Garmin Drivesmart 76

This is probably a silly question for the more tech savvy than me. I have activated the Traffic App for my Garmin using my I Pad. I don’t have an I Phone.
Do I need to be connected to my WiFi and have the I Pad switched on whist I am using the Garmin. 

I thought an update regarding the Traffic App for my Garmin would be worth noting. 
We traveled as far as Edinburgh with it activated. WiFi enabled and I pad powered up but nothing showed up as expected as there were no delays.
On the outskirts of Edinburgh the Traffic stopped due to an accident. We were stationary for nearly an hour and nothing showed up on the Garmin suggesting a hold up or an alternative route. Maybe theres something I havnt set up right or the system didn’t know about the hold up but for now I have disabled the Traffic setting on the Garmin. 
With me only using the Garmin for trips away that are not critical to timings I havnt been too bothered about hold ups so it’s just an option that the Garmin came with so I wont bother for now.

Thanks for all suggestions folks. The biggest problem I have with this tech stuff is that I am too much of a Luddite to bother with a smart phone. 
My I pad will do if I need WIFI . To be honest I find the I phones too small and complicated. People wandering about with their nose in a phone or playing with their smart watch things I don’t get.
Whilst filling up with diesel on the Isle of Skye a guy was trying to pay for fuel with his smart watch and having trouble. I just waved my card at the machine done and out without upsetting the rest of the customers. 
As long as the sat nav tells me we’re to go and warns me of speed limits that’s fine. The bigger screen and updated maps are a vast improvement to the old one so it’s not a total waste of money.
