176 * Quality statistics about the currently active link.
180 * Statistics required for Link tuning.
181 * For the average RSSI value we use the "Walking average" approach.
182 * When adding RSSI to the average value the following calculation
185 * avg_rssi = ((avg_rssi * 7) + rssi) / 8;
187 * The advantage of this approach is that we only need 1 variable
188 * to store the average in (No need for a count and a total).
189 * But more importantly, normal average values will over time
190 * move less and less towards newly added values this results
191 * that with link tuning, the device can have a very good RSSI
192 * for a few minutes but when the device is moved away from the AP
193 * the average will not decrease fast enough to compensate.
194 * The walking average compensates this and will move towards
195 * the new values correctly allowing a effective link tuning.
201 * Statistics required for Signal quality calculation.
202 * For calculating the Signal quality we have to determine
203 * the total number of success and failed RX and TX frames.
204 * After that we also use the average RSSI value to help
205 * determining the signal quality.
206 * For the calculation we will use the following algorithm:
208 * rssi_percentage = (avg_rssi * 100) / rssi_offset
209 * rx_percentage = (rx_success * 100) / rx_total
210 * tx_percentage = (tx_success * 100) / tx_total
211 * avg_signal = ((WEIGHT_RSSI * avg_rssi) +
212 * (WEIGHT_TX * tx_percentage) +
213 * (WEIGHT_RX * rx_percentage)) / 100
