| This file defines the expected throughput values that should be used with the network_WiFi_Perf.* |
| tests. |
| |
| The expected throughput values depend on the following parameters: |
| 1- The test type: |
| a) TCP_BIDIRECTIONAL |
| b) TCP_RX |
| c) TCP_TX |
| a) UDP_BIDIRECTIONAL |
| b) UDP_RX |
| c) UDP_TX |
| Note: The thoughput is viewed from the DUT perspective: |
| streaming to DUT = RX |
| streaming from DUT = TX |
| simultaneous TX + RX = BIDIERECTIONAL |
| 2- The Connection mode: |
| a) 80211n |
| b) 80211ac |
| 3- The channel width: |
| a) 20 MHz |
| b) 40 MHz |
| c) 80 MHz |
