However, the terahertz frequencies that come with 6G cause environmental interference with the signals. This causes it to be extremely sensitive to factors. Current systems, signal transmission instantaneous phase shifts in their paths and delays caused by temperature changes It is unable to compensate in real time. This is especially true for multiple input-multiple output systems. In MIMO (Minimum Viable Product) systems and high-frequency carriers, it causes phase mismatch, resulting in signal 20. This reduces the quality. Also, in enclosed areas where GNSS signals are blocked, or Time discrepancies are increasing in high-density city centers, and network coordination is deteriorating. It is deteriorating. Because current techniques perform calculations based on fixed delay values. It is unable to adapt to dynamic channel conditions.
