I need to conduct measurements to assess the performance of 5G NSA networks, as 5G SA is not yet deployed in France. My study involves comparing 5G NSA and 4G networks using two separate user equipments, one for each network. My concern is about inter-RAT handovers. How can I fairly compare these networks when, for instance, the 5G mobile switches to 4G during an inter-RAT handover? Should I continue to account for the performance of this equipment even when it is connected to 4G? Additionally, I've noticed that the frequency bands used by both networks are often similar, especially in the lower bands. How can I then conduct a fair comparison between the two networks
Conducting a fair comparison between 5G-NSA and 4G deployments in specific areas of France requires careful design and consideration to ensure accurate and meaningful results. Here's a breakdown of key steps:
Define your area of comparison:
- Choose representative areas in France with varying population densities, urban/rural landscapes, and existing network infrastructure. Consider areas covered by both 5G-NSA and 4G to enable direct comparison.
Select relevant metrics:
- Throughput: Measures data transfer speed, crucial for tasks like downloading/uploading files and streaming media.
- Latency: Represents the time taken for data to travel between devices, critical for real-time applications like video conferencing and online gaming.
- Jitter: Variation in latency, impacting video/audio call quality and online gaming experience.
- Coverage: The area covered by the network signal, ensuring a fair comparison where both technologies have similar reach.
Design your testing methodology:
- Standardized testing tools: Use consistent tools and methodologies across locations to eliminate device-specific biases.
- Multiple data points: Collect data from various locations within each chosen area to capture overall network performance, not just isolated cases.
- Controlled environment: If possible, conduct tests during low network traffic hours to minimize external interference.
Data collection and analysis:
- Record data: Gather throughput, latency, jitter, and coverage measurements for both 5G-NSA and 4G at each location.
- Statistical analysis: Utilize statistical techniques like mean, median, standard deviation to analyze collected data and identify statistically significant differences between technologies.
- Visualization: Present your findings through graphs, charts, and tables to clearly convey performance comparisons.
Additional considerations:
- Network operator variations: Account for potential differences in network configurations and optimization strategies between different mobile operators in France.
- Device compatibility: Ensure test devices are compatible with both 5G-NSA and 4G networks for accurate comparisons.
- Repeatability: Consider replicating your testing methodology to validate results and increase confidence in your findings.
By following these steps and carefully addressing potential biases, you can conduct a fair and informative comparison between 5G-NSA and 4G deployments in selected areas of France. Remember, the specific details of your testing methodology will depend on your research goals and available resources.
