Yang Xuezhi, a former Huawei scientist and telecommunications expert known for inventing the 4G Soft Frequency Reuse (SFR) technology, recently sparked controversy after publishing an article criticizing Huawei’s newly announced “Tao (τ) Law.”
The debate began after Huawei Semiconductor Business President He Tingbo introduced the “Tao Law” on May 25, 2026. Huawei describes it as a chip-design concept that improves semiconductor performance through circuit architecture optimization, signal-timing improvements, and system-level efficiency gains, rather than relying primarily on transistor miniaturization as envisioned by Moore’s Law.
Yang argued that the technology represents a valuable engineering optimization rather than a fundamental scientific breakthrough. He contended that the concepts underlying the “Tao Law,” such as reducing signal delays and optimizing circuit timing, are well-established industry practices and do not justify being labeled a new “law.” He accused Huawei of repackaging existing technologies, exaggerating their significance through marketing, and engaging in what he described as a long-standing pattern of overstating research achievements.
The article was subsequently removed from Chinese online platforms. In response, a number of Chinese commentators and technology writers published rebuttals defending Huawei’s technological contributions. Others attacked Yang personally, labeling him a “loser” and arguing that his criticism stemmed from resentment over his departure from Huawei in 2012 rather than from objective academic concerns.
