Smart Communications
2G (GSM)
Smart has 2 GSM blocks in use. Smart uses 900MHz (E-GSM) and 1800 MHz (DCS) spectrum for 2G.
Cell ID Layout
The first value is the 900MHz (E-GSM) block. If Cell ID starts with 7 or 8:
| Sector ID | Frequency Band | Direction |
| 1 | 900MHz (E-GSM) | North |
| 2 | 900MHz (E-GSM) | East southeast |
| 3 | 900MHz (E-GSM) | West southwest |
The second value is the 1800 MHz (DCS) block. So 1 and 4, 2 and 5, and 3 and 6 face the same direction. If Cell ID starts with 7 or 8:
| Sector ID | Frequency Band | Direction |
| 1 | 1800 MHz (DCS) | North |
| 2 | 1800 MHz (DCS) | East southeast |
| 3 | 1800 MHz (DCS) | West southwest |
If Cell ID isn't starting with 7 or 8 sectors are named randomly mostly with a number from 0-9.
3G (UMTS)
Smart has 2 UMTS blocks in use. Smart uses 900MHz (E-GSM) and 2100 MHz (IMT) spectrum for 3G. Smart 3G network is scheduled to sunset on 2023.
Cell ID Layout
| Sector ID | Frequency Band | Direction |
| 1,4 | 2100 MHz (IMT) | North |
| 2,5 | 2100 MHz (IMT) | East southeast |
| 3,6 | 2100 MHz (IMT) | West southwest |
The second value is the 900MHz (E-GSM) block. So 1 and 4, 2 and 5, and 3 and 6 face the same direction.
| Sector ID | Frequency Band | Direction |
| 7 | 900MHz (E-GSM) | North |
| 8 | 900MHz (E-GSM) | East southeast |
| 9 | 900MHz (E-GSM) | West southwest |
4G (LTE)
Smart has 6 LTE blocks in use. Smart has deployed LTE on 700 MHz (APT B28) 15 MHz, 850 MHz (CLR B5) 10 MHz, 1800 MHz (DCS B3) 15 MHz, 2100 MHz (IMT B1) 15/20 MHz, 2300 MHz (WCS B40) 20 MHz and 2500 MHz (BRS/EBS B41) 15 MHz/20 MHz. DCS is Smart's primary LTE band. It was used exclusively during Smart's initial LTE deployment in 2012. Smart also owns 20 MHz of 3400MHz (CBRS B42) but decommissioned in the end of July 2022.
