| 503 | * information about any uCode error that occurs. For 4965, the format |
| 504 | * of the error log is: |
| 505 | * |
| 506 | * __le32 valid; (nonzero) valid, (0) log is empty |

| 1963 | * Tx rates and modulation modes (e.g. legacy/SISO/MIMO) for retrying Tx when |

| 1966 | * |
| 1967 | * NOTE: Station must already be in 4965's station table. Use REPLY_ADD_STA. |

| 1971 | * |
| 1972 | * |
| 1973 | * FILLING THE RATE TABLE |
| 1974 | * |
| 1975 | * Given a particular initial rate and mode, as determined by the rate |
| 1976 | * scaling algorithm described below, the Linux driver uses the following |
| 1977 | * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the |
| 1978 | * Link Quality command: |
| 1979 | * |
| 1980 | * |
| 1981 | * 1) If using High-throughput (HT) (SISO or MIMO) initial rate: |
| 1982 | * a) Use this same initial rate for first 3 entries. |
| 1983 | * b) Find next lower available rate using same mode (SISO or MIMO), |
| 1984 | * use for next 3 entries. If no lower rate available, switch to |
| 1985 | * legacy mode (no FAT channel, no MIMO, no short guard interval). |
| 1986 | * c) If using MIMO, set command's mimo_delimiter to number of entries |
| 1987 | * using MIMO (3 or 6). |
| 1988 | * d) After trying 2 HT rates, switch to legacy mode (no FAT channel, |
| 1989 | * no MIMO, no short guard interval), at the next lower bit rate |
| 1990 | * (e.g. if second HT bit rate was 54, try 48 legacy), and follow |
| 1991 | * legacy procedure for remaining table entries. |
| 1992 | * |
| 1993 | * 2) If using legacy initial rate: |
| 1994 | * a) Use the initial rate for only one entry. |
| 1995 | * b) For each following entry, reduce the rate to next lower available |
| 1996 | * rate, until reaching the lowest available rate. |
| 1997 | * c) When reducing rate, also switch antenna selection. |
| 1998 | * d) Once lowest available rate is reached, repeat this rate until |
| 1999 | * rate table is filled (16 entries), switching antenna each entry. |
| 2000 | * |
| 2001 | * |
| 2002 | * ACCUMULATING HISTORY |
| 2003 | * |
| 2004 | * The rate scaling algorithm for 4965, as implemented in Linux driver, uses |
| 2005 | * two sets of frame Tx success history: One for the current/active modulation |
| 2006 | * mode, and one for a speculative/search mode that is being attempted. If the |
| 2007 | * speculative mode turns out to be more effective (i.e. actual transfer |
| 2008 | * rate is better), then the driver continues to use the speculative mode |
| 2009 | * as the new current active mode. |
| 2010 | * |
| 2011 | * Each history set contains, separately for each possible rate, data for a |
| 2012 | * sliding window of the 62 most recent tx attempts at that rate. The data |
| 2013 | * includes a shifting bitmap of success(1)/failure(0), and sums of successful |
| 2014 | * and attempted frames, from which the driver can additionally calculate a |
| 2015 | * success ratio (success / attempted) and number of failures |
| 2016 | * (attempted - success), and control the size of the window (attempted). |
| 2017 | * The driver uses the bit map to remove successes from the success sum, as |
| 2018 | * the oldest tx attempts fall out of the window. |
| 2019 | * |
| 2020 | * When the 4965 makes multiple tx attempts for a given frame, each attempt |
| 2021 | * might be at a different rate, and have different modulation characteristics |
| 2022 | * (e.g. antenna, fat channel, short guard interval), as set up in the rate |
| 2023 | * scaling table in the Link Quality command. The driver must determine |
| 2024 | * which rate table entry was used for each tx attempt, to determine which |
| 2025 | * rate-specific history to update, and record only those attempts that |
| 2026 | * match the modulation characteristics of the history set. |
| 2027 | * |
| 2028 | * When using block-ack (aggregation), all frames are transmitted at the same |
Tomas Winkler | a96a27f | 2008-10-23 23:48:56 -0700 | [diff] [blame] | 2029 | * rate, since there is no per-attempt acknowledgment from the destination |
Ben Cahill | 2bdc703 | 2007-11-29 11:10:12 +0800 | [diff] [blame] | 2030 | * station. The Tx response struct iwl_tx_resp indicates the Tx rate in |
| 2031 | * rate_n_flags field. After receiving a block-ack, the driver can update |
| 2032 | * history for the entire block all at once. |
| 2033 | * |
| 2034 | * |
| 2035 | * FINDING BEST STARTING RATE: |
| 2036 | * |
| 2037 | * When working with a selected initial modulation mode (see below), the |
| 2038 | * driver attempts to find a best initial rate. The initial rate is the |
| 2039 | * first entry in the Link Quality command's rate table. |
| 2040 | * |
| 2041 | * 1) Calculate actual throughput (success ratio * expected throughput, see |
| 2042 | * table below) for current initial rate. Do this only if enough frames |
| 2043 | * have been attempted to make the value meaningful: at least 6 failed |
| 2044 | * tx attempts, or at least 8 successes. If not enough, don't try rate |
| 2045 | * scaling yet. |
| 2046 | * |
| 2047 | * 2) Find available rates adjacent to current initial rate. Available means: |
| 2048 | * a) supported by hardware && |
| 2049 | * b) supported by association && |
| 2050 | * c) within any constraints selected by user |
| 2051 | * |
| 2052 | * 3) Gather measured throughputs for adjacent rates. These might not have |
| 2053 | * enough history to calculate a throughput. That's okay, we might try |
| 2054 | * using one of them anyway! |
| 2055 | * |
| 2056 | * 4) Try decreasing rate if, for current rate: |
| 2057 | * a) success ratio is < 15% || |
| 2058 | * b) lower adjacent rate has better measured throughput || |
| 2059 | * c) higher adjacent rate has worse throughput, and lower is unmeasured |
| 2060 | * |
| 2061 | * As a sanity check, if decrease was determined above, leave rate |
| 2062 | * unchanged if: |
| 2063 | * a) lower rate unavailable |
| 2064 | * b) success ratio at current rate > 85% (very good) |
| 2065 | * c) current measured throughput is better than expected throughput |
| 2066 | * of lower rate (under perfect 100% tx conditions, see table below) |
| 2067 | * |
| 2068 | * 5) Try increasing rate if, for current rate: |
| 2069 | * a) success ratio is < 15% || |
| 2070 | * b) both adjacent rates' throughputs are unmeasured (try it!) || |
| 2071 | * b) higher adjacent rate has better measured throughput || |
| 2072 | * c) lower adjacent rate has worse throughput, and higher is unmeasured |
| 2073 | * |
| 2074 | * As a sanity check, if increase was determined above, leave rate |
| 2075 | * unchanged if: |
| 2076 | * a) success ratio at current rate < 70%. This is not particularly |
| 2077 | * good performance; higher rate is sure to have poorer success. |
| 2078 | * |
| 2079 | * 6) Re-evaluate the rate after each tx frame. If working with block- |
| 2080 | * acknowledge, history and statistics may be calculated for the entire |
| 2081 | * block (including prior history that fits within the history windows), |
| 2082 | * before re-evaluation. |
| 2083 | * |
| 2084 | * FINDING BEST STARTING MODULATION MODE: |
| 2085 | * |
| 2086 | * After working with a modulation mode for a "while" (and doing rate scaling), |
| 2087 | * the driver searches for a new initial mode in an attempt to improve |
| 2088 | * throughput. The "while" is measured by numbers of attempted frames: |
| 2089 | * |
| 2090 | * For legacy mode, search for new mode after: |
| 2091 | * 480 successful frames, or 160 failed frames |
| 2092 | * For high-throughput modes (SISO or MIMO), search for new mode after: |
| 2093 | * 4500 successful frames, or 400 failed frames |
| 2094 | * |
| 2095 | * Mode switch possibilities are (3 for each mode): |
| 2096 | * |
| 2097 | * For legacy: |
| 2098 | * Change antenna, try SISO (if HT association), try MIMO (if HT association) |
| 2099 | * For SISO: |
| 2100 | * Change antenna, try MIMO, try shortened guard interval (SGI) |
| 2101 | * For MIMO: |
| 2102 | * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) |
| 2103 | * |
| 2104 | * When trying a new mode, use the same bit rate as the old/current mode when |
| 2105 | * trying antenna switches and shortened guard interval. When switching to |
| 2106 | * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate |
| 2107 | * for which the expected throughput (under perfect conditions) is about the |
| 2108 | * same or slightly better than the actual measured throughput delivered by |
| 2109 | * the old/current mode. |
| 2110 | * |
| 2111 | * Actual throughput can be estimated by multiplying the expected throughput |
| 2112 | * by the success ratio (successful / attempted tx frames). Frame size is |
| 2113 | * not considered in this calculation; it assumes that frame size will average |
| 2114 | * out to be fairly consistent over several samples. The following are |
| 2115 | * metric values for expected throughput assuming 100% success ratio. |
| 2116 | * Only G band has support for CCK rates: |
| 2117 | * |
| 2118 | * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60 |
| 2119 | * |
| 2120 | * G: 7 13 35 58 40 57 72 98 121 154 177 186 186 |
| 2121 | * A: 0 0 0 0 40 57 72 98 121 154 177 186 186 |
| 2122 | * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202 |
| 2123 | * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211 |
| 2124 | * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251 |
| 2125 | * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257 |
| 2126 | * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257 |
| 2127 | * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264 |
| 2128 | * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289 |
| 2129 | * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293 |
| 2130 | * |
| 2131 | * After the new mode has been tried for a short while (minimum of 6 failed |
| 2132 | * frames or 8 successful frames), compare success ratio and actual throughput |
| 2133 | * estimate of the new mode with the old. If either is better with the new |
| 2134 | * mode, continue to use the new mode. |
| 2135 | * |
| 2136 | * Continue comparing modes until all 3 possibilities have been tried. |
| 2137 | * If moving from legacy to HT, try all 3 possibilities from the new HT |
| 2138 | * mode. After trying all 3, a best mode is found. Continue to use this mode |
| 2139 | * for the longer "while" described above (e.g. 480 successful frames for |
| 2140 | * legacy), and then repeat the search process. |

| 2504 | * The hardware scan command is very powerful; the driver can set it up to |
| 2505 | * maintain (relatively) normal network traffic while doing a scan in the |
| 2506 | * background. The max_out_time and suspend_time control the ratio of how |
| 2507 | * long the device stays on an associated network channel ("service channel") |
| 2508 | * vs. how long it's away from the service channel, i.e. tuned to other channels |
| 2509 | * for scanning. |
| 2510 | * |
| 2511 | * max_out_time is the max time off-channel (in usec), and suspend_time |
| 2512 | * is how long (in "extended beacon" format) that the scan is "suspended" |
| 2513 | * after returning to the service channel. That is, suspend_time is the |
| 2514 | * time that we stay on the service channel, doing normal work, between |
| 2515 | * scan segments. The driver may set these parameters differently to support |
| 2516 | * scanning when associated vs. not associated, and light vs. heavy traffic |
| 2517 | * loads when associated. |
| 2518 | * |
| 2519 | * After receiving this command, the device's scan engine does the following; |
| 2520 | * |
| 2521 | * 1) Sends SCAN_START notification to driver |
| 2522 | * 2) Checks to see if it has time to do scan for one channel |
| 2523 | * 3) Sends NULL packet, with power-save (PS) bit set to 1, |
| 2524 | * to tell AP that we're going off-channel |
| 2525 | * 4) Tunes to first channel in scan list, does active or passive scan |
| 2526 | * 5) Sends SCAN_RESULT notification to driver |
| 2527 | * 6) Checks to see if it has time to do scan on *next* channel in list |
| 2528 | * 7) Repeats 4-6 until it no longer has time to scan the next channel |
| 2529 | * before max_out_time expires |
| 2530 | * 8) Returns to service channel |
| 2531 | * 9) Sends NULL packet with PS=0 to tell AP that we're back |
| 2532 | * 10) Stays on service channel until suspend_time expires |
| 2533 | * 11) Repeats entire process 2-10 until list is complete |
| 2534 | * 12) Sends SCAN_COMPLETE notification |
| 2535 | * |
| 2536 | * For fast, efficient scans, the scan command also has support for staying on |
| 2537 | * a channel for just a short time, if doing active scanning and getting no |
| 2538 | * responses to the transmitted probe request. This time is controlled by |
| 2539 | * quiet_time, and the number of received packets below which a channel is |
| 2540 | * considered "quiet" is controlled by quiet_plcp_threshold. |
| 2541 | * |
| 2542 | * For active scanning on channels that have regulatory restrictions against |
| 2543 | * blindly transmitting, the scan can listen before transmitting, to make sure |
| 2544 | * that there is already legitimate activity on the channel. If enough |
| 2545 | * packets are cleanly received on the channel (controlled by good_CRC_th, |
| 2546 | * typical value 1), the scan engine starts transmitting probe requests. |
| 2547 | * |
| 2548 | * Driver must use separate scan commands for 2.4 vs. 5 GHz bands. |
| 2549 | * |
| 2550 | * To avoid uCode errors, see timing restrictions described under |

| 3058 | * SENSITIVITY_CMD = 0xa8 (command, has simple generic response) |
| 3059 | * |
| 3060 | * This command sets up the Rx signal detector for a sensitivity level that |
| 3061 | * is high enough to lock onto all signals within the associated network, |
| 3062 | * but low enough to ignore signals that are below a certain threshold, so as |
| 3063 | * not to have too many "false alarms". False alarms are signals that the |
| 3064 | * Rx DSP tries to lock onto, but then discards after determining that they |
| 3065 | * are noise. |
| 3066 | * |
| 3067 | * The optimum number of false alarms is between 5 and 50 per 200 TUs |
| 3068 | * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e. |
| 3069 | * time listening, not transmitting). Driver must adjust sensitivity so that |
| 3070 | * the ratio of actual false alarms to actual Rx time falls within this range. |
| 3071 | * |
| 3072 | * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each |
| 3073 | * received beacon. These provide information to the driver to analyze the |
| 3074 | * sensitivity. Don't analyze statistics that come in from scanning, or any |
| 3075 | * other non-associated-network source. Pertinent statistics include: |
| 3076 | * |
| 3077 | * From "general" statistics (struct statistics_rx_non_phy): |
| 3078 | * |
| 3079 | * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level) |
| 3080 | * Measure of energy of desired signal. Used for establishing a level |
| 3081 | * below which the device does not detect signals. |
| 3082 | * |
| 3083 | * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB) |
| 3084 | * Measure of background noise in silent period after beacon. |
| 3085 | * |
| 3086 | * channel_load |
| 3087 | * uSecs of actual Rx time during beacon period (varies according to |
| 3088 | * how much time was spent transmitting). |
| 3089 | * |
| 3090 | * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately: |
| 3091 | * |
| 3092 | * false_alarm_cnt |
| 3093 | * Signal locks abandoned early (before phy-level header). |
| 3094 | * |
| 3095 | * plcp_err |
| 3096 | * Signal locks abandoned late (during phy-level header). |
| 3097 | * |
| 3098 | * NOTE: Both false_alarm_cnt and plcp_err increment monotonically from |
| 3099 | * beacon to beacon, i.e. each value is an accumulation of all errors |
| 3100 | * before and including the latest beacon. Values will wrap around to 0 |
| 3101 | * after counting up to 2^32 - 1. Driver must differentiate vs. |
| 3102 | * previous beacon's values to determine # false alarms in the current |
| 3103 | * beacon period. |
| 3104 | * |
| 3105 | * Total number of false alarms = false_alarms + plcp_errs |
| 3106 | * |
| 3107 | * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd |
| 3108 | * (notice that the start points for OFDM are at or close to settings for |
| 3109 | * maximum sensitivity): |
| 3110 | * |
| 3111 | * START / MIN / MAX |
| 3112 | * HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120 |
| 3113 | * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210 |
| 3114 | * HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140 |
| 3115 | * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270 |
| 3116 | * |
| 3117 | * If actual rate of OFDM false alarms (+ plcp_errors) is too high |
| 3118 | * (greater than 50 for each 204.8 msecs listening), reduce sensitivity |
| 3119 | * by *adding* 1 to all 4 of the table entries above, up to the max for |
| 3120 | * each entry. Conversely, if false alarm rate is too low (less than 5 |
| 3121 | * for each 204.8 msecs listening), *subtract* 1 from each entry to |
| 3122 | * increase sensitivity. |
| 3123 | * |
| 3124 | * For CCK sensitivity, keep track of the following: |
| 3125 | * |
| 3126 | * 1). 20-beacon history of maximum background noise, indicated by |
| 3127 | * (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the |
| 3128 | * 3 receivers. For any given beacon, the "silence reference" is |
| 3129 | * the maximum of last 60 samples (20 beacons * 3 receivers). |
| 3130 | * |
| 3131 | * 2). 10-beacon history of strongest signal level, as indicated |
| 3132 | * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers, |
| 3133 | * i.e. the strength of the signal through the best receiver at the |
| 3134 | * moment. These measurements are "upside down", with lower values |
| 3135 | * for stronger signals, so max energy will be *minimum* value. |
| 3136 | * |
| 3137 | * Then for any given beacon, the driver must determine the *weakest* |
| 3138 | * of the strongest signals; this is the minimum level that needs to be |
| 3139 | * successfully detected, when using the best receiver at the moment. |
| 3140 | * "Max cck energy" is the maximum (higher value means lower energy!) |
| 3141 | * of the last 10 minima. Once this is determined, driver must add |
| 3142 | * a little margin by adding "6" to it. |
| 3143 | * |
| 3144 | * 3). Number of consecutive beacon periods with too few false alarms. |
| 3145 | * Reset this to 0 at the first beacon period that falls within the |
| 3146 | * "good" range (5 to 50 false alarms per 204.8 milliseconds rx). |
| 3147 | * |
| 3148 | * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd |
| 3149 | * (notice that the start points for CCK are at maximum sensitivity): |
| 3150 | * |
| 3151 | * START / MIN / MAX |
| 3152 | * HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200 |
| 3153 | * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400 |
| 3154 | * HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100 |
| 3155 | * |
| 3156 | * If actual rate of CCK false alarms (+ plcp_errors) is too high |
| 3157 | * (greater than 50 for each 204.8 msecs listening), method for reducing |
| 3158 | * sensitivity is: |
| 3159 | * |
| 3160 | * 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX, |
| 3161 | * up to max 400. |
| 3162 | * |
| 3163 | * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160, |
| 3164 | * sensitivity has been reduced a significant amount; bring it up to |
| 3165 | * a moderate 161. Otherwise, *add* 3, up to max 200. |
| 3166 | * |
| 3167 | * 3) a) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160, |
| 3168 | * sensitivity has been reduced only a moderate or small amount; |
| 3169 | * *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX, |
| 3170 | * down to min 0. Otherwise (if gain has been significantly reduced), |
| 3171 | * don't change the HD_MIN_ENERGY_CCK_DET_INDEX value. |
| 3172 | * |
| 3173 | * b) Save a snapshot of the "silence reference". |
| 3174 | * |
| 3175 | * If actual rate of CCK false alarms (+ plcp_errors) is too low |
| 3176 | * (less than 5 for each 204.8 msecs listening), method for increasing |
| 3177 | * sensitivity is used only if: |
| 3178 | * |
| 3179 | * 1a) Previous beacon did not have too many false alarms |
| 3180 | * 1b) AND difference between previous "silence reference" and current |
| 3181 | * "silence reference" (prev - current) is 2 or more, |
| 3182 | * OR 2) 100 or more consecutive beacon periods have had rate of |
| 3183 | * less than 5 false alarms per 204.8 milliseconds rx time. |
| 3184 | * |
| 3185 | * Method for increasing sensitivity: |
| 3186 | * |
| 3187 | * 1) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX, |
| 3188 | * down to min 125. |
| 3189 | * |
| 3190 | * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX, |
| 3191 | * down to min 200. |
| 3192 | * |
| 3193 | * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100. |
| 3194 | * |
| 3195 | * If actual rate of CCK false alarms (+ plcp_errors) is within good range |
| 3196 | * (between 5 and 50 for each 204.8 msecs listening): |
| 3197 | * |
| 3198 | * 1) Save a snapshot of the silence reference. |
| 3199 | * |
| 3200 | * 2) If previous beacon had too many CCK false alarms (+ plcp_errors), |
| 3201 | * give some extra margin to energy threshold by *subtracting* 8 |
| 3202 | * from value in HD_MIN_ENERGY_CCK_DET_INDEX. |
| 3203 | * |
| 3204 | * For all cases (too few, too many, good range), make sure that the CCK |
| 3205 | * detection threshold (energy) is below the energy level for robust |
| 3206 | * detection over the past 10 beacon periods, the "Max cck energy". |
| 3207 | * Lower values mean higher energy; this means making sure that the value |
| 3208 | * in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy". |
| 3209 | * |
| 3210 | * Driver should set the following entries to fixed values: |
| 3211 | * |
| 3212 | * HD_MIN_ENERGY_OFDM_DET_INDEX 100 |
| 3213 | * HD_BARKER_CORR_TH_ADD_MIN_INDEX 190 |
| 3214 | * HD_BARKER_CORR_TH_ADD_MIN_MRC_INDEX 390 |
| 3215 | * HD_OFDM_ENERGY_TH_IN_INDEX 62 |

| 3255 | * |
| 3256 | * After the first association, driver should accumulate signal and noise |

| 3260 | * |
| 3261 | * DISCONNECTED ANTENNA: |

| 3277 | * |
| 3278 | * |
| 3279 | * RX BALANCE: |

| 3281 | * Driver should balance the 3 receivers (but just the ones that are connected |
| 3282 | * to antennas, see above) for gain, by comparing the average signal levels |

| 3284 | * Accumulate (add) the following values over 20 beacons, one accumulator for |

| 3288 | * |
| 3289 | * Find the weakest background noise level from among a/b/c. This Rx chain |
