Vacant: Vacant, didn't receive proposals in the last auction for SMP leftovers.
Use of Bands A and B (850 MHz) for 3G
Mobile operators with frequencies in the 800 MHz band (Bands A and B) can use these frequencies to deploy UMTS 3G (WCDMA/HSDPA) systems. This band is being used by carriers in the United States such as AT&T to deploy their WCDMA/HSDPA network.
Claro and Tim have leftovers in 850 MHz spectrum as their customers have migrated to GSM and are using the 900 and 1800 MHz extension bands (more details). Vivo, Telemig and Claro deployed their 3G networks at 850 MHz.
Operators in Bands A and B (850 MHz) in Brazil
| SMC Area | Band A | Band B |
|---|---|---|
| 1 and 2 (São Paulo) | Vivo | Claro |
| 3 (Rio de Janeiro, Espírito Santo) | Vivo | Claro |
| 4 (Minas Gerais) | Telemig | TIM |
| 5 (Paraná, Santa Catarina) | TIM | Vivo |
| 6 (Rio Grande do Sul) | Vivo | Claro |
| 7 (Middle West) | ||
| 8 (Amazônia) | Claro | Vivo |
| 9 (Bahia, Sergipe) | Vivo | TIM |
| 10 (Northeast) | TIM | Claro |
Telemig and Claro could have been put in operation earlier |
Claro and Telemig had to wait for Anatel's authorization to enter into operation. Anatel claimed that it would first be necessary to repeal Res. 227 of June 2000 which allocates frequency bands for the implementation of IMT-2000 (3G). Note that this resolution didn't prevent the activation of EVDO from Vivo which is also IMT-2000.
Anatel has placed in public consultation a proposal to revoke resolution 227, removing doubts about the possibility of using the 850 MHz band for 3G. In Apr/08 the resolution was revoked.
Anatel announced on 10/31/07 that 3G technologies may be used in all bands for Personal Mobile Service (SMP). |
