Problems solved by technology

[0004] However, if the measuring node uses a fixed directional antenna, it cannot perform ranging for the moving target node; and, since the size of the collision domain of the wireless signal of the measuring node and the time occupied by each positioning determine the positioning capacity, therefore, If a fixed antenna is used to transmit wireless signals between the target node, it will occupy a large conflict domain, especially if the wireless signals sent by other wireless ranging nodes also reach this conflict domain at the same time, the difference between the two There will be signal collisions between them, resulting in inaccurate measurement results, or even failure to obtain measurement results
