Brazil – Public consultation No. 39 – Technical and operational requirements for the use of radio frequency bands associated with services of collective interest

The objective of this Public Consultation is to approve the Technical and Operational Requirements for the use of frequency bands associated with services of collective interest provided by terrestrial systems, as set out in the Annex to this Act. And to revoke:

I – Act No. 4.456, of June 11, 2018, which approves the power limits of the 39.50 – 40.00 GHz sub-band, for use by Multimedia Communication Service stations;

II – Act No. 2,934, of June 1, 2020, which approves the technical and operational requirements for use of the 2,300 MHz to 2,400 MHz band for use by stations in the Personal Mobile Service – SMP, Multimedia Communication Service – SCM, Fixed Switched Telephone Service – STFC and Private Limited Service – SLP;

III – Act No. 1.477, of March 5, 2021, which approves the technical and operational requirements for the conditions of use of the 3.300 MHz and 3.700 MHz sub-band, by stations in the Personal Mobile Service – SMP, Multimedia Communication Service – SCM, Fixed Switched Telephone Service – STFC and Private Limited Service – SLP;

IV – Act No. 3,543, of May 19, 2021, which approves the technical and operational requirements for the conditions of use of the 24.25 – 27.5 GHz sub-band by stations in the Personal Mobile Service – SMP, Multimedia Communication Service – SCM, Fixed Switched Telephone Service – STFC and Private Limited Service – SLP;

The public consultation also establishes changes to the following bands:

400 MHz BAND

– Defines the power limits to be followed;

– Defines additional operating conditions (specific frequency bands, applications, and coverage) – PtP and PmP

450 MHz BAND

– Defines the power limits to be followed;

– Defines additional operating conditions

700 MHz BAND

– Defines the power limits to be followed;

– Defines the limits of unwanted emissions to be followed;

– Defines additional operating conditions (band sharing between Radiocommunications and TV broadcasting).

800 MHz BAND

– Defines the power limits to be followed;

– Defines additional operating conditions.

900 MHz BAND

– Defines the power limits to be followed;

– Defines additional operating conditions.

1.710 MHz TO 1.880 MHz SUBBAND

– Defines the power limits to be followed;

– Defines additional operating conditions.

1.880 MHz TO 1.885 MHz AND 1.910 MHz TO 1.920 MHz SUBBANDS

– Defines the power limits to be followed;

– Defines additional operating conditions.

1.900 MHz AND 2.100 MHz BANDS

– Defines the power limits to be followed;

– Defines additional operating conditions.

2.300 MHz TO 2.390 MHz SUB-BAND

– Defines the power limits to be followed;

– Defines the limits of unwanted emissions to be followed.

2.500 MHz TO 2.690 MHz SUBBAND

– Defines the power limits to be followed;

– Defines the limits of unwanted emissions to be followed;

– Defines additional operating conditions.

2.570 MHz TO 2.618 MHz SUBBAND

– Defines the power limits to be followed;

– Defines additional operating conditions.

3.300 MHz TO 3.700 MHz SUBBAND

– Defines the power limits to be followed;

– Defines the limits of unwanted emissions to be followed;

24.25 GHz TO 27.5 GHz SUB-BAND

– Defines the power limits to be followed;

– Defines the limits of undesired emissions to be followed;

– Defines additional operating conditions (satellite interference must be avoided).

39.5 GHz TO 40 GHz SUB-BAND

– Defines the power limits to be followed;

– Defines the limits of unwanted emissions to be followed.
The final date for contributions for this is September 17th, 2023.
