The use of atomic clocks in telecommunications supports the growing demands of modern communication systems, including 5G networks and high-speed internet services. They enable the precise coordination of base stations, allowing for seamless handovers and efficient spectrum utilization. In fiber optic networks, atomic clocks help maintain the timing of data pulses over long distances, reducing errors and ensuring reliable transmission. As communication networks continue to evolve, the precision and reliability offered by atomic clocks remain indispensable for meeting the synchronization requirements of next-generation technologies.
