Power opgelegd door ITU Region 1= 15 Watts EIRP (equivalent isotropically radiated power (EIRP)where and (output power of transmitter) are in dBm, cable losses () is in dB, and antenna gain () is expressed in dBi, relative to a (theoretical) isotropic reference antenna.
EIRP= PT-LC+Ga
Omzetten van Watt naar dbm: 15 Watt eirp = +42dbm
Dipool toz isotroop is +2.15 db
Kabel verliezen : 1 db (in functie van kabel en lengte)
42 dbm -1 + 2.15 db = 43.15 dbm
Dit is dus vermogen uit onze zender:
42 dbm – 1.15 db = 40.85 dbm.
Omzetting van dBm naar Watt aan onze zender: Power out Tx: 12.16 Watt http://www.rapidtables.com/convert/power/dBm_to_Watt.htm
Voor diegene die het zelf willen berekenen.
How to convert dBm to watts
1dBm = 0.001258925W
So the power conversion of dBm to watts is given by the formula:
P(W) = 1W · 10(P(dBm) / 10) / 1000 = 10((P(dBm) – 30) / 10)
Example
Convert 43dBm to watts:
P(W) = 1W · 10(43dBm/ 10) / 1000 = 19.9526W
