The new waveform of the wireless ad-hoc network based on the SDR system currently supports line-of-sight communication up to 1000 kilometers, with waveform design supporting up to 2000 kilometers. The high-power devices have increased to 40W, 80W, 100W, and 300W. The operating frequency bands support U, L, and C bands.
Note:
One-way delay = ping packet delay / 2, where the ping packet delay is the average delay of 20 ping packets, representing the round-trip delay; The above results are based on tests conducted under indoor conditions without interference, with a high signal-to-noise ratio. These results only indicate that the waveform frame structure design can support distances of 500km to 2000km, and the test results are for reference only. The test results represent peak rates under corresponding distance conditions, while in actual long-distance conditions, the transmission power is limited, and the signal-to-noise ratio is low, resulting in transmission rates much lower than the peak rates. To improve transmission rates, it is necessary to increase transmission power and antenna gain.
