And how does all this relate to WiFi remote??
I will be buying a decent laptop for this activity.

Can't say about Wi-Fi on the 70D, I can say about direct connecting Wi-Fi on the 6D and I say, don't count on it.
It's awkward at best to set up, both on the camera and on the other device.
Once, or more like IF you get both devices connected they'll lose connection easily, while connected there is unacceptable lag, NO video over Wi-Fi.
I think I did try the infrastructure mode which requires a router or other access point type device, that connection was solid, lag and delay was still there, still no video possible.
If you have a smartphone, Apple or Android, download the free EOS Remote app by Canon from iTunes or Google Play, see for yourself if what I've posted is true.
I'm pretty sure (that means I haven't tried) the EOS Utility can connect your PC to your camera over Wi-Fi, try setting that up at least to test Wi-Fi connectivity.

If you need the range of wireless, go with CamRanger or similar. CamRanger handles video if you need that.
CamRanger can connect to a wide variety of Canons and Nikons, any Wi-Fi equipped phone, tablet or PC can be used for camera control.
CamRanger uses a wired USB connection to the camera, CamRanger is now the camera's Wi-Fi transceiver.

If you can stay within the USB cabled length restriction of 16 feet/3 meters (can double that with fancy repeater cables), tethered cabled rocks.
For about the same or less than a CamRanger device, you can get an Android tablet, way way less than CamRanger PLUS a laptop.
The only hardware requirement to tether android over USB is that the device must support the USB Host protocol, which is most all currently available models.
Then choose by screen and budget.
For short runs, you've already got one needed cable, it'll plug into a USB Host/OTG adapter dongle/cable. (OTG = On The Go, Host and OTG are the same thing)
OTG cables go for as little as a dollar on Amazon.
Download a ~$10 app like DSLRcontroller or Helicon Remote and go.

If you want full editing capabilities in the field same like your desktop, you need a laptop, likely an Expen$ive one.
If you want full upload capabilities in the field, be prepared to pay for lots of wireless (cellular) bandwidth.
