antenna tilt
Hi,
I'm simulating a UMTS network in software. However I am unable to find a mathematical relationship that links the Power received at the receiving antenna of the UE and the Power transmitted by the Node B antenna, taking into account the tilt and azimuth.
Right now I can calculate my received power,Pr, using the Power transmit,Pt, the Gain of the transmit antenna,Gt, the Gain of the receive antenna , Gr, and the path loss, Lp.
Pr = Pt + Gt + Gr - Lp (all in dB)
But intuitively i know that if i direct my antenna to the sky (change the tilt), i should have a Pr of ZERO.
Is there any math expression that shows this
Cheers
