We have observed on several occasiosions a noise issue it will manifest itself one of 2 ways with the evk1000 dev kits
- random noise with a standard deviation is much as 50cm
- the range measurement jumps from an correct range measurement to an incorrect range measurement
We have observed this several occasions when an anchor and node are line-of-site of another about 5m away. Anyone have an idea what could be causing this behavior? The technical support from Decawave we have got suggested that the problem could be a near-field related since we had metal within the anchor and tag’s 15cm metal-free zone
The following image illustrates our issue. Here we had 2 different configurations we wanted to compare (different channels and different mode) lets call them net1 and net2. Net1 and Net2 were mounted alongside one another on 2 different machines (one machine had net1 anchor 1 and net 2 anchor 1 and the other machine had net1 tag1 and net2 tag1). The figure illustrates this
We have the 2 networks mounted alongside one another so ideally they should be identical if you were to remove offsets. However, this noise issue is prevalent on the one network. Y axis is time and X axis is meters between each networks anchor 1 and tag 1
