of Short Scrambled BSSID field The process starts by using the BSSID to generate the scrambled BSSID. The BSSID is divided into three words, (0 2), of 16 bits each, where is the 16 MSB of the BSSID and is the 16 LSB of the BSSID. wordi i word0 word2 ≤ ≤ For each a is created as follows: wordi, scrambled_wordi where: is the corresponding 16 bit word from the BSSID. wordi is ((0x5795×seed_value) mod 215), where is the value of the Scrambler scramble_pattern seed_value Initialization field in the L-Header of the PPDU carrying the Short SSW packet. The scrambled BSSID is generated by the consecutive concatenation of and scrambled_word0, scrambled_word1 scrambled_word2. Finally, the Short Scrambled BSSID field is generated by taking the 10 MSBs of CRC-16-CCITT computed over the scrambled BSSID. References: 11-15-1358-09-00ay-11ay Spec Framework
