This was a course project under digital communications course.

Indoor positioning system using wifi project.

When looking for a sophisticated indoor mobile wayfinding system it s important to measure costs against other criteria. 4th year project indoor positioning system 1. With wi fi rtt devices will be able to use time of flight tof as opposed to measuring the. Indoor localization system using wi fi technology.

Active research has shown that indoor positioning. Another benefit to implementing wi fi as an indoor positioning technology is that the accuracy will only improve as more infrastructure is built and newer technologies are developed and deployed. The major consumer benefit of indoor positioning is the expansion of location aware mobile computing indoors such as augmented reality store navigation etc. Indoor positioning system ips aims at wirelessly locating objects or people inside buildings based on magnetic sensor network or other source of data.

2015 3 developed a system using three wi fi emitters and a single receiver vasisht kumar and katabi 2015 exploited the relationship between the time of flight of electromagnetic signals and their spectral phase. Our system is aimed to help the blind as well as knowing indoor user location in case of smoke or dark environment rooms. The absolute position of a wifi tower is also calculated using the above information point 1 and 2. Apinfo py this python script will gather the details of all the available access points within the range of the laptop.
