Ive come across 2 types of routers, first one receives the internet signal wirelessly through radio waves and transmits it to the computer next to it.

The other receives the signal from normal ADSL from a plug in the wall and then transmits to the computer close to it via a wireless antenna. Which one is called WiFi and what is the difference between them exactly?

Also if I wanted to access the internet from a smart phone would it work on both types?

The first kind you mention is probably a wireless repeater. (Unless when you say it transmits to the computer next to it you mean it is by ethernet. In that case it would be a wireless bridge)

The other is a wireless router which takes a hard wired connection and broadcasts a wireless network that wifi enabled devices can join.

You should get the wireless router first.
Then if you need extra range, you could add a wireless repeater to your setup.
