[FIXED] Location tracking using triangulation

Issue

I have a double question regarding location tracking using triangulation (over wifi signal).

1. Does it also work outdoors?
2. Does it work on wifi networks that are protected? What I mean is that in Belgium, our different ISP's provide hotspot functionality which are only accessible when you are a customer. Is using the wifi signal always possible as soon as it is available? Or does it also require authentication before it can be made use of?

Edit: Do you know of some good and clear documentation/references on how to learn how to implement it for Android / iOS?

Solution

For iOS

Does it also work outdoors?

Yes, if there is WiFi signal

Does it work on wifi networks that are protected? What I mean is that in Belgium, our different ISP's provide hotspot functionality which are only accessible when you are a customer.

It does not require authentication. Not sure what networks it is using, but in cities it can be surprisingly accurate.

On iOS you just use the same API you use for GPS tracking - CLLocation. It uses appropriate technology based on capabilities of the device and required accuracy.
