Signal is above -65 dBm in each single room, generally it is at -fifty one dBm. When I incur that worst case drop of 24 dB from squeezing the cellphone, I fall all the way down to -83 dBm, which remains to be visualized as 5 bars.

For example, at one other take a look at location, sign without holding the telephone is -89 dBm, which is still displayed as 5 bars. Cup the phone, and you will fall all the way in which to -113 dBm. All the bars dramatically disappear one after the opposite, individuals think they’ve dramatically lost all of the signal, and you understand the remainder.
