== Throughput vs. SNR ==
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 [../wlan_exp the experiments framework]. The nodes' RF interfaces are connected via a coax cable and a variable attenuator. The attenuation is swept from 55dB to 83dB in 0.5dB steps.

== Throughput vs. Payload Length ==
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.

The plot below clearly illustrates increasing throughput with higher PHY rates and the decreasing impact of MAC overhead with increasing payload lengths.
