I know where it came from but I want to know the exact model of the device and what it can use to? I have found it isn't WiFi shield!

What’s the name of the module!

It looks like the official Arduino enclosure box, except it is purple in color, and presumably somebody drilled a hole for the antenna: http://store.arduino.cc/ww/index.php?main_page=product_info&cPath=11&products_id=79
