QuickStudy: Why your cell phone won’t connect
It happens to everyone: You try to make a cell phone call and find you have no service. What’s the problem? The device in your hand is more powerful than a full-blown computer from just a few years past; why can’t it connect? Coverage Limits Unfortunately, computing power doesn’t relate directly to connectivity. Cell phones only work over short ranges and can’t transmit more than about eight miles. Most urban and well-populated areas have plenty of cell sites, so coverage isn’t a problem, but sometimes there’s no cell service within range. Cellular networks use a series of base stations, each covering a given area known as a cell, and these cells are designed to overlap so as to provide total coverage for a given geographical area. When you switch your phone on, it connects to the nearest base station; as you move from place to place, you may get closer to a different base station, and the network automatically switches your phone to the new cell. But if a base station is already working at full capacity, it can’t accept your signal, and the result is a dropped call. Your phone just won’t work in that place at that particular time. Dropped calls can also happen in areas where cells don’t overlap. Read today’s complete QuickStudy at Read More
