Let's say we have a path Length AC. Point A transmits a signal at Ptransmit.
From Friis' Path Loss formula: (assumming Gain for receiver and transmitter antennae are 1.)
##P_{received} = P_{transmit} (\frac{λ}{4π* LengthAC})^2##
,when point C contains the receiver.
What if I divided this into two segments. They should still have the same answer right?
Let's say point B is somewhere between A and C.
Theoretically, the path loss in AB plus the path loss in BC should equal the path loss in AC. If I do this using the formula.
##P_{received at B} = P_{transmit} (\frac{λ}{4π* LengthAB})^2##
##P_{received at C} = P_{received at B} (\frac{λ}{4π* LengthBC})^2##
Combining these two should get me to the total of the equation before. How should I combine them? I couldn't just multiply or add them together. The math would be messy. Am I missing some assumptions here?
