DW3000 transmission distance

What is the maximum possible transmission distance of dw3000?

What channel? Do you need the answer in meters or feet…

Maximum possible distance is probably not a useful measure. If you are designing a system then you really want to know the maximum reliable distance.
Unfortunately it’s not so easy to say and will depend on the environment, your hardware and how you have the transmitter set up.
