RSRP values - Reference Signal Received Power(signal power) (dBm) (LTE only) Note : RSCP parameter in 3G becomes RSRP in LTE While RSCP can be measured in principle on the downlink as well as on the uplink, it is only defined for the downlink and thus presumed to be measured by the UE (User Equipment) and reported to the Node. It denotes the power measured by a receiver on a particular physical communication channel.

#How to check lte interference in actix code#
RSCP - indicates the Received Signal Code Power RSCP values (3G only) - Received Signal Code Power (signal power) (dBm) (3G only) RSSI = wideband power = noise + serving cell power + interference power. RSSI for LTE is a calculated from several other signal related measurements. RSSI in LTE - Received Signal Strength Indication (signal power) (dBm) (2G, 3G and LTE) The RSSI standard values for 3G are basically the same as for 2G. RSSI values in 3G - Received Signal Strength Indication (signal power) (dBm) (2G, 3G and LTE) RSSI is a negative value, and the closer to 0, the stronger the signal. RSSI values in 2G - Received Signal Strength Indication (signal power) (dBm) (2G, 3G and LTE)ĢG (GSM) Signal strength is defined by only one value: RSSI - Received Signal Strength Indicator The closer to 0 dBm, the stronger the signal The RSSI of the modem is indicated by a negative dBm value. RSSI represents the entire received power including the wanted power from the serving cell as well as all cochannel power and other sources of noise. RSSI measures both the usable signal and the noise in a single figure. RSSI ( Received Signal Strength Indication (signal power) (dBm) (2G, 3G and LTE) In 802.11 networks, re-transmissions adversely affect throughput and latency. Data corruption and therefore re-transmissions will occur if the received signal is too close to the noise floor. For example, if a radio (client device) receives a signal of -75 dBm and the noise floor is measured at -90 dBm, the SINR is 15 dB. SINR is not actually a ratio but the difference in decibels between the received signal and the background noise level (noise floor). SINR is commonly used in wireless communication as a way to measure the quality of wireless connections. SINR values - Signal-to-Noise Ratio (signal quality) (dB) (LTE only) Once the EC/IO is above ~ -7.0 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 an EC/IO = 0 dB. 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)

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.
