It’s also useful for position tracking systems, but most of the ones you’re. accuracy claims. This accuracy is further hindered by atmospheric conditions, obstacles etc. Such positioning systems also use the triangulation method to locate a target. In the recent years, many research showed that indoor positioning systems based on Wi-Fi fingerprints can achieve a high positioning accuracy. width by exploiting diversities on Wi-Fi devices to facilitate centimeter accuracy indoor localization. causes gross positioning errors, due to which systems with large bandwidth, and consequently fine multipath resolution capability, yield better performance [4, 5]. If SNR_in is 10 dB, the positioning accuracy is 0. The aim of this project is to create wireless positioning system for a school campus and track various costly assets.
