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 start beaconing on a specific channel, or stop beaconing if is -1. Valid channels depends on the radio controller's supported band groups. may be used to try and join a specific beacon group if more than one was found during a scan. 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.
