Can someone explain the Wifi feature please ?

[Externet]

Hi all. I would take an idiotproof explanation...

The X2 Premium mini has the Wifi feature, and comes with the wireless 802.11 b/g/n 2.4GHz USB adapter antenna.

Is it to transmit TV from the X2 receiver to a TV with USB input jack and another of those antennas in the TV ?
Is it to transmit TV from the X2 receiver to a laptop with built-in Wifi and see the programming on the laptop screen ?
Is it for the X2 receiver to receive TV from a laptop with built-in Wifi playing internet video as Youtube and convey to the TV on HDMI ?
Is it for the X2 receiver to receive internet TV from a wireless router and convey it to a a TV on HDMI ?
Is it for the X2 receiver to receive internet video as Youtube playing from a laptop with built-in Wifi ?
Other, none or which of the above ?

That USB Wifi antenna included with the X2 Premium mini; is it the same type or useable if I connect it to a printer USB port to obey a laptop with built-in Wifi to print wirelessly ?
Thank you.
