EcIo= Energy per Chip over Interference.
As a general rule:
EcIo is considered good if -10dB < EcIo < -2dB.
EcIo is acceptable if -16dB < EcIo < -10dB.
EcIo is weak if ECIo < -16dB
RSSI=Received Signal Strength Indicator
RSSI is considered good if RSSI > -80dBm,
RSSI is acceptable if -95dBm < RSSI < -80dBm,
RSSI is weak if RSSI < -95dBm.
RSCP=Received Signal Code Power.
RSCP can only be judged according to RSSI and EcIo.
In any point on the map (for a specific Scrambling Code and a specific DL UARFCN) following equation is true: RSSI=RSCP-EcIo (in dB)
