The National Telecommunications Agency (ANATEL) of Brazil Approves the allocation of the 3.5 GHz radio frequency band for mobile services and announces the regulation on conditions of use of the 3.5 GHz band.
Resolution nº 711
The purpose of this Regulation is to establish the conditions of use of the radio frequency band from 3,300 MHz to 3,600 MHz, for fixed services digital radiocommunication systems, in point-to-multipoint applications, and mobile services, as defined in the Radiocommunications Regulation of the ITU.
The range of radio frequencies from 3,300 MHz to 3,600 MHz shall be used by systems employing time division duplex (TDD).
| Blocks of Radio Frequency Sub-bands | |||||
|---|---|---|---|---|---|
| Block | Sub-band (MHz) | Block | Sub-band (MHz) | Block | Sub-band (MHz) |
| 1 | 3300 to 3310 | 11 | 3400 to 3410 | 21 | 3500 to 3510 |
| 2 | 3310 to 3320 | 12 | 3410 to 3420 | 22 | 3510 to 3520 |
| 3 | 3320 to 3330 | 13 | 3420 to 3430 | 23 | 3520 to 3530 |
| 4 | 3330 to 3340 | 14 | 3430 to 3440 | 24 | 3530 to 3540 |
| 5 | 3340 to 3350 | 15 | 3440 to 3450 | 25 | 3540 to 3550 |
| 6 | 3350 to 3360 | 16 | 3450 to 3460 | 26 | 3550 to 3560 |
| 7 | 3360 to 3370 | 17 | 3460 to 3470 | 27 | 3560 to 3570 |
| 8 | 3370 to 3380 | 18 | 3470 to 3480 | 28 | 3570 to 3580 |
| 9 | 3380 to 3390 | 19 | 3480 to 3490 | 29 | 3580 to 3590 |
| 10 | 3390 to 3400 | 20 | 3490 to 3500 | 30 | 3590 to 3600 |
The effective isotropically radiated powers (EIRP) of a base station and a terminal shall be the minimum required to perform the service with good quality and adequate reliability.
ANATEL will only allocate the radio frequencies to a telecommunications services provider if that provider presents a documentation proving their coordination with others that operate in that band.
Systems operating in the radiofrequency band of 3,300 MHz to 3,600 MHz, regularly authorized, and whose operation is in disagreement with the established in this Regulation, may continue in operation on a secondary basis and without extension.
