# Compatibility Analysis Between RedCap Non-Public Networks and 5G NR in TDD FR1 and FR2 Bands
## 7 Results of the Studies  
This study's findings are presented in terms of signal-to-interference-plus-noise ratio levels for both the downlink and uplink channels of the affected 5G NR network. Average throughput calculations are provided both before and after interference, offering insights into the performance impact on the victim 5G NR network. These results enable the estimation of an average throughput loss for 5G NR networks when RedCap is integrated into private networks for urban deployment. The percentage of throughput loss in this study was derived by comparing the throughput values of the 5G NR network before and after interference from RedCap devices. These values were obtained using simulated curves of throughput versus signal-to-interference-plus-noise ratio (SINR) generated for both the uplink and downlink scenarios.  
The percentage loss was computed as the difference between the baseline (pre-interference) throughput and the degraded (post-interference) throughput, expressed as a percentage of the baseline.  
This approach enabled the quantification of throughput loss for different scenarios, including the uplink and downlink directions and FR1 and FR2 frequency bands, providing a detailed assessment of interference impact.  
In Figure 6, the SINR levels and throughput loss of the downlink channels in the FR1 band are illustrated.  
In scenarios where RedCap is deployed in the FR1 band, the average throughput loss of the downlink channel for public 5G NR networks is calculated to be 4.5%. While this is in proximity to the threshold level, it remains within an acceptable range of throughput loss.  
Figure 7 depicts the SINR levels and throughput loss for the uplink channels of the 5G NR victim network in the FR1 band.  
In scenarios where RedCap is deployed in the FR1 band, the average throughput loss of the uplink channel for public 5G NR networks is calculated to be 21%; this throughput loss level significantly exceeds the threshold level.  
In Figure 8, the SINR levels and throughput loss of the downlink channels in the FR2 band are illustrated.  
In scenarios where RedCap is deployed in the FR2 band, the average throughput loss of the downlink channel for public 5G NR networks is calculated to be 1.5%, which is under the acceptable levels.  
Figure 9 depicts the SINR levels and throughput loss for the uplink channels of the 5G NR victim network in the FR2 band.

In scenarios where RedCap is deployed in the FR2 band, the average throughput loss of the uplink channel for public 5G NR networks is calculated to be 0.7%, which is under the acceptable levels.  
Based on the studies conducted, it is evident that deploying RedCap in the FR1 band could result in a 4.5% reduction in throughput for both the downlink and uplink channels in public networks. While the downlink throughput reduction remains within acceptable threshold levels, the uplink channel experiences a more substantial decrease, surpassing the tolerable thresholds.  
In the case of FR2, RedCap deployment leads to minor throughput reductions of 1.5% and 0.7% for the downlink and uplink channels, respectively. This is attributed to the higher attenuation levels and more precise beamforming techniques inherent in the FR2 band, effectively mitigating interference. Table 5 outlines the specific throughput loss values for each channel in both the FR1 and FR2 bands of the 5G NR public networks.
