In addition, some of the functions also measures a matching level of a site. 74 The matching level is returned as a bit map. The select function 'OR's those bit maps in order to 75 select the site that has the biggest matching level. If a function returns a NO_MATCH value, the matching level of the 76 site is reset. 77 Following is the site matching level bit map structure. 78 Please notice, that if all the match functions returned MATCH for a site, its matric must be different than 0, 79 because of the rates bits. 80 81 82 31 - 24 23 - 20 20 - 16 15 - 10 9 - 8 7 6 5 4 - 0 83 +---------------+---------------+-----------------------+-------------+------------+----------+---------+-----------+-----------+ 84 | Rx Level | Privacy | Attempts |Rates | Modulation |Preamble | Channel | Spectrum | Reserved | 85 | | | | | | | | management| | 86 +---------------+---------------+-----------------------+-------------+------------+----------+---------+-----------+-----------+ 87 ****************************************************************************/ 88 89 /* Matric bit map definition */ 90 typedef enum 91 { 92 /* Rx level */ 93 METRIC_RX_LEVEL_MASK = 0xFF, 94 METRIC_RX_LEVEL_SHIFT = 24, 95 96 /* Privacy */ 97 METRIC_PRIVACY_MASK = 0x0F, 98 METRIC_PRIVACY_SHIFT = 20, 99 100 /* Number of attempts */ 101 METRIC_ATTEMPTS_NUMBER_MASK = 0x0F, 102 METRIC_ATTEMPTS_NUMBER_SHIFT = 16, 103 104 105 /* Rates */ 106 METRIC_RATES_MASK = 0x3F, 107 METRIC_RATES_SHIFT = 10, 108 109 /* PBCC */ 110 METRIC_MODULATION_MASK = 0x03, 111 METRIC_MODULATION_SHIFT = 8, 112 113 /* Preamble*/ 114 METRIC_PREAMBLE_MASK = 0x01, 115 METRIC_PREAMBLE_SHIFT = 7, 116 117 /* Channel */ 118 METRIC_CHANNEL_MASK = 0x01, 119 METRIC_CHANNEL_SHIFT = 6, 120 121 /* Spectrum management Capability */ 122 METRIC_SPECTRUM_MANAGEMENT_MASK = 0x01, 123 METRIC_SPECTRUM_MANAGEMENT_SHIFT= 5, 124 125 /* Priority Site */ 126 METRIC_PRIORITY_SITE_MASK = 0x01, 127 METRIC_PRIORITY_SITE_SHIFT = 4, 128 129 } matric_e;
