Throughput limitations when using Simu5G for real-time simulation

[zy-jack]

Hello,

I'm using the extclientserver example code in the emulation provided by Simu5G for simulation. No matter how I adjust the carrierFrequency and numBands parameters, the simulated throughput doesn't improve. Specifically:

When the carrierFrequency is set to 3.5GHz and numBands is set to {30, 40, 50, 60}, the throughput for both the receiver and transmitter is only 20Mbps when using iperf3 in TCP mode; when using iperf3 in UCP mode, the throughput is only 35Mbps; and when the carrierFrequency is set to 4.9GHz, the throughput remains essentially unchanged.

When the carrierFrequency is set to 3.5GHz and numBands is set to {80, 90, 100}, the throughput for both the receiver and transmitter is only 17Mbps when using iperf3 in TCP mode; when using iperf3 in UCP mode, the throughput is only 30Mbps; and when the carrierFrequency is set to 4.9GHz, the throughput remains essentially unchanged.

Is the throughput of Simu5G limited when performing real-time simulation?
