Mexico's telecommunications regulator is preparing a spectrum auction reserved for private 5G industrial networks, according to trade publication Inside Towers, which reported the plan without publishing band, price or timeline details.

If executed, the auction would create a second track for industrial users to obtain 5G spectrum in Mexico, alongside the country's three national mobile carriers — Telcel (América Móvil), AT&T Mexico and Movistar (Telefónica).

What the report actually says

The Inside Towers item is a brief. It confirms an auction is planned and that the target use case is private 5G for industrial sites. It does not name the regulator, specify the spectrum band, set a reserve price, or give a date. Mexico's spectrum authority, the Instituto Federal de Telecomunicaciones (IFT), has not yet issued a public consultation on the proposal.

That thinness is itself the story. Mexican industrial users — and the systems integrators courting them — have been waiting since 2023 for clarity on private cellular licensing.

Why an industrial auction, in a market where commercial 5G is still small?

Commercial 5G in Mexico covers a fraction of the population. Brazil cleared its 3.5 GHz auction in 2022 and now reports 5G coverage above 25%; Chile began 5G deployment in 2021 and sits higher still. Mexico's slower commercial rollout has not stopped industrial demand. Automotive plants in the Bajío region, mining operations in Sonora, and logistics hubs around Monterrey have tested private LTE and early 5G kits for years — usually on carrier-leased capacity or unlicensed shared spectrum where available.

A dedicated auction would let those users license spectrum directly, set their own coverage and quality-of-service rules, and avoid dependence on a mobile operator's roadmap.

What questions remain unanswered?

Three decisions will determine whether the auction attracts bidders or stalls.

• Band. The 3.5 GHz C-band is the global workhorse for private 5G. Mexico's existing 5G plan centres on 3.45–3.6 GHz, with adjacent blocks already assigned to carriers. An industrial auction must fit inside, or beside, that plan without creating interference disputes.
• Geography. Nationwide licences attract different buyers than campus-by-campus lots. Germany has issued roughly 100 campus licences in 3.7–3.8 GHz since 2019, mostly one per site. Brazil's 2022 auction offered regional blocks that mixed private and public-network obligations.
• Coexistence. Private networks cannot be allowed to knock out a carrier's macro coverage, nor can they be unusable in their own right. The IFT will need to publish coordination rules before the auction moves.

Who is likely to bid?

Mexico lacks a deep pool of dedicated private-5G operators. The probable bidders are global integrators (Accenture, NTT Data, Kyndryl), equipment vendors with services arms (Ericsson, Nokia, Huawei) and the largest industrial groups with captive telecom needs. Names like Cemex, FEMSA and Bimbo have all explored private wireless, but rarely as spectrum buyers. A clear licence design will determine whether they bid directly or stick to carrier-leased models.

How much might the spectrum cost?

Germany's campus licences were effectively free. Brazil's regional 5G lots drew winning bids averaging in the low single-digit millions of US dollars. Mexico's IFT has historically leaned toward revenue-raising auctions, so reserve prices may sit higher — but the industrial use case constrains what bidders will pay for spectrum that does not serve consumer handsets.

Does the auction actually deliver private 5G?

The Mexican government has framed industrial digitalisation as part of its nearshoring agenda. A private 5G auction fits that narrative. It does not, on its own, deliver a private 5G network: someone still has to build, integrate and operate it, and the equipment ecosystem remains dominated by three foreign vendors. The auction is a necessary first step, not a deployment.

What comes next?

The IFT is expected to publish a consultation paper before formally launching the auction. That document will fix the band, the licence area, the duration and any deployment milestones. Until it lands, the auction is a directional signal — and Mexico's industrial users, having waited nearly two years for it, will be measuring the next announcement against that clock.
