What was the UWB measurement setup?
One of the two radios was put on the stool 1m high to avoid multipath from the floor. And the other was enclosed within an insulated wooden box. This box helps prevent multipath signals from arriving at a receiver. Between the radios were placed materials such as a concrete wall and plywood, which were put closer to the insulated wooden box. To get measurement at different distances, we fixed the concrete wall and insulated box and moved the radio on the stool.
