Private 5G · Research & teaching

A mobile lab for private 5G.

5G on Wheels combines real radio hardware, an open-source core and an integrated observability environment into a research platform at RheinMain University of Applied Sciences.

The goal: a mobile laboratory on a wagon. Today, the antenna uses a tripod and the small cell connects to a stationary campus core.

Wagon concept
From setup to mobile lab

Working today. Designed to go further.

The mobile platform grows out of the thesis implementation. Its network and its mechanical concept are at different stages.

In operation

Current setup

SC-418, tripod-mounted antenna, campus Open5GS core and instrumented test devices. Direct Ethernet and a separate router-backed path have been exercised.

Concept

The wagon goal

A shared rolling base, adjustable crank mast, upright small-cell mounting and organised power and cabling.

Next steps

Next validation

Build the wagon with an adjustable mast and test deployment at multiple prepared sites. Use repeatable experiments to compare backhaul and application behaviour.

Research, teaching, applications

More than a connected phone.

Use the platform to ask a question and observe the answer across the network.

01

Understand 5G in a lab

Follow registration, authentication and PDU-session setup using actual devices and core events.

02

Run comparable experiments

Measure an end-to-end path and relate its behaviour to device, backhaul and workload.

03

Connect campus sensing

The campus weather station sends sensor data through the RUT976 and private 5G network to the existing application.

Architecture

From device to campus service.

The radio site is relocatable. Signalling and user traffic reach the stationary core over a campus backhaul connection.

What would you explore with a private 5G network?

Connect new devices, try different backhaul paths or develop an application for the campus. The platform is a starting point for the next project.
