ad-hoc wireless UWB network

Several Dell notebooks comprise a built-in WPAN/UWB adapter (Precision M4400, Latitude E6400 or E6500).

This adapter is used to provide a wireless connection to several USB devices throught a Wireless USB hub or to docking station.

Is it possible to set up an ad-hoc network in using this adapter?

I mean, is this WPAN/ UWB adapter compliant with the WiNet standard, ie compatible with "IP over UWB"?

For example, is it possible to set up a notebook provided with this WPAN/ UWB adapter as a host to share an internet connection with several other notebooks provided also with this WPAN/ UWB adapter?
