Anchors distance setup

Hello,

I was looking for information on the best anchor positioning and found many useful tips. However, I am still not sure which point on the module to choose when measuring the distance between anchors when setting up the system.

The picture in the DWM3001C datasheet (p. 13: https://www.qorvo.com/products/d/da008289) shows the middle of the evaluation board. But what if the design gets slightly bigger, should I still use the middle as the reference point? Should I then use the DWM3001C module itself or the antenna?

I plan to position four anchors and measure the distances with a laser, but Iā€™m not sure where to point to minimise tolerance.

Thanks for any advice!

@TonyOlyr , the best way to take the measurement is from antenna to antenna as the antenna delay parameter is accounting from the chip to the antenna.
