MDEK1000 range and accuracy

[chrisfsampaio]

Hello,

I’m starting a POC project and would like ask some questions regarding the MDEK1001 kit:

1. What would be the estimated range of the system on a closed environment given that at least 3 anchors are in line of sight at all times?
2. I read the accuracy is typically under 10 cm, I’m assuming that the factors driving this are obstacles and maybe distance to anchors. Is that correct? Any recommended setup to increase accuracy?
3. I also read that the maximum update rate is 10hz, is that a hardware or software limitation?
4. What are the key differences between the MDEK1001 and TREK1000 kits? Does one have more accurate chips than the other?

Thanks! And sorry if the questions are too dumb, I’ve just found out about UWB.

1. What would be the estimated range of the system on a closed environment given that at least 3 anchors are in line of sight at all times?

module - module range (in the azimuth plane) is about 50m, this range will vary if the modules are not on the same plane/orientation, so generally the range is about 30-50 m

2. I read the accuracy is typically under 10 cm, I’m assuming that the factors driving this are obstacles and maybe distance to anchors. Is that correct? Any recommended setup to increase accuracy?

yes, the modules have been calibrated, and again this is in the azimuth plane, the actual accuracy will depend on the module orientation and environment

3. I also read that the maximum update rate is 10hz, is that a hardware or software limitation?

this is the limitation of on-board SW (PANS). the max tag location update rate is 10 Hz

4. What are the key differences between the MDEK1001 and TREK1000 kits? Does one have more accurate chips than the other?

Same DW1000 IC in both. The PANS SW that comes with MDEK/DWM1001 is closed system with a couple of APIs. It is a scalable system, much closer to final product than TREK1000. TREK is a demo system, not scalable, but the code is open/free and all of the DW1000 radio parameters can be modified.

Thanks! And sorry if the questions are too dumb, I’ve just found out about UWB.

enjoy playing with the kits!
