What EAF | Siga Antenado does

EAF (Entidade Administradora da Faixa 3.5 GHz), legally Associação Administradora da Faixa de 3,5 GHz, is a Brazilian non-profit entity created in 2021 by Anatel determination to execute the digital inclusion and spectrum management obligations from Brazil's 5G auction. Founded and funded by Claro, TIM, and Vivo — the winning bidders of the national 3.5 GHz spectrum lots — EAF operates under supervision of the Ministério das Comunicações and Anatel's GAISPI oversight group. The organization has approximately 100 employees and executes five major public programs: Brasil Antenado (free digital parabolic antennas for low-income CadÚnico families across 254,000+ households in 16 states), Norte Conectado (the world's largest subfluvial fiber optic network at 13,200 km across Amazon rivers, with R$ 1.3 billion in committed investment), Rede Privativa de Comunicação da Administração Pública Federal (a sovereign encrypted network connecting 6,500 federal government endpoints across 27 capitals), Siga Antenado (the concluded C-Band to Ku-Band transition program serving 5+ million families), and the completed FSS Mitigation and Clearance program (1,482 stations migrated, 18,741 mitigated across 5,570 municipalities).

EAF's core technology portfolio spans satellite TV distribution (Banda Ku digital parabolic antennas) and subfluvial fiber optic infrastructure, supported by proprietary engineering systems including the LCE (Line Cable Engine) capable of laying cables at depths up to 18 meters, the 80m modular Balsa-Plataforma de Lançamento, and an internally developed real-time GPS-based cable deployment monitoring system. Its fiber optic cables carry 48 fiber pairs with up to 96 Tbps transmission capacity. The technical scope is reinforced by CMAD (Centros Móveis de Alta Disponibilidade) — solar- and lithium-powered mobile connectivity hubs designed for the Amazon climate. Distribution leverages a 30,000+ partner installer network, multi-channel community outreach (Cinema Itinerante, Caravana Brasil Antenado, WhatsApp scheduling), and the Operador Neutro model where local ISPs rent capacity on the Norte Conectado backbone for last-mile delivery.

EAF's business model is non-commercial: it is funded by Claro, TIM, and Vivo as part of their 5G auction obligations, with all services delivered free of charge to beneficiaries — no subscription fees, no internet requirements for TV programs. The organization's customers are not revenue-paying clients but rather beneficiaries of public policy: low-income families (CadÚnico), Amazon region communities (where 79% of residents lack home internet), and federal government bodies requiring sovereign communications. Revenue disclosure is not applicable in the conventional sense; operations are funded through statutory obligation transfers from the three telecom operators.

Core offering

EAF is a Brazilian non-profit entity created by Anatel to execute the 5G auction obligations of operators Claro, TIM, and Vivo. It runs five public digital-inclusion programs: Brasil Antenado (free satellite TV antennas for low-income families), Norte Conectado (subfluvial fiber optic network across the Amazon), Rede Privativa (secure federal government communications), Siga Antenado (C-Band to Ku-Band TV transition), and Mitigação FSS (satellite interference clearance enabling 5G deployment).

Product overview

EAF (Entidade Administradora da Faixa 3.5 GHz) operates as a non-profit entity created by Anatel to execute 5G deployment obligations in Brazil. The organization manages a portfolio of digital inclusion programs: Brasil Antenado provides free digital TV antennas to low-income families; Norte Conectado deploys fiber optic infrastructure through Amazon river beds; Rede Privativa builds secure government telecommunications networks; and Siga Antenado managed the C-Band to Ku-Band TV signal transition. These interconnected programs work together to expand connectivity, bridge digital divides, and deliver public policy objectives across Brazil.
