198 * When adding RSSI to the average value the following calculation
201 * avg_rssi = ((avg_rssi * 7) + rssi) / 8;
203 * The advantage of this approach is that we only need 1 variable
204 * to store the average in (No need for a count and a total).
205 * But more importantly, normal average values will over time
206 * move less and less towards newly added values this results
207 * that with link tuning, the device can have a very good RSSI
208 * for a few minutes but when the device is moved away from the AP
209 * the average will not decrease fast enough to compensate.
210 * The walking average compensates this and will move towards
211 * the new values correctly allowing a effective link tuning.
217 * Statistics required for Signal quality calculation.
218 * For calculating the Signal quality we have to determine
219 * the total number of success and failed RX and TX frames.
220 * After that we also use the average RSSI value to help
221 * determining the signal quality.
222 * For the calculation we will use the following algorithm:
224 * rssi_percentage = (avg_rssi * 100) / rssi_offset
225 * rx_percentage = (rx_success * 100) / rx_total
226 * tx_percentage = (tx_success * 100) / tx_total

228 * (WEIGHT_TX * tx_percentage) +
229 * (WEIGHT_RX * rx_percentage)) / 100
