42 Here are all 11b/11g/11a rates and modulations:
43
44 11b 11g 11a
45 --- --- ---
46 1 |B |B |
47 2 |Q |Q |
48 5.5|Cp |C p|
49 6 | |Od |O
50 9 | |od |o
51 11 |Cp |C p|
52 12 | |Od |O
53 18 | |od |o
54 22 | | p|
55 24 | |Od |O
56 33 | | p|
57 36 | |od |o
58 48 | |od |o
59 54 | |od |o
60
61 Mandatory:
62 B - DBPSK (Differential Binary Phase Shift Keying)
63 Q - DQPSK (Differential Quaternary Phase Shift Keying)
64 C - CCK (Complementary Code Keying, a form of DSSS
65 (Direct Sequence Spread Spectrum) modulation)
66 O - OFDM (Orthogonal Frequency Division Multiplexing)
67 Optional:
68 o - OFDM
69 d - CCK-OFDM (also known as DSSS-OFDM)
70 p - PBCC (Packet Binary Convolutional Coding)
71
72 The term CCK-OFDM may be used interchangeably with DSSS-OFDM
73 (the IEEE 802.11g-2003 standard uses the latter terminology).
74 In the CCK-OFDM, the PLCP header of the frame uses the CCK form of DSSS,
75 while the PLCP payload (the MAC frame) is modulated using OFDM.
76
77 Basically, you must use CCK-OFDM if you have mixed 11b/11g environment,
78 or else (pure OFDM) 11b equipment may not realize that AP
79 is sending a packet and start sending its own one.
80 Sadly, looks like acx111 does not support CCK-OFDM, only pure OFDM.
81
82 Re PBCC: avoid using it. It makes sense only if you have
83 TI "11b+" hardware. You _must_ use PBCC in order to reach 22Mbps on it.
84
85 Preambles:
86
87 Long preamble (at 1Mbit rate, takes 144 us):
88 16 bytes ones
89 2 bytes 0xF3A0 (lsb sent first)
90 PLCP header follows (at 1Mbit also):
91 1 byte Signal: speed, in 0.1Mbit units, except for:
92 33Mbit: 33 (instead of 330 - doesn't fit in octet)
93 all CCK-OFDM rates: 30
94 1 byte Service
95 0,1,4: reserved
96 2: 1=locked clock
97 3: 1=PBCC
98 5: Length Extension (PBCC 22,33Mbit (11g only)) <-
99 6: Length Extension (PBCC 22,33Mbit (11g only)) <- BLACK MAGIC HERE
100 7: Length Extension <-
101 2 bytes Length (time needed to tx this frame)
102 a) 5.5 Mbit/s CCK
103 Length = octets*8/5.5, rounded up to integer
104 b) 11 Mbit/s CCK
105 Length = octets*8/11, rounded up to integer
106 Service bit 7:
107 0 = rounding took less than 8/11
108 1 = rounding took more than or equal to 8/11
109 c) 5.5 Mbit/s PBCC
110 Length = (octets+1)*8/5.5, rounded up to integer
111 d) 11 Mbit/s PBCC
112 Length = (octets+1)*8/11, rounded up to integer
113 Service bit 7:
114 0 = rounding took less than 8/11
115 1 = rounding took more than or equal to 8/11
116 e) 22 Mbit/s PBCC
117 Length = (octets+1)*8/22, rounded up to integer
118 Service bits 6,7:
119 00 = rounding took less than 8/22ths
120 01 = rounding took 8/22...15/22ths
121 10 = rounding took 16/22ths or more.
122 f) 33 Mbit/s PBCC
123 Length = (octets+1)*8/33, rounded up to integer
124 Service bits 5,6,7:
125 000 rounding took less than 8/33
126 001 rounding took 8/33...15/33
127 010 rounding took 16/33...23/33
128 011 rounding took 24/33...31/33
129 100 rounding took 32/33 or more
130 2 bytes CRC
131
132 PSDU follows (up to 2346 bytes at selected rate)
133
134 While Signal value alone is not enough to determine rate and modulation,
135 Signal+Service is always sufficient.
136
137 Short preamble (at 1Mbit rate, takes 72 us):
138 7 bytes zeroes
139 2 bytes 0x05CF (lsb sent first)
140 PLCP header follows *at 2Mbit/s*. Format is the same as in long preamble.
141 PSDU follows (up to 2346 bytes at selected rate)
142
143 OFDM preamble is completely different, uses OFDM
144 modulation from the start and thus easily identifiable.
145 Not shown here.
