Network scalability with weight analysis based on UWB indoor positioning system

Compared with other positioning technologies, UWB positioning technology has the absolute advantages in the accuracy, the real-time performance and the wide-band. It can achieve the positioning accuracy of centimeter level. The maturity of wireless clock synchronization algorithm, TDOA (Time Difference of Arrival) positioning algorithm and the multi tags access provides a good foundation for UWB positioning system. This paper applied weight analysis in network scalability to achieve the efficient network scalability with better accuracy of multi tag access.
