| 21 | | == Throughput vs. Payload Length == |
| 22 | | This test measures the achieved throughput of each PHY rate between two WARP v3 nodes running the 802.11 Reference Design. One node acts as AP, the other as a STA. Traffic is generated locally via the LTG framework; measurements are extracted from the nodes via WARPnet. The nodes' RF interfaces are connected via a coax cable and 50dB attenuation. |
| 23 | | |
| 24 | | The plot below clearly illustrates increasing throughput with higher PHY rates and the decreasing impact of MAC overhead with increasing payload lengths. |
