Dear all,
I'm working with CRN wireless antenna
kindly I need help in the SNR equation
suppose I have two antenna :
1- transmitting power =24 DBm
2- cable losses =1 DB at each side (Transmitter and reciever )
3- TX antenna gain 24 dbi
4- RX antenna gain =24 DBi
5- Distance between antennas =20 miles
6- FSPL=130 DB at 2.4 GHz (I calculated it )
7-assume RX sensitivity =-83 dbm
so the receiving power will be 23 dbm
but I need an equation to calculate the max distance that I can get with minimum SNR =-15 DB
?
kindly I went o Friis formula , but I cannot calculate the SNR ?
can I get it from the free FSPL ?

Sorry
receiving power will be 23 db
