The future is analog.
Researchers from the University of California, Irvine have developed a transceiver that works in the 140 GHz range and can transmit data at up to 120 Gbps, that's about 15 gigabytes per second. By comparison, the fastest commercially available wireless technologies are theoretically limited to 30 Gbps (Wi-Fi 7) and 5 Gbps (5G mmWave). According to UC Irvine News, these new speeds could match most fiber optic cables used in data centers and other commercial applications, usually around at 100 Gbps. The team published their findings in two papers - the bits-to-antenna" transmitter and the antenna-to-bits" receiver - on the IEEE Journal of Solid-State Circuits.
The Federal Communications Commission and 6G standards bodies are looking at the 100-gigahertz spectrum as the new frontier," lead author Zisong Wang told the university publication. But as such speeds, conventional transmitters that create signals using digital-to-analog converters are incredibly complex and power-hungry, and face what we call a DAC bottleneck." The team replaced the DAC with three in-sync sub-transmitters, which only required 230 milliwatts to operate.
