36 .Nd list channels and transmit power for a country/regulatory domain
46 displays the list of frequencies and the associated maximum transmit
47 power permitted within a regulatory domain and/or country.
49 If no command line options are given, a default country (\c
52 Country and regulatory names are case insensitive.
54 The following options are available:
55 .Bl -tag -width indent
59 will display B channels only if they are not also marked as available for
60 use as G channels and similary for A and T channels.
63 will list all channels.
65 Calculate channels not assuming extended channel mode.
67 Enabling debugging in the HAL code that calculates the available channels
68 and transmit power values.
70 Provide a list of all known country and regulatory domain names.
72 Calculate channels and transmit power for operation in
80 (or the first two letters).
82 Mark passive scan channels with lower case letters and active
83 scan channels with upper case letters.
85 Mark channels that require DFS with a
88 Mark channels that have a 4ms packet limit with a
91 Display IEEE channel numbers instead of frequencies.
93 Display frequencies (default).
95 Display only 11A channels.
97 Display only 11B channels.
99 Display only 11G channels.
101 Display only Turbo channels.
104 The following demonstrates how to list the permissible frequencies
105 and maximum transport power per channel for use in Spain:
110 SPAIN (ES, 0x2d4, 724) NULL1_WORLD (0x3, 3)
111 2412G 14.0 2417G 14.0 2422G 14.0 2427G 17.0 2432G 14.0 2437G 17.0
112 2442G 14.0 2447G 17.0 2452G 17.0 2457G 14.0 2462G 17.0
115 Each frequency has a suffix that is one of:
121 according to whether the channel is usable with 802.11g, 802.11b,
122 802.11a, or Atheros Turbo mode.
123 All channels listed as
127 Likewise, all channels listed as
135 are only usable in those modes.
138 option is specified passive scan channels are marked with a lower case
144 The transmit power is given in units of dbM.
146 Various diagnostics about unknown regulatory domains and/or country
147 codes may be encountered.
150 option for a list of valid names.
158 use the HAL to calculate the set of channels.
159 The transmit power calculations are done by emulating
164 read the actual EEPROM contents from a device this emulation may lag
165 behind current practice.
167 The HAL reset logic should be used to calculate the transmit power
168 for each channel instead of using a separate copy of the code.
169 The data presented by
171 are the expected values; for compliance testing one must measure the actual
172 operation of the driver and the HAL.
