Analysis of Open RAN Performance Indicators Related to Holographic Telepresence Communications

This paper presents experimental work related to the performance measurement of throughput, delay, and delay jitter as key performance indicators (KPIs) for the realization of high-quality holographic telepresence applications. The communication scenario assumes a wireless Radio Access Network (RAN) based on an Open-RAN architecture. For the experiments an LTE testbed based on an open-source platform is used integrating the open RAN architecture with two types of functional splits and an Evolved Packet Core (EPC) deployed on the top of standard Linux based machines. The KPIs are evaluated both in the downlink and uplink in the cases of the different split scenarios.
