Summary
- New transceiver achieves 15 GB/s, far exceeding current consumer wireless.
- Analog signal processing drastically cuts energy use while boosting speeds.
- Three sub-transmitters replace DACs, consuming only 230 milliwatts.
Researchers at the University of California, Irvine, have unveiled a novel wireless transceiver capable of achieving data transfer rates of 15 GB/s, significantly exceeding the capabilities of current consumer wireless systems. This breakthrough operates in the 140GHz range, pushing speeds approximately 300% beyond Wi-Fi 7 and an astounding 2300% past 5G mmWave.
A key innovation lies in the transceiver's use of analog signal processing. This approach dramatically lowers energy consumption by replacing conventional, power-intensive digital-to-analog converters (DACs) with three synchronized sub-transmitters. These consume a mere 230 milliwatts, a fraction of what traditional DACs would require for comparable throughput, thus avoiding a significant bottleneck in existing designs.
Fabricated on a single integrated silicon chip using a 22nm process, the transceiver avoids the complexities of leading-edge manufacturing. This makes large-scale production more feasible and potentially lowers costs. The demonstrated speeds rival fiber optic links, suggesting future applications in replacing extensive cabling within data centers, offering enhanced flexibility and reduced installation expenses.
