[[Effective Isotropic Radiated Power]] ([[EIRP]]) biasanya kita gunakan. Kita biasanya membatasi [[EIRP]] sekitar 36dBm. Di Indonesia, kita mengadopsi batasan [[EIRP]] yang berbeda bagi sambungan [[Point-to-Point]] ([[P2P]]) dan sambungan [[Point-to-Multi-Point]] ([[P2MP]]), menjadi 36 dBm dan 30 dBm. | [[Effective Isotropic Radiated Power]] ([[EIRP]]) biasanya kita gunakan.

Pemerintah maupun konsensus komunitas kemungkinan besar akan menentukan batasan-batasan maksimum dari daya yang boleh di pancarkan dari antenna. Daya yang dipancarkan dari antenna dapat di ukur dengan dua (2) cara yaitu:
Effective Isotropic Radiated Power (EIRP) dalam dBm = daya di input antenna [dBm] + penguatan antenna [dBi]
Effective Radiated Power (ERP) dalam dBm = daya di input antenna [dBm] + penguatan antenna [dBd]
Effective Isotropic Radiated Power (EIRP) biasanya kita gunakan. Kita biasanya membatasi EIRP sekitar 36dBm. Di Indonesia, kita mengadopsi batasan EIRP yang berbeda bagi sambungan Point-to-Point (P2P) dan sambungan Point-to-Multi-Point (P2MP), menjadi 36 dBm dan 30 dBm.
Contoh perhitungan daya Effective Isotropic Radiated Power (EIRP)
| TX Power | Power Gain / Loss | Power | Antenna gain | EIRP | Legal? | (Yes / No) |
|---|---|---|---|---|---|---|
| 1 Watt | (+30 dBm) | -1 dB loss via 1 m coax | + 29 dBm | +6 dBi | +35 dBm | Yes |
| 100 mW | (+20 dBm) | +14 dB Amplifier | +34 dBm | +8 dBi | +42 dBm | No |
| 25 mW | (+14 dBm) | +14 dB Amplifier | +28 dBm | +8 dBi | +36 dBm | Yes |
