Airport Card and Bluetooth Combined?

I recently bought a used and badly mistreated MacBook Pro 15" Unibody 2.4GHz Late 2008 at a very good price and have ordered several internal and external parts for it.

The bluetooth connection randomly fails between my Magic Mouse and Macbook Pro so I may have to replace another part because I'm 99% sure it's not a Magic Mouse problem ( battery strength is fine )

Am I correct in assuming that the Airport Card is combined with the Bluetooth on the same card ?
