Wi-Fi routers operating on the 2.4GHz frequency can reach up to 45 metres (150 feet) indoors and 90 metres (300 feet) outdoors,
Wi-Fi routers operating on the 5.0GHz frequency can reach up to 15 metres (50 feet) indoors and 30 metres (100 feet) outdoors.
This is dependent on any obstructions between the two devices that want to connect with each other of course e.g internal walls, electrical interference, buildings, etc .
The WiFi transmission distance for mobile phones will be less than this as they aren't as powerful as routers. So whilst they may be able to detect WiFi networks at the above distances they cannot connect to them, due to no communication setup between the two devices e.g. phone and router, as the receive signal level at the router end, may be too low for a stable connection.
Bluetooth has an effective operating distance of 10 metres (33 feet) but I'm not sure if this is also applicable to mobile phones.
