Probing forthcoming rain cells using backscatter radar to anticipate link attenuation and adapt modulation seconds before packet loss occurs.
Rain drops attenuate 18 GHz and 24 GHz microwave signals severely. FinanceISAC channels double as weather radar, detecting approaching rain fronts 10 km away and calculating exact decibel attenuation profiles.
Seconds before rain fade strikes, the transmitter dynamically shifts from 4096-QAM down to QPSK while boosting RF power by 12 dB, sustaining the low-latency link without dropping a single trading frame.
