, as well as their wide area coverage that enables access at affordable cost and disaster resilience.

Based on the above, this proposed special track is focused around the concept of hybrid satellite / terrestrial networks that can serve jointly and in a better way the increasing backhauling needs of current, emerging and future mobile networks. Given the immaturity of the field, a number of key issues have yet to be explored, ranging from the required network architecture to the modelling of the involved channels (at 18GHz and 28 GHz) and interference, to the development of interference avoidance / mitigation techniques, possibly assisted by antenna arrays, to the definition of network virtualization and software defined networking for better end-to- end service provisioning.

The proposed special session is fueled by a number of recent results in two EU (H2020) research projects that are active in these research areas: SANSA (www.sansa-h2020.eu), which focuses on ensuring high capacity and resilience of these types of hybrid networks assisted by advanced antenna systems and VITAL (www.ict- vital.eu), which targets SDN- based, federated resource management for a unified control plane that would allow operators to efficiently manage and optimise the operation of hybrid SatCom- Terrestrial networks.

ST2: Ubiquitous Broadband Access

Monday 5th September – 14:00, Room LLULL

Chairs: Alberto Ginesi (ESA, The Netherlands), Ana Isabel Pérez-Neira (UPC, CTTC, Spain).

The satellite telecommunication market is currently living a technology revolution thanks to the success of High Throughput Satellites (HTS). The need for high speed interconnectivity everywhere on the planet is driving the satellite operators to very advanced technical solutions both at satellite and ground segment level. In particular, the need to provide a cost competitive high throughput connectivity to a wide geographical area with a typical large traffic spatial and temporal variability, is driving the system design to new paradigms in terms of flexibility of the resources as well as satellite design and production methods.

In this special track, some of these key aspects are presented by speakers representing some of the most successful and innovative satellite operators.

ST3: Applications and Technologies for Messaging and IoT/M2M over Satellite

Tuesday 6th September – 14:00, Room LLULL

Chairs: Stefano Cioni (ESA, The Netherlands). Sandro Scalise (German Aerospace Center (DLR), Germany).

The booming of applications in the areas of Internet of Things and Machine to Machine will play a prominent role in the upcoming development of 5G standard. Satellite telecommunication can play an important role whenever truly worldwide availability, even in very remote areas and across national borders is required.

Especially interesting are those applications scenarios where very large populations of terminals spread over large geographical areas need to sporadically transmit small amount of data.

In this special track, some of the most recent innovation technologies and developments are presented by speakers representing some of the most successful and innovative satellite operators and manufactures.
