Shared Access Satellite-Terrestrial Reconfigurable Backhaul Network Enabled by Smart Antennas at MmWave Band

5G traffic expectations require not only the appropriate access infrastructure, but also the corresponding backhaul infrastructure to ensure well-balanced network scaling. Optical fiber and terrestrial wireless backhaul will hardly meet 100 percent coverage, and satellite must be considered within the 5G infrastructure to boost ubiquitous and reliable network utilization. This work presents the main outcomes of the SANSA project, which proposes a novel solution that overcomes the limitations of the traditional fixed backhaul. It is based on a dynamic integrated satellite- terrestrial backhaul network operating on the mmWave band. Its key principles are seamless integration of the satellite segment into terrestrial backhaul networks, a terrestrial wireless network capable of reconfiguring its topology according to traffic demands, and aggressive frequency reuse within the terrestrial segment and between terrestrial and satellite segments. The two technological enablers of SANSA are smart antenna techniques at mmWave and software defined intelligent hybrid network management.

SANSA - Hybrid Terrestrial-Satellite Backhaul Network: Scenarios, Use cases, KPIs, Architecture, Network and Physical Layer Techniques

SANSA (Shared Access terrestrial-satellite backhaul Network enabled by Smart Antennas) is a project funded by the EU under the H2020 program. The main aim of SANSA is to boost the performance of mobile wireless backhaul networks in terms of capacity, energy efficiency and resilience against link failure or congestion while easing the deployment in both rural and urban areas and assuring at the same time an efficient use of the spectrum. This paper provides an overview and the first results of the project and, more specifically, it describes the regulatory environment, the State of The Art of mobile backhauling technologies regarding Ka band, the scenarios, the use cases, and the KPIs along with the SANSA architecture, network (NET), and physical (PHY) layer techniques used to enhance wireless backhauling capabilities

Internet of Things at Sea: Using AIS and VHF over Satellite in Remote Areas

This paper describes how the Automatic Identification System - Application Specific Message (AIS/ASM) via Low Earth Orbit (LEO) satellites can be used to transmit small data between ship and shore to facilitate information visibility in future maritime transport systems. The focus is on ships without advanced satellite terminals in remote areas where terrestrial infrastructure is not available. Here, AIS is proposed as a low cost and general alternative to ordinary satellite communications. In this paper, we report on how reliable ASM is for data exchange, for instance for cargo-monitoring data. One problem is to determine when the LEO satellite is in a geographic position to receive messages from the ship. Another problem is that the AIS satellite can fail to register data, even when in the radio range of the ship, because the ship antenna is constructed for horizontal radiation and sends very little signal upwards, especially when the satellite is at its closest to the ship. The study uses AIS data from the Norwegian Coastal Administration to determine the probability that specific AIS transmitters are detected by the satellites

Terrestrial-satellite integration in dynamic 5G backhaul networks

This paper presents a dynamic backhaul network in order to face some of the main 5G challenges such as 100% coverage, improved capacity or reduction in energy consumption. The proposed solution, elaborated within the SANSA H2020 project, is based on the seamless integration of the satellite component in a terrestrial network capable of reconfiguring its topology according to the traffic demands. The paper highlights the benefits of this hybrid network and describes the technology enablers to bring it to the reality. Finally, the SANSA's network simulation framework based on ns3 is presented, jointly with a preliminary analysis of the routing and load balancing needs for a hybrid and dynamic network.Peer ReviewedPostprint (published version
