Frequency Bands
GSM
| Name | Interface | Description |
|---|---|---|
| 900 MHz (E-GSM) | GSM | Claro Brazil uses the GSM 900 MHz (E-GSM) frequency band. This band ranges from 880 MHz to 915 MHz for the uplink and from 925 MHz to 960 MHz for the downlink. The GSM 900 MHz (E-GSM) band is primarily used in various parts of the world, including Europe, Asia, Africa, the Middle East, and Australia. |
| 1800 MHz (DCS) | GSM | Claro Brazil uses the GSM 1800 MHz (DCS) frequency band. This band ranges from 1710 MHz to 1785 MHz for the uplink and from 1805 MHz to 1880 MHz for the downlink. The deployment of this band in Brazil began in the 1990s, with the initial GSM services launched in 1990. By the early 2000s, GSM 1800 had become widely used across the country. |
Supported GSM Protocols
| Name | Generation |
|---|---|
| GPRS | 2.5G |
| EDGE | 2.5G |
UMTS
| Name | Interface | Description |
|---|---|---|
| B1 (2100 MHz) | UMTS | Claro Brazil uses the UMTS B1 (2100 MHz) frequency band. It was deployed in November 2007. |
| B5 (850 MHz) | UMTS | Claro Brazil uses UMTS B5 (850 MHz). |
Supported UMTS Protocols
| Name | Generation |
|---|---|
| UMTS | 3G |
| HSDPA | 3.5G |
| HSPA+ | 3.5G (4G speed) |
LTE
| Name | Interface | Description |
|---|---|---|
| B7 (2600 MHz) | LTE | Claro Brazil uses the LTE B7 (2600 MHz) frequency band. The deployment of this frequency band is not specified. |
| B1 (2100 MHz) | LTE | Claro Brazil uses LTE band B1 (2100 MHz). This band is deployed for LTE services in Brazil. |
| B3 (1800 MHz +) | LTE | Claro Brazil uses LTE Band 3 (1800 MHz +) for its LTE deployments. This band is one of the most widely used frequency bands globally, supporting both FDD and TDD configurations. It is particularly popular in Europe, APAC, MEA, and selected countries in South America, facilitating international roaming for mobile broadband services. Claro Brazil has been utilizing this band since June 2014. |
| B5 (850 MHz) | LTE | Claro Brazil uses LTE Band 5 (850 MHz). The deployment of LTE Band 5 is limited globally due to the usage of the same spectrum by existing 2G GSM and 3G UMTS networks. |
| B28 (700 MHz APT) | LTE | Claro Brazil uses LTE Band 28 (700 MHz APT) for its 4G LTE network deployments. This band operates between 703 MHz and 803 MHz, supporting channel bandwidths of 5, 10, 15, and 20 MHz. The band is known for its excellent propagation characteristics, allowing signals to penetrate buildings and cover larger geographic areas with less infrastructure. It is widely used by public mobile operators for LTE network deployments and is also utilized for public safety communications in the United States. The deployment of the 700 MHz band in Rio de Janeiro significantly improved 4G availability by enhancing indoor penetration, although it resulted in lower download speeds compared to higher frequency bands. |
| B40 (TD 2300 MHz) | LTE | Claro Brazil uses LTE band 40 (TD 2300 MHz) for its LTE services. The deployment of this band is not specified in the provided information. |
Supported LTE Protocols
| Name | Generation |
|---|---|
| LTE | 4G |
5G NR
| Name | Interface | Description |
|---|---|---|
| N7 (2600 MHz) | 5G NR | Claro Brazil uses the 5G NR frequency band n7, which covers the range of 2500 to 2690 MHz. This band is commonly referred to as the 2.6 GHz 5G band. The n7 band is popular due to its relatively common availability, already widely used by 3G and 4G networks, and operators may "re-farm" existing 3G networks on these frequencies to repurpose them for 5G networks. Claro Brazil deployed the n7 band in June 2020, initially with a 20 MHz allocation. |
| N40 (2300 MHz) | 5G NR | Claro Brazil uses the 5G NR frequency band n40, which covers the 2300 to 2400 MHz range. This band was deployed as part of Claro's 5G network launch in July 2022. |
| N78 (3500 MHz) | 5G NR | Claro Brazil uses the 5G NR N78 (3500 MHz) frequency band. This band operates in the 3300 to 3800 MHz range and is designated for Time Division Duplexing (TDD). It is widely used for 5G deployments due to its relatively common availability and potential for high capacity throughput. The band supports channel bandwidths ranging from 10 MHz to 100 MHz and is particularly popular for its ability to support large channel widths, making it suitable for delivering high-capacity 5G services. Advanced technologies like massive MIMO, beam-forming, and beam-tracking help mitigate the limited range and building penetration issues associated with higher frequencies. |
