Panel 3 – Spectrum Harmonization & Regulatory
Issues
Spectrum Committee
Create a consistent vision for the use of radiofrequency spectrum (Spectrum Committee Report) for mobile services and 5G in the Brazilian market in order to support (and align with) future contributions to domestic (Anatel CBC), regional (Citel) and international(ITU.R TG5 / 1 and WRC) boards, through the recommendations made and taking as a background: (1) the technological requirements of the current standard; (2) spectrum requirements in the different bands (<1 GHz, 1-6 GHz,> 6GHz) associated with
the idiosyncrasies of the services, their demands and technical characteristics (eg propagation, interference, etc.); (3) the harmonization of use by observing spectrum usage trends in the global and
regional environment, observing the current regulatory framework, coordination and coexistence between services, cleaning opportunities; (4) the optimization of its use through technologies of sharing,
spectral efficiency and reuse.

Requirements
Bands and Requirements5G will represent the convergence of networks with different service requirements, which are better
supported using specific spectrum range. ITU-R M.2290 Report has updated the spectrum forecast for the year 2020, which results in a needed
between 1340 and 1960 MHz (in Brazil 1129 MHz to 1676 MHz), depending on the market environment.

Bands below 1 GHzToday there are no new bands below 1GHz for the 5G. Other UHF sub-bands were identified in Regions
2 and 3, but not globally harmonized (Region 1). Thus, they are being considered (470-698 MHz) for discussion in WRC23.

Although the 450 MHz band is identified for IMT since WRC07, it was the first proposal made to 3GPP on 2012 WI R4-124497 on 3GPP RAN # 64.
There exists a lack bandwidth with 5+5 MHz, insufficient to promote a fair completion with 2 or more players.
There is no formal discussion about second wave of digital dividend in Brazil.
The range between 470-698 MHz was identified by regions 2 and 3, but not globally harmonized (Region 1). Considered for discussion in WRC23.
Currently it has initial usage after TVA switchoff in LTE networks.
It has high potential for 5G in mid and ling term
Although it has already been identified in other regions, including part of the 700 MHz in Brazil, only after WRC12 has it become a global band for mobile use, with allocation and identification for IMT in Region 1.

Currently, based on Res 454/2006, there is a limitation to use 2.5+2.5 MHz per operator and in total there has been designated 10+10 MHz.
Potentially, it can double after cleanup and redistribution of existing services.
Inherited from trunking iDENsystem, it has a potential of 15+15 MHz to be used for Mobile Broadband.
Currently is used for 2G, 3G and 4G technologies by operators that have license to use.
In total is 25 MHz with high potential to be refarmed to5G.
Midbands between 1 GHz and 3 GHzThese ranges of spectrum are fully used to previous mobile network systems: 2G, 3G and 4G. There
are a few opportunities such as L Band and 2300 MHz.

Band 7 / Band 38/ n7/n38Res 544/2010
--------
This band has seen increasing interest from regulators following its identification for IMT in 2015. In the European Union, 1452-1492 MHz was opened for downlink use in 2015. The common sense is to use SDL for the full L-band i.e., 1427-1518 MHz
These bands are currently used for 2G and 3G, and they are being refarmed to 4G. They must be candidate to future 5G deployment and complement the existing assigned bands.
Band S is currently used in several initiative for ATG (Air To Ground). For instance Band 65was recently created to enable ATG systems in Region 1.
Band 23, indicated below, is designated in the US for ATC (Ancillary Terrestrial Component) services complementary to the MSS.
This band has currently used as complementary Midbandin recent auctions, such as Ofcom
However 2300 MHz has expressive 4G penetration due China operators and as shared spectrum in EU using LSA.
In Brazil, it will complement 3500 MHz band in next year auction.
It has been used as preferable 4G (LTE) band around the world and specially Region 1 and in Brazil.
It has huge amount of traffic and it will be a candidate for 5G spectrum refarming;
Midbands between 3 GHz and 6 GHz
C Band (3500 MHz) is being naturally harmonized around world as preferable Midband to 5G. Today there exists more than 35 trials and deployments in course accordingly to GSA.

This range has beenIdentified in the 3 Regions, but very limited in only a few countries of the regions;
Japan and China are planning to used as band to 5G.
Unlicensed spectrum plentiful below 6 GHz -around 800 MHz;
Unlicensed spectrum is available and harmonized globally;
<6 GHz is preferable due to Path Loss;
The 5 GHz is free when compared to 2.4 GHz, dirty with most Wi-Fi and Bluetooth deployments;
