    "abstract": "We study the distributions of dropped calls rates for different wireless\n(cellular) carriers in different markets. Our statistics comprises over 700\ndifferent market/carrier combinations. We find that the dropped calls rates\ndistribution is very close to lognormal. We derive an equation for the most\nprobable dropped calls rate for particular carrier in particular market, which\ndepends on the number of dropped calls observed, total number of calls and the\nparameters of the lognormal distribution. We apply this analysis to blocked and\n\"no service\" calls as well.",
