Throughput lower than TCP at MANET(mobile Ad-hoc NETwork)

Nobody has claimed this yet.

Hello, I've been doing some throughput performance tests comparing lsquic with the TCP.
In the ethernet, lsquic can get higher throughput than TCP in almost every Packct Loss Ratio case.
However, when I test it in wireless environment, it seems lsquic has no performance advantage adding RFI(radio frequency interference).

Here is my network topology
1. pc1(Personal Computer) and pc2 connect to AP1(access point / WiFi router) by wireless, and use them to do throughput test comparing lsquic with the TCP.
2. pc3 and pc4 connect to AP2(the wifi channel is the same as AP1),use iperf to do tcp/udp throughput test for adding RFI.

In the experiment above, pc1 use lsquic/tcp for requesting a file of 60 MB from pc2, and calculate the throughput by time it takes.
In this case, it shows that the throughput of lsquic(Cubic/BBR) is lower than TCP most of the time.

Have you encountered similar phenomena in wireless weak environment?
Could you give me some advice, because I cann't find any effective ways to improve lsquic throughput in this case now.

No source files or tests are named. Start by reproducing the reported 60 MB lsquic-versus-TCP throughput test in the described two-AP wireless topology with interference, comparing Cubic and BBR, then inspect the relevant transport and congestion-control paths; done requires identifying a reproducible cause or measurable improvement.
