Does Quick Start require Wi-Fi connection?

Hi,

The article below says nothing about external Wi-Fi connection.

I don’t have two iPhones to test but the demo videos I watched on YouTube do not mention any external Wi-Fi connection.

I understand Wi-Fi is to be turned on but it’s for direct connection (side by side connection) like Bluetooth and Personal hotspot.  Why a connection to an external Wi-Fi would be required?

 Thanks  

This video answers my question, no external Wi-Fi is required as it works with a peer-to-peer connection (local Wi-Fi or Bluetooth). Internet is required to complete the applications download.
