Ultra-WideBand (UWB) radio technology supports high bandwidth for wireless devices. UWBA is a miscellaneous module and it supports radio controller drivers for UWB based devices like HWA (Host Wire Adapter), WHCI (Wireless Host Controller Interface) and so forth. For example, both HWA radio controller driver (hwarc) and whci driver register to uwba during attach.
UWBA provides a series of common interfaces for drivers that support UWB radio technology. Each radio controller driver register itself as a UWB dev to the uwba model in the attach entry, then other driver or module can control this device to perform the UWB functions through a list of common interface. For example, a hwahc driver can control the hwarc driver to scan in a specific channel, start/stop beacon, manage device/MAC address, and so forth.
