Have you ever noticed that when you’re in an area with no cell phone service, you can’t make a call, but when you leave that area and then make the call, you can go back into that area and the call will stay connected? I’m not talking about big no-service areas, but small areas of no coverage within larger areas that should have coverage.
For example, there is no cell phone service anywhere in the building where I work, except by the windows. If you stand by the window, you get a signal and can make calls, but if you move away from the windows, service drops and you can’t make a call. This happens 100% of the time. However, if you make a call while you’re standing by the window, the call will continue throughout the building (very clearly), no matter where you go. If you end the call, after a few seconds your signal will drop down to nothing and you can’t make calls anymore.
That’s just one example. I’ve noticed this happening everywhere. The last house I lived in was the same way. There was one room that didn’t get service, but if you started a call somewhere else, you could continue the call in that room with no problems.
Why is that? If the signal is strong enough to continue a call, why isn’t it strong enough to place a call? I’m hoping for an actual scientific answer, if there is one.
