Your system is limited to what Apple offered for Bluetooth and WiFi services as only theirs have the needed OS drivers. If you are running Windows or Linux you might be able to install a PCI board which can support newer options.
The first Mac Pro Mid 2016 offered them as an add-on option, Early 2008 and newer models had them as standard.
Apple offered a Bluetooth 2.0 + EDR plug-in board and AirPort Extreme card (802.11a/b/g/n) both fitted into the main planar logic board.
