Are there any generally accepted techniques for maximizing cell phone reception with regards to phone orientation? When I search for this question on Google I get "answers" that seem more opinion than anything. Any engineers in the house with definitive experience with this topic and confident answers to these questions? Do cell (mobile) phones generally have their antennas oriented up/down? If so, and assuming the emitters are up/down, is it safe to assume that you'll get better reception if your cell phone is in a vertical configuration? Or are there complications to this polarity issue? (I am guessing 'yes'!) When I am able to talk on my cell phone in my enclosed room, is it because the waves bounced off the walls and under the door (high reflective coefficient)? Or is it because they actually went through the walls (lack of absorption)? If the former, is it safe to assume that the polarity will be essentially random because of the various and multiple bounce angles? Do you know of more empirical approaches where there would be experiments done in which cell phones inside buildings at various distances from the emitting antenna would be placed at various locations and in various orientations to see which cases maximized reception? Perhaps we could find a general pattern which could lead to rules of thumb.
