Definition
RSSI (Received Signal Strength Indicator) measures the power level of received radio signals, typically expressed in dBm. For ERRCS testing, RSSI measurements at grid points throughout a building determine compliance with coverage requirements. Most codes require minimum -95 dBm signal strength for both inbound and outbound signals.
