MIT economist and Eridan engineer argue wireless reform is key to AI growth

A new MIT CSAIL and Eridan white paper says the U.S. can unlock more AI-driven economic growth only if wireless networks get denser and regulators update outdated rules. The authors argue the technical limits to small-cell deployment have eased, leaving policy as the main bottleneck.

Why it matters: - The paper says wireless infrastructure is a missing piece of AI infrastructure in the United States. - The authors argue that denser, lower-power small-cell networks are needed to support AI growth and U.S. global competitiveness. - The paper frames wireless as the "central nervous system" for the AI economy.

What happened: - Eridan Communications announced the publication of a white paper co-authored by William Lehr of MIT CSAIL and Douglas Kirkpatrick, Eridan's co-founder and chief technology officer. - The paper, Wireless is the Connective Tissue of Our AI Future: Success Requires a Paradigm Shift in Both Wireless Technology and Regulation, is publicly available through SSRN at Eridan’s website and at the SSRN listing. - The announcement was made July 9, 2026, from Sunnyvale, California.

The details: - The paper says two barriers have slowed the shift to denser wireless networks: technology and regulation. - The technology barrier is described as the inefficiency of legacy radio designs. - The authors say that barrier has been addressed through commercial availability of a new class of radio hardware. - The regulatory barrier remains. - The paper points to antenna siting rules, outdated interference thresholds and spectrum licensing structures that favor incumbent operators. - Lehr is a Research Affiliate at MIT CSAIL and has focused for decades on telecommunications economics, Internet infrastructure and spectrum policy. - Lehr has informed FCC and other policy debates, testified before Congress and worked on spectrum management and broadband policy. - Kirkpatrick is credited as the inventor of the switch-mode direct polar GaN radio architecture discussed in the paper. - The paper says that architecture enables full 5G performance at power levels comparable to a home WiFi router. - The authors say that result became practical only after advances in GaN semiconductor manufacturing, switching circuit design and polar modulation converged. - Eridan says its 5G cellular radios deliver Ultra-Clean Signal performance with significantly less power. - Eridan is based in Sunnyvale, California, and says its radio technology supports carrier-grade performance at a fraction of the energy footprint.

Between the lines: - The paper shifts the debate from whether dense small-cell networks are technically possible to whether policy is keeping deployment from scaling. - That framing puts regulators, not engineers, at the center of the next phase of wireless buildout. - If accepted by policymakers, the argument could support changes to siting, interference and licensing rules.

What's next: - The paper is now available publicly for researchers, policymakers and industry readers. - The next test is whether regulators act on the paper's call for a different framework for wireless deployment. - Eridan is continuing to position its radio hardware around energy-efficient 5G infrastructure for AI-related demand.
