Summary of Resolution No. 766

Resolution No. 766, issued by the Directorate of the National Telecommunications Agency (ANATEL) on November 7th, modifies assignments for radio frequency subbands in the 4.9 GHz band and introduces Articles 35-A to 35-D to the Regulation on Conditions of Use of Radio Frequencies.

Key Provisions

This resolution includes six primary articles:

• Article 1 modifies the allocation of the frequency band from 4,830 MHz to 4,950 MHz for the Personal Mobile Service (SMP), Multimedia Communication Service (SCM), Switched Fixed Telephone Service (STFC), and Limited Private Service (SLP), on a primary non-exclusive basis.
• Article 2 revokes the assignment of the frequency band from 4,910 MHz to 4,950 MHz for the Limited Private Service (SLP) in Public Security and Civil Defense applications.
• Article 3 maintains the assignment of the frequency band from 4,950 MHz to 4,990 MHz for the Limited Private Service (SLP) in Public Security and Civil Defense applications, on a primary non-exclusive basis.
• Article 4 updates the Table of the Allocation, Destination, and Distribution Plan of Frequency Bands in Brazil.
• Article 5 states that the Regulation on Conditions of Use of Radio Frequency Bands will take effect with the following modifications:

Specific Articles

• Article 35-A specifies that the 4,830 MHz to 4,950 MHz frequency subband can be used for assigned terrestrial services of collective interest according to blocks listed in Table XI-A. Systems must support the Time Division Duplexing (TDD) method, remain synchronized to the same clock reference, and utilize compatible TDD frames to prevent interference. Occupation of frequency subbands should start from the center of a block moving outward.
• Article 35-B indicates that until September 7th, 2028, no licenses or frequency assignments will be granted to stations associated with terrestrial services in this frequency band unless restrictions are exempted, ensuring no harmful interference to other services.
• Article 35-C allows systems operating under previous authorizations to continue as per their original conditions, but new licenses or frequency assignments are restricted until September 6th, 2028.
• Article 35-D establishes that ANATEL will assign frequencies only after the service provider presents coordination documentation with other providers, ensuring parameters allow for coexistence and synchronization among systems in adjacent blocks.

This resolution will take effect on December 1st, 2023.
