This prototype can use an wi fi network with at least two access points to create an indoor positioning system based in wifi triangulation.
Wifi indoor positioning system.
While wifi based indoor positioning may score when it comes to cost efficiency ble based systems ensure a more accurate and reliable solution.
Indoor positioning systems ips can most easily be explained as gps for indoor locations.
Setting up an indoor positioning system using wi fi.
Wi fi based indoor positioning system.
Ips is like a network of devices which helps us to wirelessly find out the location of various objects or people inside the buildings it completely relies on the nearby anchors or local tags which help us to provide the information regarding the environmental aspects that help us to.
We travel indoors by using indoor positioning systems ips.
It is used where satellite navigation such as gps is inadequate due to various causes including multipath and signal blockage indoors or where acquiring a satellite fix would take.
This project contains two files.
The wifi based indoor positioning system consist of two parts the positioning server and the positioning client 3.
Wi fi positioning system wps also abbreviated as wips or wfps is a geolocation system that uses the characteristics of nearby wi fi hotspots and other wireless access points to discover where a device is located.
In most cases it is easy to install a wi fi positioning system since wi fi access points already exist in many buildings.
It s an android prototype app written in java.
The whole system consists of three modules namely mobile phone.
Apple restrictions are making wifi based wayfinding impossible and recent android software updates are introducing new obstacles as well.
The app receives the signal 3 or more wi fi access points and.
Software part mainly consist includes three aspects web server location.
It is a technology that allows users to accurately pinpoint the location of people or assets inside a building using smartphones mobile devices tracking tags or other devices.
The ideia is quite similar to gps positioning system.
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.
Nonetheless despite wifi s shortcomings with fingerprinting sensor fusion and security hardening wifi becomes a good option for connecting indoor positioning systems.
For example existing customer hotspots cash register systems and routers from shops can be used.
