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:
<channel>
to force a specific channel to be used when beaconing,
or, if <channel> is -1, to prohibit beaconing. If
<channel> 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/ASIE
Date: August 2014
KernelVersion: 3.18
Contact: linux-usb@vger.kernel.org
Description:
The application-specific information element (ASIE)
included in this device's beacon, in space separated
hex octets.
Reading returns the current ASIE. Writing replaces
the current ASIE with the one written.
What: /sys/class/uwb_rc/uwbN/scan
Date: July 2008
KernelVersion: 2.6.27
Contact: linux-usb@vger.kernel.org
Description:
Write:
<channel> <type> [<bpst offset>]
to start (or stop) scanning on a channel. <type> is one of:
== =======================================
0 scan
1 scan outside BP
2 scan while inactive
3 scanning disabled
4 scan (with start time of <bpst offset>)
== =======================================
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/<EUI-48>/
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/<EUI-48>/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/<EUI-48>/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>/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/<EUI-48>/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/<EUI-48>/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/<EUI-48>/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.
