What: /sys/class/uwb_rc Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: Interfaces for WiMedia Ultra Wideband Common Radio Platform (UWB) radio controllers. Familiarity with the ECMA-368 'High Rate Ultra Wideband MAC and PHY Specification' is assumed. What: /sys/class/uwb_rc/beacon_timeout_ms Date: July 2008 KernelVersion: 2.6.27 Description: If no beacons are received from a device for at least this time, the device will be considered to have gone and it will be removed. The default is 3 superframes (~197 ms) as required by the specification. What: /sys/class/uwb_rc/uwbN/ Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: An individual UWB radio controller. What: /sys/class/uwb_rc/uwbN/beacon Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: Write: to force a specific channel to be used when beaconing, or, if is -1, to prohibit beaconing. If is 0, then the default channel selection algorithm will be used. Valid channels depends on the radio controller's supported band groups. Reading returns the currently active channel, or -1 if the radio controller is not beaconing. What: /sys/class/uwb_rc/uwbN/scan Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: Write: [] to start (or stop) scanning on a channel. is one of: 0 - scan 1 - scan outside BP 2 - scan while inactive 3 - scanning disabled 4 - scan (with start time of ) What: /sys/class/uwb_rc/uwbN/mac_address Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: The EUI-48, in colon-separated hex octets, for this radio controller. A write will change the radio controller's EUI-48 but only do so while the device is not beaconing or scanning. What: /sys/class/uwb_rc/uwbN/wusbhc Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: A symlink to the device (if any) of the WUSB Host Controller PAL using this radio controller. What: /sys/class/uwb_rc/uwbN// Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: A neighbour UWB device that has either been detected as part of a scan or is a member of the radio controllers beacon group. What: /sys/class/uwb_rc/uwbN//BPST Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: The time (using the radio controllers internal 1 ms interval superframe timer) of the last beacon from this device was received. What: /sys/class/uwb_rc/uwbN//DevAddr Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: The current DevAddr of this device in colon separated hex octets. What: /sys/class/uwb_rc/uwbN//EUI_48 Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: The EUI-48 of this device in colon separated hex octets. What: /sys/class/uwb_rc/uwbN//BPST Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: What: /sys/class/uwb_rc/uwbN//IEs Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: The latest IEs included in this device's beacon, in space separated hex octets with one IE per line. What: /sys/class/uwb_rc/uwbN//LQE Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: Link Quality Estimate - the Signal to Noise Ratio (SNR) of all packets received from this device in dB. This gives an estimate on a suitable PHY rate. Refer to [ECMA-368] section 13.3 for more details. What: /sys/class/uwb_rc/uwbN//RSSI Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: Received Signal Strength Indication - the strength of the received signal in dB. LQE is a more useful measure of the radio link quality.
