How many anchors and tags does the positioning system require?
TWR mode theoretically requires at least 3 anchors. TDOA mode requires at least 4 anchors. Each set of anchors can support up to 1,000 tags, and the coverage should be determined according to the field environment. Generally, a set of anchors can cover an area of about 800 square meters. The more anchors, the higher the positioning accuracy and the larger the coverage area.
