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.

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
