UWB is a high-bandwidth, low-power, point-to-point radio
technology using a wide spectrum (3.1-10.6GHz). It is
optimized for in-room use (480Mbps at 2 meters, 110Mbps at
10m). It serves as the transport layer for other protocols,
such as Wireless USB (WUSB).

The topology is peer to peer; however, higher level
protocols (such as WUSB) might impose a master/slave
relationship.

Say Y here if your computer has UWB radio controllers (USB or PCI)
based. You will need to enable the radio controllers
below. It is ok to select all of them, no harm done.

For more help check the UWB and WUSB related files in
Documentation/usb/.

To compile the UWB stack as a module, choose M here.
