152 * Quality statistics about the currently active link.
156 * Statistics required for Link tuning.
157 * For the average RSSI value we use the "Walking average" approach.
158 * When adding RSSI to the average value the following calculation
161 * avg_rssi = ((avg_rssi * 7) + rssi) / 8;
163 * The advantage of this approach is that we only need 1 variable
164 * to store the average in (No need for a count and a total).
165 * But more importantly, normal average values will over time
166 * move less and less towards newly added values this results
167 * that with link tuning, the device can have a very good RSSI
168 * for a few minutes but when the device is moved away from the AP
169 * the average will not decrease fast enough to compensate.
170 * The walking average compensates this and will move towards
171 * the new values correctly allowing a effective link tuning.
177 * Statistics required for Signal quality calculation.
178 * For calculating the Signal quality we have to determine
179 * the total number of success and failed RX and TX frames.
180 * After that we also use the average RSSI value to help
181 * determining the signal quality.
182 * For the calculation we will use the following algorithm:
184 * rssi_percentage = (avg_rssi * 100) / rssi_offset
185 * rx_percentage = (rx_success * 100) / rx_total
186 * tx_percentage = (tx_success * 100) / tx_total
187 * avg_signal = ((WEIGHT_RSSI * avg_rssi) +
188 * (WEIGHT_TX * tx_percentage) +
189 * (WEIGHT_RX * rx_percentage)) / 100
