Abstract
With the development of social services, people’s living standards improve further requirements, there is an urgent need for a way to adapt to the complex situation of the new positioning technology. In recent years, RFID technology have a wide range of applications in all aspects of life and production, such as logistics tracking, car alarm, security and other items. The use of RFID technology to locate, it is a new direction in the eyes of the various research institutions and scholars. RFID positioning technology system stability, the error is small and low-cost advantages of its location algorithm is the focus of this study.This article analyzes the layers of RFID technology targeting methods and algorithms. First, RFID common several basic methods are introduced; Secondly, higher accuracy to political network location method; Finally, LANDMARC algorithm will be described. Through this it can be seen that advanced and efficient algorithms play an important role in increasing RFID positioning accuracy aspects.Finally, the algorithm of RFID location technology are summarized, pointing out the deficiencies in the algorithm, and put forward a follow-up study of the requirements, the vision of a better future RFID positioning technology.

1 Introduction ways to quickly prepare targeted indoor new technology, so the radio frequency technology run into people's vision
With the rapid development of radio frequency to become a scientific research institutions and scholars identification (RFID) technology, RFID technology sought after star
Radio frequency identification technology is a nontechnology originated during the beginning of World War II, the Allies to analyze and judge the enemy and friendly contact technology, the main principle is through electromagnetic coupling or electromagnetic coupling to ships or aircraft using wireless technology
Summary
1 Introduction ways to quickly prepare targeted indoor new technology, so the radio frequency technology run into people's vision. The target tag to the reader the propagation time t1, t2, t3, this way, they will know the distance of the target tag to the reader is Ri = C * ti, according to the mathematical method, can be assumed that the position coordinates of the target tag (X0, Y0), the following relation formula is as follows:
