=== Peak Throughput ===

This test measures the peak throughput between two PCs connected via the OFDM Reference Design's CSMA application. The PCs use the OFDM/CSMA link as a wired-wireless bridge, emulating a point-to-point Ethernet link.

'''Methodology''': this test is conducted using two WARP Kits (SISO Kit v1), with radios connected via coax cables with 60dB series attenuation. The FPGA boards are each connected via Ethernet to a MacBook laptop. The setup is illustrated below.

We use [http://sourceforge.net/projects/iperf/ iperf] for throughput testing. One MacBook runs an iperf server, the other runs the iperf client, using one of the following calls:
{{{
#!sh
#For UDP tests:
iperf -c 10.0.0.1 -u -b 20M -l 1470 -t 30

#For TCP tests:
iperf -c 10.0.0.1 -l 1470 -t 30
}}}

'''Results:'''
Throughput in Mbps, as reported by iperf:
|| Full Rate || TCP || UDP ||
|| QPSK || 6.6 || 8.4 ||
|| 16-QAM || 9.7 || 13.1 ||
