abstract = {Industrial environments constitute a challenge in
terms of radio propagation due to the presence of machinery
and the mobility of the different agents, especially at mmWave
bands. This paper presents an experimental evaluation of a FR2
5G network deployed in an operational factory scenario at 26 GHz.
The experimental characterization, performed with autonomous
mobile robots that self-navigate the industrial lab, leads to the
analysis of the received power along the factory and the evaluation
of reference path gain models. The proposed assessment deeply
analyzes the physical layer of the communication network under
operational conditions. Thus, two different network configurations
are assessed by measuring the power received in the entire factory,
providing a comparison between deployments. Additionally, beam
management procedures, such as beam recovery, beam sweeping or
beam switching, are analyzed since they are crucial in environments
wheremobile agents are involved. They aim for a zero interruption
approach based on reliable communications. The results analysis
shows that beam recovery procedures can perform a beam
switching to an alternative serving beam with power losses of less
than 1.6 dB on average. Beam sweeping analysis demonstrates
the prevalence of the direct component in Line-of-Sight conditions
despite the strong scattering component and large-scale fading in
the environment.},
