DJI RC vs RCN1 Transmission Comparison

When I purchased my DJI Mini 3, I read that the transmission technology the controller used was called Occusync 2. Upon further investigation, I realized that the Mini 3 was built for O2 transmission; however, O3 transmission is about power AND interference modulation. Theoretically, the DJI RC controller should outperform the RCN1 by allowing the drone to fly further.
Ultimately, my guess is correct. the RC allows the drone to fly about 2000 ft further than the RCN1.
