DWM1001-Dev very short range coverage

Wireless Connectivity Ultra-Wideband

Hello,

I just installed 4 anchors if DWM1001-Dev and configured another unit to be a Tag, the room is 7m X 10m - 3m height open space, all concrete without any metal material around. all anchors are in line of sight. however I get a very poor performance and short coverage. the best stable position reading I got from the tag is when all the anchors are installed 4 meter far from each other and the coverage is only half of the room.

summery: the tag can only read the Anchors when it is less than 5 meters !! shouldn’t it be 290m as specifics says?

ironically, the BLE of the modules has more range than the UWB communication!

I have configured all the DWM1001 by android tablet. and all are power by 2A USB even the tag.

I have read on this forum about disappointments of the DWM1001 but I think my experience is the worst. am I missing something here? do I need to increase the out-of-box transmission power?

I appreciate any help. thank you

Hi!
Just to indicate that I have similar problems.
I also measured the same. Unfortunately, I did not find anything in the documentation that would suggest an increase in range.
Although I can read the txpower property with the utpg function in the application description, I cannot interpret the resulting number in dBmV. My instrument is not in this frequency range. I think the antenna is inappropriate or is not properly tuned. I got stuck in my project.
