Consider a cellular system with circular cells with radius equal to 100 meters. Assume propagation follows the simplified path loss model with K = 1, d0 = 1 m, and γ = 3. Assume the signal experiences log-normal shadowing on top of path loss with σψdB = 4 as well as Rayleigh fading. The transmit power at the base station is Pt = 100 mW, the system bandwidth is B = 30 KHz, and the noise PSD is N0 = 10−14 W/Hz. Assuming BPSK modulation, we want to find the cell coverage area (percentage of locations in the cell) where users have average Pb less than 10−3.

Find the received power due to path loss at the cell boundary.

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
