![]() Non-coordinated spectrum sharing in a hybrid Terrestrial and Non-Terrestrial environment.ĭemos 1 and 2 use a detailed non-real time system/network level simulator developed for hybrid 5G TN and NTN network scenarios. Coordinated Dynamic Spectrum Access (DSA) in a hybrid Terrestrial and Non-Terrestrial environmentģ. Multi-connectivity for 5G Non-Terrestrial Networks (NTN) satellite scenarios,Ģ. The demonstration consists of three sub-demonstrations:ġ. ![]() LEO satellite system operating on S-band (around 2 GHz) frequency range providing services for handheld User Equipment (UE) was selected as a baseline for evaluations. Selected innovative technologies include Multiple-Input Multiple-Output (MIMO) schemes, multi-connectivity (MC) and coordinated/non-coordinated spectrum sharing between TN and NTN. ![]() DYNASAT project objective is to research, develop, and demonstrate the use of innovative techniques for bandwidth-efficient transmission and efficient spectrum usages for next generation satellite networks. NTN may for example complement terrestrial networks (TN) with network coverage in remote areas over sea and land where terrestrial coverage is absent. NTN topologies are based on high-altitude platforms and low Earth orbit (LEO) and geosynchronous orbit satellites. 3GPP is creating Release 17 specifications, which can also be used for SatCom systems, referred to as Non-Terrestrial Networks (NTN). Satellite Communication Systems (SatCom) are fundamental components supporting these goals. The European Commission’s “Connectivity for a Competitive Digital Single Market – Towards a European Gigabit Society” has set ambitious goals of deploying smart and sustainable networks and services for the success of Europe’s digital economy.
