Japan's high-speed rail operator JR Central will introduce upgraded bullet train suites this October, integrating innovative 5G and noise-reduction technology. The new premium suites will feature windows with embedded 5G antennas developed by AGC, which maintain a direct line-of-sight to base stations even at speeds up to 285 km/h, offering passengers more stable and faster onboard Wi-Fi. Traditional train Wi-Fi setups often struggle with signal interruptions due to the rapid movement of trains past network towers. Additionally, the cabins will include NTT's Personalized Sound Zone (PSZ) technology, which applies noise-cancelling principles similar to headphones, detecting ambient noise and generating an inverse waveform to cancel it, creating a quieter environment.

These upgrades aim to improve travel experi
