The fieldtest was conducted on 13 May 2016, near Paderborn, Germany. We used ath9k-based WiFi cards with a recent Linux kernel, supporting IEEE 802.11p OCB mode to send BPSK 1/2 and QPSK 1/2 frames with sizes of 200 byte, 500 byte, and 800 byte on channel 178 (5.89 GHz). The receiver was an Ettus Research N210 with an CBX daughterboard. Both sender and receiver used 6dBi dipol antennas and were equipped with NEO-7N GPS devices from u-blox.
