Zusammenfassung:	The invention discloses a label wireless positioning method and system. The method comprises the steps that a main base station sends a main positioning signal and a main sending timestamp to at least three auxiliary base stations communicating with the main base station and a label; each auxiliary base station generates respective auxiliary receiving timestamp according to the main positioning signal; each auxiliary base station sends respective auxiliary positioning signal and auxiliary receiving timestamp to the main base station and the label; the main base station generates respective main receiving timestamps according to the auxiliary positioning signals and the auxiliary receiving timestamps sent by the auxiliary base stations; the label generates a label main receiving timestamp according to the main positioning signal, and the label auxiliary receiving timestamps are generated respectively according to the auxiliary positioning signals returned by the auxiliary base stations; then coordinate positio
