Hi everyone,
I am new to the 5G campus network research and I wonder what your experience with the performance of 5G campus networks are (5G Standalone)? I know it depends on the settings, configurations, hardware etc.
Background of this question is, are the advertised numbers (Up to 1Gbit/s Up- and Download, latency of lower than 5ms) reality?
F.e. the following paper shows UL-rates on average up to 740 Mbit/s DL, 126 Mbit/s UL, 8MS on outdoor performance. https://www.hs-osnabrueck.de/fileadmin/HSOS/Forschung/Recherche/Laboreinrichtungen_und_Versuchsbetriebe/Labor_fuer_Hochfrequenztechnik_und_Mobilkommunikation/Mobilkomtagung/2022/Vortraege/18_Mallikarjun.pdf
On the other hand another paper with the same Core shows only UL-rates up to 20 Mbit/s? https://www.mecsware.com/uploads/7/4/5/3/74536059/komma2020_private_small_cell_in_sf.pdf
Some insights would be really helpful.
Best regards

The performance of 5G campus networks, especially in a standalone (SA) configuration, can vary widely depending on various factors, including settings, configurations, hardware, deployment environment, and network design. Achieving the advertised numbers of up to 1 Gbit/s in both uplink and downlink with latency below 5ms is theoretically possible under ideal conditions, but it's not always a reality in real-world deployments. Here are some insights into why you might see variations in performance:
1. Deployment Environment: The physical environment in which the network is deployed can significantly affect performance. Factors like interference, signal propagation, and obstacles can impact signal quality and, consequently, data rates.
2. Network Configuration: The configuration of the 5G network, including the choice of frequency bands, spectrum allocation, and antenna placement, can influence performance. Some frequencies offer higher bandwidth but shorter range, while others provide better coverage.
3. Network Load: Network performance can vary depending on the number of connected devices and the data traffic they generate. High network congestion can lead to reduced data rates.
4. Hardware and Infrastructure: The quality of the network infrastructure, including base stations and user equipment, can impact performance. High-end equipment may achieve better speeds than lower-end alternatives.
5. Application and Use Case: The specific use case and applications running on the network can affect performance requirements. Some applications may be more sensitive to latency and require higher data rates than others.
6. Research Methodology: When interpreting research papers, it's essential to consider the methodology used in the experiments. Factors such as the number of test scenarios, equipment used, and environmental conditions can lead to variations in reported results.
7. Time and Evolution: The performance of 5G networks can improve over time as operators optimize their networks and roll out software updates. Early deployments may not reach the same performance levels as mature deployments.
Given these factors, it's not surprising to see variations in the reported performance of 5G campus networks. It's essential to consider the context and conditions under which the measurements were taken when evaluating research papers. Additionally, performance may vary from one campus network to another based on specific deployment choices and objectives.
If you're working on 5G campus network research, conducting your own field tests and measurements in your specific deployment scenario can provide valuable insights into the network's performance and help validate or refine the published results.
