Hello,
I have an RF transmitter with an ERP of -10dBm, and a 0dB gain antenna.
Since I don't want to interfere to other receivers around me I want to calculate the maximum range I might effect.
A few assumptions:
1. The other receivers sensitivity is -174 dBm/Hz (a strict assumption, because I want to take the worst case).
2. ERP of transmitter (as mentioned above): -10dBm.
3. antenna gain= 0dB, no cable loss or polarization loss.
I used the sensitivity equation: S=ERP-22-20log(R)+20log(c/f), but for some reason I think I'm doing something wrong.
c=3*10^8
f=400*10^6 ,(400 MHz).
Am I using the right equation?
What is the maximum effected range?
Thank you,
IK
