1082 | * The device contains an internal table of per-station information, | |
1083 | * with info on security keys, aggregation parameters, and Tx rates for | |
767d055d WYG |
1084 | * initial Tx attempt and any retries (agn devices uses |
1085 | * REPLY_TX_LINK_QUALITY_CMD, | |
2054a00b BC |
1086 | * 3945 uses REPLY_RATE_SCALE to set up rate tables). |
1087 | * | |
1088 | * REPLY_ADD_STA sets up the table entry for one station, either creating | |
1089 | * a new entry, or modifying a pre-existing one. | |
1090 | * | |
1091 | * NOTE: RXON command (without "associated" bit set) wipes the station table | |
1092 | * clean. Moving into RF_KILL state does this also. Driver must set up | |
1093 | * new station table before transmitting anything on the RXON channel | |
1094 | * (except active scans or active measurements; those commands carry | |
1095 | * their own txpower/rate setup data). | |
1096 | * | |
1097 | * When getting started on a new channel, driver must set up the | |
1098 | * IWL_BROADCAST_ID entry (last entry in the table). For a client | |
1099 | * station in a BSS, once an AP is selected, driver sets up the AP STA | |
1100 | * in the IWL_AP_ID entry (1st entry in the table). BROADCAST and AP | |
1101 | * are all that are needed for a BSS client station. If the device is | |
1102 | * used as AP, or in an IBSS network, driver must set up station table | |
1103 | * entries for all STAs in network, starting with index IWL_STA_ID. | |

1444 | * Tx Commands & Responses: | |

52969981 BC |
1446 | * Driver must place each REPLY_TX command into one of the prioritized Tx |
1447 | * queues in host DRAM, shared between driver and device (see comments for | |
1448 | * SCD registers and Tx/Rx Queues). When the device's Tx scheduler and uCode | |
1449 | * are preparing to transmit, the device pulls the Tx command over the PCI | |
1450 | * bus via one of the device's Tx DMA channels, to fill an internal FIFO | |
1451 | * from which data will be transmitted. | |
1452 | * | |
1453 | * uCode handles all timing and protocol related to control frames | |
1454 | * (RTS/CTS/ACK), based on flags in the Tx command. uCode and Tx scheduler | |
1455 | * handle reception of block-acks; uCode updates the host driver via | |
767d055d | 1456 | * REPLY_COMPRESSED_BA. |
52969981 BC |
1457 | * |
1458 | * uCode handles retrying Tx when an ACK is expected but not received. | |
1459 | * This includes trying lower data rates than the one requested in the Tx | |
1460 | * command, as set up by the REPLY_RATE_SCALE (for 3945) or | |
767d055d | 1461 | * REPLY_TX_LINK_QUALITY_CMD (agn). |
52969981 BC |
1462 | * |
1463 | * Driver sets up transmit power for various rates via REPLY_TX_PWR_TABLE_CMD. | |
1464 | * This command must be executed after every RXON command, before Tx can occur. | |

2186 | * FILLING THE RATE TABLE | |
2187 | * | |
2188 | * Given a particular initial rate and mode, as determined by the rate | |
2189 | * scaling algorithm described below, the Linux driver uses the following | |
2190 | * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the | |
2191 | * Link Quality command: | |
2192 | * | |
2193 | * | |
2194 | * 1) If using High-throughput (HT) (SISO or MIMO) initial rate: | |
2195 | * a) Use this same initial rate for first 3 entries. | |
2196 | * b) Find next lower available rate using same mode (SISO or MIMO), | |
2197 | * use for next 3 entries. If no lower rate available, switch to | |
7aafef1c | 2198 | * legacy mode (no HT40 channel, no MIMO, no short guard interval). |
2bdc7031 BC |
2199 | * c) If using MIMO, set command's mimo_delimiter to number of entries |
2200 | * using MIMO (3 or 6). | |
7aafef1c | 2201 | * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, |
2bdc7031 BC |
2202 | * no MIMO, no short guard interval), at the next lower bit rate |
2203 | * (e.g. if second HT bit rate was 54, try 48 legacy), and follow | |
2204 | * legacy procedure for remaining table entries. | |
2205 | * | |
2206 | * 2) If using legacy initial rate: | |
2207 | * a) Use the initial rate for only one entry. | |
2208 | * b) For each following entry, reduce the rate to next lower available | |
2209 | * rate, until reaching the lowest available rate. | |
2210 | * c) When reducing rate, also switch antenna selection. | |
2211 | * d) Once lowest available rate is reached, repeat this rate until | |
2212 | * rate table is filled (16 entries), switching antenna each entry. | |
2213 | * | |
2214 | * | |
2215 | * ACCUMULATING HISTORY | |
2216 | * | |
767d055d WYG |
2217 | * The rate scaling algorithm for agn devices, as implemented in Linux driver, |
2218 | * uses two sets of frame Tx success history: One for the current/active | |
2219 | * modulation mode, and one for a speculative/search mode that is being | |
2220 | * attempted. If the speculative mode turns out to be more effective (i.e. | |
2221 | * actual transfer rate is better), then the driver continues to use the | |
2222 | * speculative mode as the new current active mode. | |
2bdc7031 BC |
2223 | * |
2224 | * Each history set contains, separately for each possible rate, data for a | |
2225 | * sliding window of the 62 most recent tx attempts at that rate. The data | |
2226 | * includes a shifting bitmap of success(1)/failure(0), and sums of successful | |
2227 | * and attempted frames, from which the driver can additionally calculate a | |
2228 | * success ratio (success / attempted) and number of failures | |
2229 | * (attempted - success), and control the size of the window (attempted). | |
2230 | * The driver uses the bit map to remove successes from the success sum, as | |
2231 | * the oldest tx attempts fall out of the window. | |
2232 | * | |
767d055d WYG |
2233 | * When the agn device makes multiple tx attempts for a given frame, each |
2234 | * attempt might be at a different rate, and have different modulation | |
2235 | * characteristics (e.g. antenna, fat channel, short guard interval), as set | |
2236 | * up in the rate scaling table in the Link Quality command. The driver must | |
2237 | * determine which rate table entry was used for each tx attempt, to determine | |
2238 | * which rate-specific history to update, and record only those attempts that | |
2bdc7031 BC |
2239 | * match the modulation characteristics of the history set. |
2240 | * | |
2241 | * When using block-ack (aggregation), all frames are transmitted at the same | |
a96a27f9 | 2242 | * rate, since there is no per-attempt acknowledgment from the destination |
2bdc7031 BC |
2243 | * station. The Tx response struct iwl_tx_resp indicates the Tx rate in |
2244 | * rate_n_flags field. After receiving a block-ack, the driver can update | |
2245 | * history for the entire block all at once. | |
2246 | * | |
2247 | * | |
2248 | * FINDING BEST STARTING RATE: | |
2249 | * | |
2250 | * When working with a selected initial modulation mode (see below), the | |
2251 | * driver attempts to find a best initial rate. The initial rate is the | |
2252 | * first entry in the Link Quality command's rate table. | |
2253 | * | |
2254 | * 1) Calculate actual throughput (success ratio * expected throughput, see | |
2255 | * table below) for current initial rate. Do this only if enough frames | |
2256 | * have been attempted to make the value meaningful: at least 6 failed | |
2257 | * tx attempts, or at least 8 successes. If not enough, don't try rate | |
2258 | * scaling yet. | |
2259 | * | |
2260 | * 2) Find available rates adjacent to current initial rate. Available means: | |
2261 | * a) supported by hardware && | |
2262 | * b) supported by association && | |
2263 | * c) within any constraints selected by user | |
2264 | * | |
2265 | * 3) Gather measured throughputs for adjacent rates. These might not have | |
2266 | * enough history to calculate a throughput. That's okay, we might try | |
2267 | * using one of them anyway! | |
2268 | * | |
2269 | * 4) Try decreasing rate if, for current rate: | |
2270 | * a) success ratio is < 15% || | |
2271 | * b) lower adjacent rate has better measured throughput || | |
2272 | * c) higher adjacent rate has worse throughput, and lower is unmeasured | |
2273 | * | |
2274 | * As a sanity check, if decrease was determined above, leave rate | |
2275 | * unchanged if: | |
2276 | * a) lower rate unavailable | |
2277 | * b) success ratio at current rate > 85% (very good) | |
2278 | * c) current measured throughput is better than expected throughput | |
2279 | * of lower rate (under perfect 100% tx conditions, see table below) | |
2280 | * | |
2281 | * 5) Try increasing rate if, for current rate: | |
2282 | * a) success ratio is < 15% || | |
2283 | * b) both adjacent rates' throughputs are unmeasured (try it!) || | |
2284 | * b) higher adjacent rate has better measured throughput || | |
2285 | * c) lower adjacent rate has worse throughput, and higher is unmeasured | |
2286 | * | |
2287 | * As a sanity check, if increase was determined above, leave rate | |
2288 | * unchanged if: | |
2289 | * a) success ratio at current rate < 70%. This is not particularly | |
2290 | * good performance; higher rate is sure to have poorer success. | |
2291 | * | |
2292 | * 6) Re-evaluate the rate after each tx frame. If working with block- | |
2293 | * acknowledge, history and statistics may be calculated for the entire | |
2294 | * block (including prior history that fits within the history windows), | |
2295 | * before re-evaluation. | |
2296 | * | |
2297 | * FINDING BEST STARTING MODULATION MODE: | |
2298 | * | |
2299 | * After working with a modulation mode for a "while" (and doing rate scaling), | |
2300 | * the driver searches for a new initial mode in an attempt to improve | |
2301 | * throughput. The "while" is measured by numbers of attempted frames: | |
2302 | * | |
2303 | * For legacy mode, search for new mode after: | |
2304 | * 480 successful frames, or 160 failed frames | |
2305 | * For high-throughput modes (SISO or MIMO), search for new mode after: | |
2306 | * 4500 successful frames, or 400 failed frames | |
2307 | * | |
2308 | * Mode switch possibilities are (3 for each mode): | |
2309 | * | |
2310 | * For legacy: | |
2311 | * Change antenna, try SISO (if HT association), try MIMO (if HT association) | |
2312 | * For SISO: | |
2313 | * Change antenna, try MIMO, try shortened guard interval (SGI) | |
2314 | * For MIMO: | |
2315 | * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) | |
2316 | * | |
2317 | * When trying a new mode, use the same bit rate as the old/current mode when | |
2318 | * trying antenna switches and shortened guard interval. When switching to | |
2319 | * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate | |
2320 | * for which the expected throughput (under perfect conditions) is about the | |
2321 | * same or slightly better than the actual measured throughput delivered by | |
2322 | * the old/current mode. | |
2323 | * | |
2324 | * Actual throughput can be estimated by multiplying the expected throughput | |
2325 | * by the success ratio (successful / attempted tx frames). Frame size is | |
2326 | * not considered in this calculation; it assumes that frame size will average | |
2327 | * out to be fairly consistent over several samples. The following are | |
2328 | * metric values for expected throughput assuming 100% success ratio. | |
2329 | * Only G band has support for CCK rates: | |
2330 | * | |
2331 | * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60 | |
2332 | * | |
2333 | * G: 7 13 35 58 40 57 72 98 121 154 177 186 186 | |
2334 | * A: 0 0 0 0 40 57 72 98 121 154 177 186 186 | |
2335 | * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202 | |
2336 | * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211 | |
2337 | * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251 | |
2338 | * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257 | |
2339 | * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257 | |
2340 | * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264 | |
2341 | * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289 | |
2342 | * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293 | |
2343 | * | |
2344 | * After the new mode has been tried for a short while (minimum of 6 failed | |
2345 | * frames or 8 successful frames), compare success ratio and actual throughput | |
2346 | * estimate of the new mode with the old. If either is better with the new | |
2347 | * mode, continue to use the new mode. | |
2348 | * | |
2349 | * Continue comparing modes until all 3 possibilities have been tried. | |
2350 | * If moving from legacy to HT, try all 3 possibilities from the new HT | |
2351 | * mode. After trying all 3, a best mode is found. Continue to use this mode | |
2352 | * for the longer "while" described above (e.g. 480 successful frames for | |
2353 | * legacy), and then repeat the search process. | |

2855 | * REPLY_SCAN_CMD = 0x80 (command) | |
3058f021 BC |
2856 | * |
2857 | * The hardware scan command is very powerful; the driver can set it up to | |
2858 | * maintain (relatively) normal network traffic while doing a scan in the | |
2859 | * background. The max_out_time and suspend_time control the ratio of how | |
2860 | * long the device stays on an associated network channel ("service channel") | |
2861 | * vs. how long it's away from the service channel, i.e. tuned to other channels | |
2862 | * for scanning. | |
2863 | * | |
2864 | * max_out_time is the max time off-channel (in usec), and suspend_time | |
2865 | * is how long (in "extended beacon" format) that the scan is "suspended" | |
2866 | * after returning to the service channel. That is, suspend_time is the | |
2867 | * time that we stay on the service channel, doing normal work, between | |
2868 | * scan segments. The driver may set these parameters differently to support | |
2869 | * scanning when associated vs. not associated, and light vs. heavy traffic | |
2870 | * loads when associated. | |
2871 | * | |
2872 | * After receiving this command, the device's scan engine does the following; | |
2873 | * | |
2874 | * 1) Sends SCAN_START notification to driver | |
2875 | * 2) Checks to see if it has time to do scan for one channel | |
2876 | * 3) Sends NULL packet, with power-save (PS) bit set to 1, | |
2877 | * to tell AP that we're going off-channel | |
2878 | * 4) Tunes to first channel in scan list, does active or passive scan | |
2879 | * 5) Sends SCAN_RESULT notification to driver | |
2880 | * 6) Checks to see if it has time to do scan on *next* channel in list | |
2881 | * 7) Repeats 4-6 until it no longer has time to scan the next channel | |
2882 | * before max_out_time expires | |
2883 | * 8) Returns to service channel | |
2884 | * 9) Sends NULL packet with PS=0 to tell AP that we're back | |
2885 | * 10) Stays on service channel until suspend_time expires | |
2886 | * 11) Repeats entire process 2-10 until list is complete | |
2887 | * 12) Sends SCAN_COMPLETE notification | |
2888 | * | |
2889 | * For fast, efficient scans, the scan command also has support for staying on | |
2890 | * a channel for just a short time, if doing active scanning and getting no | |
2891 | * responses to the transmitted probe request. This time is controlled by | |
2892 | * quiet_time, and the number of received packets below which a channel is | |
2893 | * considered "quiet" is controlled by quiet_plcp_threshold. | |
2894 | * | |
2895 | * For active scanning on channels that have regulatory restrictions against | |
2896 | * blindly transmitting, the scan can listen before transmitting, to make sure | |
2897 | * that there is already legitimate activity on the channel. If enough | |
2898 | * packets are cleanly received on the channel (controlled by good_CRC_th, | |
2899 | * typical value 1), the scan engine starts transmitting probe requests. | |
2900 | * | |
2901 | * Driver must use separate scan commands for 2.4 vs. 5 GHz bands. | |
2902 | * | |
2903 | * To avoid uCode errors, see timing restrictions described under | |
2a421b91 | 2904 | * struct iwl_scan_channel. |

3513 | * SENSITIVITY_CMD = 0xa8 (command, has simple generic response) | |
3514 | * | |
3515 | * This command sets up the Rx signal detector for a sensitivity level that | |
3516 | * is high enough to lock onto all signals within the associated network, | |
3517 | * but low enough to ignore signals that are below a certain threshold, so as | |
3518 | * not to have too many "false alarms". False alarms are signals that the | |
3519 | * Rx DSP tries to lock onto, but then discards after determining that they | |
3520 | * are noise. | |
3521 | * | |
3522 | * The optimum number of false alarms is between 5 and 50 per 200 TUs | |
3523 | * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e. | |
3524 | * time listening, not transmitting). Driver must adjust sensitivity so that | |
3525 | * the ratio of actual false alarms to actual Rx time falls within this range. | |
3526 | * | |
3527 | * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each | |
3528 | * received beacon. These provide information to the driver to analyze the | |
3529 | * sensitivity. Don't analyze statistics that come in from scanning, or any | |
3530 | * other non-associated-network source. Pertinent statistics include: | |
3531 | * | |
3532 | * From "general" statistics (struct statistics_rx_non_phy): | |
3533 | * | |
3534 | * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level) | |
3535 | * Measure of energy of desired signal. Used for establishing a level | |
3536 | * below which the device does not detect signals. | |
3537 | * | |
3538 | * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB) | |
3539 | * Measure of background noise in silent period after beacon. | |
3540 | * | |
3541 | * channel_load | |
3542 | * uSecs of actual Rx time during beacon period (varies according to | |
3543 | * how much time was spent transmitting). | |
3544 | * | |
3545 | * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately: | |

3547 | * false_alarm_cnt | |
3548 | * Signal locks abandoned early (before phy-level header). | |

3550 | * plcp_err | |
3551 | * Signal locks abandoned late (during phy-level header). | |
3552 | * | |
3553 | * NOTE: Both false_alarm_cnt and plcp_err increment monotonically from | |
3554 | * beacon to beacon, i.e. each value is an accumulation of all errors | |
3555 | * before and including the latest beacon. Values will wrap around to 0 | |
3556 | * after counting up to 2^32 - 1. Driver must differentiate vs. | |
3557 | * previous beacon's values to determine # false alarms in the current | |
3558 | * beacon period. | |
3559 | * | |
3560 | * Total number of false alarms = false_alarms + plcp_errs | |
3561 | * | |
3562 | * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd | |
3563 | * (notice that the start points for OFDM are at or close to settings for | |
3564 | * maximum sensitivity): | |
3565 | * | |
3566 | * START / MIN / MAX | |
3567 | * HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120 | |
3568 | * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210 | |
3569 | * HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140 | |
3570 | * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270 | |
3571 | * | |
3572 | * If actual rate of OFDM false alarms (+ plcp_errors) is too high | |
3573 | * (greater than 50 for each 204.8 msecs listening), reduce sensitivity | |
3574 | * by *adding* 1 to all 4 of the table entries above, up to the max for | |
3575 | * each entry. Conversely, if false alarm rate is too low (less than 5 | |
3576 | * for each 204.8 msecs listening), *subtract* 1 from each entry to | |
3577 | * increase sensitivity. | |
3578 | * | |
3579 | * For CCK sensitivity, keep track of the following: | |
3580 | * | |
3581 | * 1). 20-beacon history of maximum background noise, indicated by | |
3582 | * (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the | |
3583 | * 3 receivers. For any given beacon, the "silence reference" is | |
3584 | * the maximum of last 60 samples (20 beacons * 3 receivers). | |
3585 | * | |
3586 | * 2). 10-beacon history of strongest signal level, as indicated | |
3587 | * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers, | |
3588 | * i.e. the strength of the signal through the best receiver at the | |
3589 | * moment. These measurements are "upside down", with lower values | |
3590 | * for stronger signals, so max energy will be *minimum* value. | |
3591 | * | |
3592 | * Then for any given beacon, the driver must determine the *weakest* | |
3593 | * of the strongest signals; this is the minimum level that needs to be | |
3594 | * successfully detected, when using the best receiver at the moment. | |
3595 | * "Max cck energy" is the maximum (higher value means lower energy!) | |
3596 | * of the last 10 minima. Once this is determined, driver must add | |
3597 | * a little margin by adding "6" to it. | |
3598 | * | |
3599 | * 3). Number of consecutive beacon periods with too few false alarms. | |
3600 | * Reset this to 0 at the first beacon period that falls within the | |
3601 | * "good" range (5 to 50 false alarms per 204.8 milliseconds rx). | |
3602 | * | |
3603 | * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd | |
3604 | * (notice that the start points for CCK are at maximum sensitivity): | |
3605 | * | |
3606 | * START / MIN / MAX | |
3607 | * HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200 | |
3608 | * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400 | |
3609 | * HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100 | |
3610 | * | |
3611 | * If actual rate of CCK false alarms (+ plcp_errors) is too high | |
3612 | * (greater than 50 for each 204.8 msecs listening), method for reducing | |
3613 | * sensitivity is: | |
3614 | * | |
3615 | * 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX, | |
3616 | * up to max 400. | |
3617 | * | |
3618 | * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160, | |
3619 | * sensitivity has been reduced a significant amount; bring it up to | |
3620 | * a moderate 161. Otherwise, *add* 3, up to max 200. | |
3621 | * | |
3622 | * 3) a) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160, | |
3623 | * sensitivity has been reduced only a moderate or small amount; | |
3624 | * *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX, | |
3625 | * down to min 0. Otherwise (if gain has been significantly reduced), | |
3626 | * don't change the HD_MIN_ENERGY_CCK_DET_INDEX value. | |
3627 | * | |
3628 | * b) Save a snapshot of the "silence reference". | |
3629 | * | |
3630 | * If actual rate of CCK false alarms (+ plcp_errors) is too low | |
3631 | * (less than 5 for each 204.8 msecs listening), method for increasing | |
3632 | * sensitivity is used only if: | |
3633 | * | |
3634 | * 1a) Previous beacon did not have too many false alarms | |
3635 | * 1b) AND difference between previous "silence reference" and current | |
3636 | * "silence reference" (prev - current) is 2 or more, | |
3637 | * OR 2) 100 or more consecutive beacon periods have had rate of | |
3638 | * less than 5 false alarms per 204.8 milliseconds rx time. | |
3639 | * | |
3640 | * Method for increasing sensitivity: | |
3641 | * | |
3642 | * 1) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX, | |
3643 | * down to min 125. | |
3644 | * | |
3645 | * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX, | |
3646 | * down to min 200. | |
3647 | * | |
3648 | * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100. | |
3649 | * | |
3650 | * If actual rate of CCK false alarms (+ plcp_errors) is within good range | |
3651 | * (between 5 and 50 for each 204.8 msecs listening): | |
3652 | * | |
3653 | * 1) Save a snapshot of the silence reference. | |
3654 | * | |
3655 | * 2) If previous beacon had too many CCK false alarms (+ plcp_errors), | |
3656 | * give some extra margin to energy threshold by *subtracting* 8 | |
3657 | * from value in HD_MIN_ENERGY_CCK_DET_INDEX. | |
3658 | * | |
3659 | * For all cases (too few, too many, good range), make sure that the CCK | |
3660 | * detection threshold (energy) is below the energy level for robust | |
3661 | * detection over the past 10 beacon periods, the "Max cck energy". | |
3662 | * Lower values mean higher energy; this means making sure that the value | |
3663 | * in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy". | |

3752 | * | |
3753 | * DISCONNECTED ANTENNA: | |
3754 | * | |

3785 | * (accum_noise[i] - accum_noise[reference]) / 30 | |
3786 | * | |
