Architecture

The foundation of the NexaSphere Network Architecture is based on 3GPP specifications, i.e., a User Equipment (UE) connects to a 5G base station (gNB) which is served by a 5G Core (5GC). External services are accessed via Data Networks (DN) that connect to the 5GC.

UEs can connect directly or via Customer Premise Equipment (CPE). The CPE is a sub-system on-board an airplane or train providing connectivity and other functions to passengers, e.g. via WiFi, LiFi or 3GPP in a relay mode. The CPE can be backhauled by Non-Terrestrial Networks (NTNs) and Terrestrial Networks (TNs). Also for direct connections of the UE, NTNs and TNs can be used. A multi-connectivity sub-system enables the simultaneous or selective use of multiple access technologies. Antenna systems are required for the wireless links support, associated with the access technologies.

The Edge-cloud continuum provides distributed processing, storage and advanced service capabilities including the hosting of network functions. It consists of edge cluster and cloud nodes, deployed along the communication path, complemented by a management and orchestration (MANO) system, Artificial Intelligence (AI) resource management functions and a compound AI system supporting intelligent end-to-end operation
