Indoor Positioning System Using Wifi

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.

Indoor positioning system using wifi. With wi fi rtt devices will be able to use time of flight tof as opposed to measuring the. This information is then integrated into a code created in the android studio. For example existing customer hotspots cash register systems and routers from shops can be used. The following flowchart explains the working of an indoor positioning system.

Nonetheless despite wifi s shortcomings with fingerprinting sensor fusion and security hardening wifi becomes a good option for connecting indoor positioning systems. Wi fi access points or routers. 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 whitepaper proposes an efficient and reliable wi fi real time indoor positioning system using fingerprinting algorithm.

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. Wi fi round trip timing rtt part of the ieee 802 11 protocol is an example of where things are heading. Indoor positioning problem using wi fi signal fingerprints can be viewed as a machine learning task to be solved mathematically. The absolute position of a wifi tower is also calculated using the above information point 1 and 2.

The proposed positioning system. In most cases it is easy to install a wi fi positioning system since wi fi access points already exist in many buildings.
