4. Wireless Communications: Background: Per recitation, a wireless communication signal traveling from a cellphone tower to your phone bounces off numerous obstacles, causing multiple copies of the transmitted signal with different delays to arrive at your phone. These copies can add constructively or destructively, resulting in an effect called "multipath fading". The simplest (and perhaps most common) model for such is Rayleigh fading, which is a consequence of the (celebrated) Central Limit Theorem that we will leann later in the...

A typical cellular phone consumes an average of about 1.58 W of electrical power and operates on 3.80 V. (a) What average current (in A) does the phone draw from its battery? (b) Calculate the energy (in J) stored in a fully charged battery if the phone requires charging after 4.63 hours of use.
A solar power-plant can supply 1 million homes. The average energy consumption of a typical home is around 10,800 kWh per year. What is the capacity of this power plant in MW? Assume the capacity factor to be 0.44 for calculations.
How does cellphone service compare between different cities? The data stored in CellService represent the rating of Verizon and AT&T in 22 different cities. (Data extracted from "Best Phones and Service," Consumer Reports, January 2012, p. 28, 37.) At the 0.05 level of significance, is there evidence of a difference in the mean cellphone service rating between Verizon and AT&T? You need to download "CellService” data file.

Please do all questions... A cell phone battery manufacturer claims that one of their batteries for a particular cell phone will outperform a competitor's equivalent brand. To establish this claim, a researcher selected samples of the two brands of batteries and perform accelerated tests on them in the lab under identical conditions. A random sample of 55 of the manufacturer's battery was selected and placed on test. A corresponding random sample of 55 of the competitor's battery was also put...
