Can you help solving this Wireless problem?

[Giowizzy]

Let x be some location in two-dimensional space, and let A(r0) be the region of all other
points a distance r > r0 meters from x. Suppose that in the region A(r0), transmitters are
randomly placed with a uniform density of  transmitters per meter squared. There are no
transmitters outside of A(r0). That is, there are no transmitters less than a distance r0 from
x. If the received power from each transmitter at point x is given by Cr^-alpha for some alpha and
C, what is the total average power at x? What happens when alpha ≦2?

Thanks in advance

Are aou assuming that the transmitter signals are othogonal?

Yes, that's correct @FvM
