Indoor Positioning System Using Wifi Project

Indoor localization system using wi fi technology.

Indoor positioning system using wifi project.

Indoor positioning system ips aims at wirelessly locating objects or people inside buildings based on magnetic sensor network or other source of data. 4th year project indoor positioning system 1. The absolute position of a wifi tower is also calculated using the above information point 1 and 2. Suitable sdks with their features for indoor navigation are listed below.

This project contains two files. Nonetheless despite wifi s shortcomings with fingerprinting sensor fusion and security hardening wifi becomes a good option for connecting indoor positioning systems. The system is built to use wifi signals and map the signal strength locations so as to guide user about his exact location in the indoor environment. Active research has shown that indoor positioning.

This information is then integrated into a code created in the android studio. Wi fi round trip timing rtt part of the ieee 802 11 protocol is an example of where things are heading. 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. This was a course project under digital communications course.

With wi fi rtt devices will be able to use time of flight tof as opposed to measuring the. Wifi is widely available in indoor spaces so it may seem like a logical default choice for indoor positioning systems but it has security and accuracy drawbacks. When looking for a sophisticated indoor mobile wayfinding system it s important to measure costs against other criteria. 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.

So if you re thinking about using your existing wifi infrastructure to enable indoor positioning use cases and want to avoid any unpleasant surprises here are some reasons why you might want to reconsider. In this project the test environment is selected to be the building of the computer. The following flowchart explains the working of an indoor positioning system. The major consumer benefit of indoor positioning is the expansion of location aware mobile computing indoors such as augmented reality store navigation etc.
