Chinese tech giant Huawei has expanded its 'Logic Folding' technology, initially developed for smartphone application processors, to communication equipment chips in response to U.S. semiconductor sanctions.
According to a report by the South China Morning Post on October 29, Huawei has introduced communication equipment that applies the 'Tau Scaling Law' to next-generation wireless base stations. The latest baseband product series, UBBPi, reportedly increases average network efficiency by 1.3 times and reduces energy consumption by 40%. This marks the first time Huawei has applied the Tau Scaling Law to base stations.
The Tau Scaling Law shifts focus from reducing the physical size of transistors to minimizing the time signals travel within circuits. The core technology, Logic Folding, arranges circuits in a three-dimensional layout to shorten signal paths. This allows for improvements in computational speed and power efficiency without the need for extreme ultraviolet (EUV) lithography.
Huawei also applied Logic Folding to the Kirin 9050 Pro chip in its recently unveiled Mate XT2 foldable smartphone, claiming a 42% overall performance improvement and enhanced power efficiency compared to its predecessor. The company has set a goal to increase the transistor density of high-performance chips based on the Tau Scaling Law to levels equivalent to a 1.4nm process by 2031.
Communication chips differ from smartphone application processors or artificial intelligence accelerators. Baseband chips in base stations handle wireless signal processing and control data transmission for multiple devices. Communication semiconductors can be produced using mature processes, where circuit design and system optimization are crucial for product competitiveness.
Meanwhile, Huawei is accelerating its acquisition of next-generation communication technology. Alongside the UBBPi series, the company has introduced the VitaAAU, which it claims is the world's first commercial Upper 6 GHz equipment utilizing frequencies in the upper 6 GHz band. This equipment is currently being commercialized in the United Arab Emirates and supports download speeds exceeding 10 Gbps, according to Huawei.
