On April 30, 2026, ANATEL published Act No. 5885, establishing comprehensive technical requirements and conformity assessment procedures for internal signal boosters used in the Personal Mobile Service (SMP) in Brazil. This Act revokes the previous Act No. 2271/2022 and introduces updated definitions, technical parameters, and mandatory procedures for the approval and operation of both wideband and selective signal boosters, whether fixed or mobile.

The regulation sets strict limits on transmission power, in-band and out-of-band gain, noise, intermodulation, and frequency stability. It also mandates advanced features such as automatic monitoring, anti-oscillation mechanisms, and automatic gain control to prevent harmful interference with SMP networks and other telecommunications services. All devices must include clear warnings regarding the need for prior authorization from SMP providers and the obligation to cease operation in case of interference.

Manufacturers are required to provide comprehensive user manuals, support information, and materials outlining consumer responsibilities and procedures in the event of interference. The conformity assessment process is based on internationally recognized FCC KDB procedures, adapted to the Brazilian regulatory context.

The Act is effective immediately upon publication, meaning all internal signal boosters for SMP to be marketed or installed in Brazil must comply with these new requirements. The regulation has significant implications for manufacturers, importers, certification bodies, operators, and end users, aiming to ensure service continuity, network integrity, and user safety.

This regulation is classified as High Impact.

Key reasons for high impact:

• Mandatory and immediate application to all internal signal boosters for SMP in Brazil.
• Revocation of previous requirements and introduction of new, detailed technical and procedural obligations.
• Direct effect on product design, testing, labeling, documentation, and approval processes.
• Broad impact on manufacturers, importers, certification bodies, operators, and end users.

Who is affected?

Manufacturers and importers of signal boosters, certification bodies, testing laboratories, SMP operators, distributors, installers, and end users.

Conclusion:

All stakeholders involved in the production, importation, certification, and use of internal signal boosters for SMP in Brazil must urgently review and adapt to the new requirements to ensure compliance and market access.
