Can I download WiFi to my phone?

I'm curious, is it possible to actually download WiFi onto your phone? It seems like a common misconception among many people that they can simply 'download' WiFi like an app or a file. But from what I understand, WiFi is a wireless networking technology that allows devices to connect to the internet without the need for cables. So, is it really feasible to 'download' WiFi onto a phone, or is this just a misunderstanding of how WiFi works?
