5G Standalone network

A full 5G SA architecture on the Hi5 platform, measured and put to use

Context

On the Hi5 platform, I analysed a full 5G Standalone (SA) architecture: a gNodeB, a 5G core and a dedicated optical fibre.

Beyond the analysis, the network carried two applications: real-time IoT geolocation and mobile video surveillance.

Architecture

From the radio to the 5G core, and on to the applications

Devices connect over 5G radio to the gNodeB, linked to the 5G core by a dedicated optical fibre. Throughput and latency were measured depending on the network topology. IoT positions reach Node-RED over MQTT for real-time geolocation, and a mobile video-surveillance application runs over 5G.

What I did

  • Analysed the full 5G SA architecture: gNodeB, 5G core and dedicated optical fibre.
  • Measured throughput and latency depending on the network topology.
  • Built a real-time IoT geolocation system with MQTT and Node-RED.
  • Connected a mobile video-surveillance application over 5G.
