6 Interfaces for WiMedia Ultra Wideband Common Radio
7 Platform (UWB) radio controllers.
9 Familiarity with the ECMA-368 'High Rate Ultra
10 Wideband MAC and PHY Specification' is assumed.
12 What: /sys/class/uwb_rc/beacon_timeout_ms
16 If no beacons are received from a device for at least
17 this time, the device will be considered to have gone
18 and it will be removed. The default is 3 superframes
19 (~197 ms) as required by the specification.
21 What: /sys/class/uwb_rc/uwbN/
24 Contact: linux-usb@vger.kernel.org
26 An individual UWB radio controller.
28 What: /sys/class/uwb_rc/uwbN/beacon
31 Contact: linux-usb@vger.kernel.org
37 to force a specific channel to be used when beaconing,
38 or, if <channel> is -1, to prohibit beaconing. If
39 <channel> is 0, then the default channel selection
40 algorithm will be used. Valid channels depends on the
41 radio controller's supported band groups.
43 Reading returns the currently active channel, or -1 if
44 the radio controller is not beaconing.
46 What: /sys/class/uwb_rc/uwbN/scan
49 Contact: linux-usb@vger.kernel.org
53 <channel> <type> [<bpst offset>]
55 to start (or stop) scanning on a channel. <type> is one of:
58 2 - scan while inactive
60 4 - scan (with start time of <bpst offset>)
62 What: /sys/class/uwb_rc/uwbN/mac_address
65 Contact: linux-usb@vger.kernel.org
67 The EUI-48, in colon-separated hex octets, for this
68 radio controller. A write will change the radio
69 controller's EUI-48 but only do so while the device is
70 not beaconing or scanning.

77 A symlink to the device (if any) of the WUSB Host
78 Controller PAL using this radio controller.

83 Contact: linux-usb@vger.kernel.org
85 A neighbour UWB device that has either been detected
86 as part of a scan or is a member of the radio
87 controllers beacon group.
89 What: /sys/class/uwb_rc/uwbN/<EUI-48>/BPST
92 Contact: linux-usb@vger.kernel.org
94 The time (using the radio controllers internal 1 ms

131 KernelVersion: 2.6.27
132 Contact: linux-usb@vger.kernel.org
134 Link Quality Estimate - the Signal to Noise Ratio
135 (SNR) of all packets received from this device in dB.
136 This gives an estimate on a suitable PHY rate. Refer
137 to [ECMA-368] section 13.3 for more details.

144 Received Signal Strength Indication - the strength of
145 the received signal in dB. LQE is a more useful
146 measure of the radio link quality.
