This is a wireless module for some Samsung products.

 * BD-D8500A/XY (Blu-ray player), shell-less module

"48DNUB06.SGD", "WiDT Ver. 0.3", "34x36mm, 1.0T", and "2010.09.07" is silkscreened on the board in the FCC photos (very likely indicating Wistron NeWeb manufacture for this particular unit). A label with a MAC (OUI E4:7C:F9, Samsung) is also affixed to the device in the FCC photos.

Some models in the wild is labeled with "BN59-01130A", "WiFi Module", and "T77H249.01".. which would seem to indicate that Foxconn is manufacturing at least some units.
 * Others are labeled somewhat differently.
