Some articles refers to following levels: Once the Ec/Io is above ~ -7 dB, your connection is going to suffer. In a perfect world, where there is no true interference, the interference level is equal to the noise level resulting in anĮc/Io = 0 dB. This is a ratio of ' good' energy over 'bad' energy, or ' cleaness' of signal. Note that Power parametrs are expressed in dBm, Quality parameters in dBĮc/Io values - D ownlink carrier-to-interference ratio (signal quality) (dB) (2G, 3G & LTE) Although signal strength may appear to be adequate, throughput speeds may vary due to dependencies on cellular tower loads.There is no black/white answer to what constitutes a successful connection.Measured or reported values vary by modem, carrier, and network environment.Both Signal Strength and Signal Quality must be considered for successful cellular data connection.Physical barriers (mountains, buildings, trains, etc.).Signal going through a cellular repeater.There are many different factors that influence signal strength and quality, including but not limited to: RSRQ - Reference Signal Received Quality (signal quality) ( dB) (LTE only).RSRP - Reference Signal Received Power (signal power) ( dBm) (LTE only).RSCP - Received Signal Code Power (signal power) ( dBm) (3G only).

RSSI - Received Signal Strength Indication (signal power) ( dBm) (2G, 3G and LTE).

SINR - Signal-to-Interference-plus-Noise Ratio (signal quality) ( dB) (LTE only).

EC/IO - D ownlink carrier-to-interference ratio (signal quality) ( dB) (2G, 3G & LTE).

Signal values are defined by a few different measurements which vary even more for different service modes. This article explains how to basically interpret these ones. , display some parameters to help optimizing 2G/3G/4G connexions. The article resumes how to interpret the values without complete explanations about each parameter.Ī more detailled explanation of every parameters will be found in separate related articles.Īll devices (smartfones, 4G routers. This article applies for all 2G, 3G and LTE devices.
