Position triangulation using wifi

The fact that there are more Wi-Fi hotspots than trees in a city enables Google or Apple to identify your location by merely knowing the strength of Wi-Fi signals on your phone. This data is available for app developers through APIs which any developer can leverage to locate phones using Wi-Fi positioning.

The accuracy of Wi-Fi in the dense city can vary between 10 — 25m and in sub-urban areas with fewer access points 20 — m.

Start small, learn, and then grow. Yea that sounds like the best idea, in the words of steve baulldmer, experiment, experiment, experiment lol. You can post now and register later.

Example: So then i i read a little more and understood what would happen if i used two routers Example: So I understand things up to here, now when you bring a third router into the equation it looks like this. Example: I even understand that now I know where i am roughly but i could be at any point inside that triangle, how do i know where i am, or would the size of that triangle be dependant on how strong the routers broadcasting are?

Edited September 6, by Anton. Posted September 8, edited. Shortening the broadcast distance helps in that it shortens the radius around the AP. Meaning, if your device can see the AP, it's within just using an arbitrary number 25 ft instead of ft Which is fine I assume it also helps because being closer to the AP means a lesser chance of interference artificially weakening the signal and throwing your math off.

Your graphics are correct. Your understanding of the general concept is spot on. The actual process of finding that point within the three circles is called trilateration.

In order to overcome from all the disadvantages we are going to Wi-Fi triangulation method this will be continuously supplying of signals for transmitted the data through Wi-Fi and also all new developed technology having this facilities and also all upcoming technology and devices also having this Wi-Fi technology so its easy for navigating the places.

Our Proposed system which talks the about the technology of Wi-Fi and Wi-Fi triangulation method, the deals with forming up of Wi-Fi setup in the place where we need to access the navigation system through this a map is created and navigation is formed through the spotting up of place.

This is the technique will be very useful for finding up off the place inside any commercial buildings, colleges, school and house which will help the new people who are coming to the place can easily identify the places where they wants to go but one thing we need Wi-Fi point, in same way the people who are accessing the Wi-Fi some will use that Wi-Fi access for downloading or some illegal action will occur for that a secure system is arranged that we are presenting a firewall in the Wi-Fi accessing which helps to prevent from the illegal access of the Wi-Fi data transaction.

There wont be any damage, data loss and other technical issues that will not occur i. These are the extension and other facilities are providing for the navigation in indoor. Patwari, J. Ash, S.

Fig 2 Architecture Diagram of Navigation Setup The architecture diagram shows : a it consists of three Wi-Fi access point nmely Wi-Fi A, Wi-Fi B, Wi-Fi C; b These three are interconnected with Wi-Fi signal tracker and this Signal tracker is connected to Wi-Fi signal receiver; c This whole setup are connected to Wi-Fi signal analyzer; d This analyzer are connected to Location Position System the Location Positing System consists major sector they are distance predictor, local Mapping, navigation system which help to detect and navigate the places; e the local mapping is connected to indoor database from that we can access the map of the indoor places.

Location Positioning System Location Positioning System is term which for tracking or finding off place inside the navigation system. Distance Predictor The distance predictor is a method to find out the distance traveled knows distance predictor.

Local Mapping The local mapping is segment for creating Map for the local area which is help to find out the spot for the place in any local area.

Navigation System Navigation System main process of locating of place where the human are searching or for finding out the places in around the world by means of GPS, but in this project that are been used to find the spot of the Wi-Fi for navigation to locate places inside the college.
