You can have to Wireless adapters from inside a VMware Workstation guest OS if the adapter is a USB adapter and it's been connected to the guest (ie Wireless USB, 3G/UMTS USB Modem).
Workstation will not allow you to connect physical hardware in the PCMCIA/PCARD/ExpressCard slot to you're guest OS.
