Dell H5WD3 WLAN antenna assembly cover is a replacement notebook part identified by its exact MPN. It is a cover for the WLAN antenna assembly, providing a cover component for the laptop’s wireless antenna setup.
The distributor lists the Dell Latitude 3540 as the compatible model. The item type is specified as a cover, so its documented role is to form part of the WLAN antenna assembly rather than serve as a standalone wireless adapter.
