How will you make sure of that, though? Only a tiny fraction of smartphone users will bother to connect to your wifi, and it'll be a skewed sample.

By making sure your steel-reinforced concrete mall walls are thick enough to block proper 3G/4G reception (no, really, reception is pretty bad in a lot of indoor places).

But still, I agree, it would be very hard to have everyone connect to your wifi.

it's hard to get everybody, but it's easy to get a significant sample. just set up an open network called Starbucks WiFi and watch all the iPhones connect to it

But the device is still visible on wifi even if it does not connect. Some phones tend will try to connect to known networks pro-actively and will leak the SSID of those networks.
