I don't think you understand a wedge adapter; unless you purchase one with a fairly expensive RF link, it's attached to the same keyboard cable as the keyboard itself - it'll be within a few feet of the PC. RF devices add a considerable cost - on the order of an additional $1500-2000 for a short range RF link that attaches via wedge. It's not a device that attaches to the PC and you go running around a warehouse with to duplicate the functionality of a keyboard remotely - even the relatively expensive short range RF wedges only work to about the same distances as wireless keyboards and mice. The wedge interface is physically attached to the PC, and operates in parallel with the keyboard, so that you can scan a barcode rather than type a value in a field.

To do remote scanning applications, I'd recommend implementing a wireless LAN with a CE-box containing a scanner for the remote operation. The CE box will not be able to run a VFP app directly - it could connect via a product like Citrix, or could run a VFP COM server remotely via DCOM, but VFP does not run directly on CE. Self-contained CE-based scanners with RF LAN interfaces commonly run in the $5,000 range.
