For maximum precision in signal level testing, switch your cell phone into Field Test Mode and see dB
parameter. The closer dB signal level to 0, the better cell phone reception you’ll get.
• -105 to -100 = Bad/drop call
• -99 to -90 = Getting bad/signal may break up
• -89 to -80 = OK/shouldn't have problems, but maybe
• -79 to -65 = Good
• Over -65 = Excellent
Your task is to get at least -79dB signal to ensure reliable communication and strong signal inside the
building.
