That’s why many steel and concrete office towers with winding hallways have “dead spots” where cell signal strength is low.Ī cell phone is made to operate within -120 to -50 dBm with -50 being full strength. The cellular signal towers send the radio wave to your cell phone and then your phone sends it back generally speaking, the nearer you are to a tower, the stronger the signal between the two and the better connection for talking, texting, using apps, or browsing the web.īut there are other factors that can affect cell signal strength: namely the layout and construction materials of the building you are standing in.
