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

213 * (WEIGHT_TX * tx_percentage) +
214 * (WEIGHT_RX * rx_percentage)) / 100
