do you ever raise your arm to the sky in an effort to get cell phone service does putting our arms up actually help us get bars you might think putting your arm up will get your phone closer to the cell tower or improve your chances of picking up a signal in reality cell signals are more or less homogeneous and surround us if you don't have signal now the length of your arm won't be enough to get it I talked to Lu Zhang a professor in the Department of Electrical and Computer Engineering at Rice University about this behavior I think generally things say yeah it doesn't help that much you may think that the cellphone signal is like spotlight when you're on a stage it's not it's already become a few safe therefore when you change raise your hand or change your orientation effects versus mode in general I don't I don't think it helps a lot with that said walking a half block or so can help especially if you're in a city because if you're in a city you're receiving signals as they bounce off buildings so walking around a bit could change how the signal gets to you as for the actual phones themselves there isn't much you can do to change the service you get the manufacturers already do rigorous testing around cell signal and barring fluke situations like antenna gate with iPhone 4 they do a good job of maintaining calls of course the service provider you have can also affect your service because now all providers are created equal but if you're in a dire situation and you need a cell phone service Lin recommends getting on your feet and walking look there situation if you don't have good quality is because a lot of people on your value like the crowded concert walking a few meters wouldn't solve the problem but if you happen to be in a urban Canyon like in downtown area with other buildings right it could potentially help our cause or your indoor that there's some location that you don't have good reception maybe walk a little bit the more you what maybe the better chance you have a solution you heard the man get out there maybe you'll wander into service you
