your question lead to a more complex answer than you might think. Getting best performance from the DW1000 while complying with the regulation is a bit like adjusting the engine. There are many parameters and details and you need to select what would best fit your application.
The performance depends on the parameters
- Data rate, preamble length
a) affects total number of data/measurements, power consumption, receiver sensitivity
b) allowed transmit power - this is related only with frame length. You need to ensure not to transmit more than once from the same node if Smart Power is used.
- Channel - CH2 will give you better range, but it cannot be used on DWM1001 since the antenna is tuned for CH5.
- Other parameters like XTAL trim will also affect the sensitivity.
Configuring the chip is simple as Andy has mentioned. But you need to play a bit with those parameters to find what works best for you. I would suggest to start with this frame length calculator:
which would help you to see the relation between the parameters and occupied air-time.
So for PANS you cannot change the data rate or preamble length because the frames will take longer to transmit and it will not fit in the slot timing scheme used in PANS.
