IEEE 802.11p RTT on real-time Linux kernel under GNU Radio TX jamming (24 Mbps bitrate)
A video recording demonstrates the testing of IEEE 802.11p Round-Trip Time (RTT) on a real-time Linux kernel. The GNU Radio TX jamming, operating at 5.89 GHz, illustrates the disruption of the RTT ping/pong communication at that frequency. By fixing the TX jamming with a coding different from 16QAM, the disturbance becomes more apparent.
802.11p frequency: 5.89 GHz (CCH)
Bandwidth = 10Mhz
TX power: 17 dBm (max)
Max TX jamming frequency: 100Hz
