The design and implementation of the active RFID location system

With the data services and multimedia services rapidly increasing,the demand for positioning and navigation are also increasing.But a perfect positioning technology is still not used,because of the positioning time,positioning accuracy and the complex environment conditions.To address these issues,the features and issues pertinent to several current typical positioning technology were analyzed.Finally,an active RFID location system was proposed,which is based on RFID technology.Analysis shows that this system has hige positioning accuracy,strong anti-jamming capability,wide positioning range and fits for the scenario when the tags number is large.
