原标题:Is it possible to use 1 wifi access point to locate android mobile or would i need 3 to triangulate?

I m working on a project but i want to try if i can locate my position using 1 wifi access point because i only have 1 at home, or would i need to go somewhere where there are atleast 3?

这取决于你们是否需要阅读。 典型的wi-fi点将具有30米室内或90米室外面。

So, if you can actually locate the wi-fi point perfectly and you don t need better than 90m resolution (although, technically, that s probably an up-to-180m error), one should be fine.

If you need more resolution, the more points you can get (assuming of course the points aren t sitting on top of one another in a rack or something) should allow you to refine your position.

It is like xyz coordinate system. With one Wifi AP you will know the distance from the AP but not the direction. With two wifi APs you will know the location within a 2d plane (only the positive plane). You will need a third wifi AP for the 3rd dimension.
