## Introduction AI data centers are becoming increasingly important for AI applications. However, the growing demand has led to limitations in copper availability and optical interconnections. To overcome this problem, researchers have developed a new radio-based connection called 'active radio cable'. ## How it works This system uses millimeter-wave and terahertz frequencies to transmit data at high speeds. Specifically, it offers a transmission capacity of 1.6 TB/s using only half the volume required for traditional copper cables. ## Advantages The primary advantage of this system is that it does not require the use of traditional materials such as copper or optical fibers. Additionally, it offers high-speed data transmission without introducing interference and distortion that can compromise data quality. ## Applications This technology has already found applications in various industries, including telecommunications, data centers, and automotive. Its scalability and flexibility make it an excellent solution for applications requiring high-speed transmission and low energy consumption. ## Conclusion In conclusion, radio-based connection technology offers a new possibility to overcome copper limitations and optical interconnections. Its scalability, flexibility, and high-speed transmission capabilities make it an excellent solution for applications requiring high-speed data transmission and low energy consumption.
