I’m a developer working on wearable devices to improve worker safety using Bluetooth and UWB technologies. Up to now, I’ve been using the DWM1001 module, but my company is looking into switching to the DWM3001 for better performance, range, and overall UWB capabilities.
We’ve just started exploring the transition. We got our hands on the DWM3001 and the QM33120WDK1 dev kit. I’m reaching out to see if anyone here has experience working with the DWM3001. Any tips, example projects, libraries, or “gotchas” to look out for would be super helpful.
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).
Hi AndyA, thanks for your reply. When i talk about increasing dwm performace , i am talking about in an increase of the communication range between tag and anchors both in LOS and non LOS condition. Datasheet talks about 500 meters of possibile communication range but maybe it cannot be reach with these antennas.
If you look in the forums there are people reporting shorter maximum ranges with the DW3000, I’ve not noticed anyone reporting a longer range.
All things being equal the DW1000 has two things going for it in terms of range - it supports a lower data rate mode which in theory gives more receive sensitivity and it supports lower frequencies. Free space path losses increases with frequency so for the same power and sensitivity you’ll get more range at a lower frequency.
The DW3000 maximum power is also lower than the DW1000, it’s still over the regulatory limits so if you have to stay within the limit then this doesn’t matter. But if you ignore the limits you’ll get a lower maximum output.
Hi Alessandro, we just completed a year-long project in collaboration with the Colorado School of Mines doing just the same thing. We would be interested in discussing a further collaboration with your organization to bring this to market. If this sounds interesting, please reach out to me directly at apdobaj@augsensetech.com and we can discuss in more detail. Looking forward to hearing from you. Regards,
Tony Dobaj, CTO Augmented Sense Technologies.
