Communication Systems

Here is how this works in practice. Mexican production communications run on a backbone of Motorola fleet radios programmed through Motorola Options Mexico's Carlos Slim-era partner network. This pairs with Lectrosonics IFB, Wisycom MTP and Sennheiser Digital 6000 wireless for talent feeds. We set up frequency clearances with the Instituto Federal de Telecomunicaciones (IFT) before principal photography begins, securing temporary range licenses that cover wireless mics, comms, and any wireless video hops on a single permit document.

On the ground, For productions basing at Estudios Churubusco, Lemon Studios, Argos Comunicación, or Televisa San Ángel, we layer Clear-Com FreeSpeak II beltpacks onto existing studio intercom infrastructure so director, AD, and script departments stay set up across multiple stages. Telcel, Movistar Mexico, and AT&T The country provide the cellular and 5G backbone for production-office connectivity. With Telcel's 5G rollout covering CDMX, Guadalajara, Monterrey, and Cancún since 2022 — enough bandwidth for Frame.io remote producer feeds and same-day dailies upload from base camp.

Here is the short of it. Heritage location work introduces comms challenges that off-the-shelf radio packages do not solve. The thick stone walls of CDMX's centro histórico cathedrals, Yucatán Maya pyramid complexes under INAH oversight, and Durango Western-era haciendas all kill VHF/UHF range, so we deploy Motorola DLR/DTR digital repeater systems with strategic antenna placement set up against ATA-carnet-imported gear lists. For productions echoing the multi-unit coordination of Spectre's Day of the Dead opening across the Zócalo, Sicario's Sonora border crossings, or Narcos: Mexico's parallel CDMX-Guadalajara units, we build channelized communication plans that segregate first-unit, second-unit, stunts, and crowd control onto separate frequencies while keeping a shared command channel for ADs. Cross-border productions from LA rental houses bring their own preferred Lectrosonics R400a packs and Vortex bidirectional comms via Tijuana-San Diego same-day delivery; we handle the IFT paperwork so US-allocated frequencies clear Mexican range without on-set surprises during the take.
