Transitioning from DWM1001 to DWM3001 tips and insight

I’m not sure what you are expecting in terms of better range, performance and overall capabilities.
If anything the range is slightly lower in the DWM3001. Performance is basically the same.

The DW3000 adds three new features - support for channel 9, built in security/encryption and angle of arrival (with the appropriate parts and antennas). Unless you need one of those features there is no reason to switch.

Channel 9 is the big one, channels 1-4 can clash with some of the 5G phone networks. Channels 5&7 can clash with some of the newer WiFi bands (from memory WiFi 6e).
