    9898== Throughput vs. Payload Length ==
    99 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.

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