5Description:
6 Interfaces for WiMedia Ultra Wideband Common Radio
7 Platform (UWB) radio controllers.
8
9 Familiarity with the ECMA-368 'High Rate Ultra
10 Wideband MAC and PHY Specification' is assumed.

14KernelVersion: 2.6.27
15Description:
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.

32Description:
33 Write:
34
35 <channel>
36
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.
42
43 Reading returns the currently active channel, or -1 if
44 the radio controller is not beaconing.

50Description:
51 Write:
52
53 <channel> <type> [<bpst offset>]
54
55 to start (or stop) scanning on a channel. <type> is one of:
56 0 - scan
57 1 - scan outside BP
58 2 - scan while inactive
59 3 - scanning disabled
60 4 - scan (with start time of <bpst offset>)

66Description:
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.

133Description:
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.
