# India base-station limit, 400–2000 MHz

> f/2000 W/m² (f in MHz) — 0.45 W/m² at 900 MHz and 0.9 W/m² at 1800 MHz, one tenth of the ICNIRP figure for the same band.

## Key values

- **Limit value:** 200,000–1,000,000 µW/m² — Regulatory value — legally enforceable — The range is the band edges: 0.2 W/m² at 400 MHz to 1 W/m² at 2000 MHz. DoT norms state 0.45 W/m² at 900 MHz, 0.9 W/m² at 1800 MHz and 1 W/m² at 2100 MHz and above. Equivalent electric field is 0.434 √f V/m (18.4 V/m at 1800 MHz). [india-tarang-norms, india-dgt-emf]

- [India DoT base-station EMF norms (1/10th of ICNIRP)](https://emfbase.com/standards/india-dot-emf-norms): India enforces base-station exposure limits set at one tenth of the ICNIRP 1998 power-density reference levels, effective 1 September 2012 and applied as a telecom licence condition.
- [Macro cell tower (LTE / 5G sector antenna)](https://emfbase.com/emitters/cell-tower): Sector antennas radiate on the order of 1000 W EIRP per sector on the main beam, which is aimed above and away from the tower base — ground-level exposure directly beneath a tower is usually lower than at a few hundred metres away.
