Could a 5G Radio Inside the GPU Package Meet the Chip Security Act? Texas A&M's 5G CATS Paper of 10 November 2026 and the Location Verification Rule in S.1705

What the Chip Security Act would require of exported AI chips

Senator Tom Cotton's Chip Security Act, S.1705, introduced on 8 May 2025, would direct the Secretary of Commerce, within 180 days of enactment, to require that advanced AI chips and the computers built around them carry security mechanisms that implement location verification before they are exported. The bill sets no technical method. It asks for techniques that are "feasible and appropriate" on the date the law is enacted, which makes the state of engineering at that moment part of the legal standard.

What the 5G CATS paper adds on 10 November 2026

A five-author team at Texas A&M University posted 5G CATS on arXiv on 10 November 2026. The design puts a 5G radio, a cryptographic engine and a hardware interlock on the GPU package itself and times an authenticated challenge against nearby low-latency base stations. In simulations of an unloaded cell, a checking station rejected every round of a fiber relay from 300 kilometers, against 2,000 kilometers for ordinary 5G. The authors state that the carrier cross-check is unsimulated and that capacity at large data centers remains to be evaluated.

Why the House remote access bill still matters

A chip that proves where it sits says nothing about who reaches it through a cloud account. The Remote Access Security Act, H.R. 2683, which passed the House and was referred to the Senate Banking Committee on 13 January 2026, addresses that second question. This post reads both bills against the paper and asks which technique a regulator could call feasible today.
