Go to FortiExtender GUI -> Dashboard and check for modem paramters RSRP, RSRQ, SINR, and RSSI.
RSRP, RSRQ, SINR, and RSSI are values that measure the quality and strength of a cellular signal. These values can be used to adjust the antenna of a router, modem, or repeater to get a stable and fast connection.
Refer to Display-rssi-signal-information to understand the recommended values for RSRP, RSRQ, SINR, and RSSI for optimum signal strength and quality LTE/5G internet speed.
RSSI. The Received Signal Strength Indicator (RSSI) represents the relative strength of a signal as it is received by a device. It is a relative value often expressed on a scale from 0 to -99, where higher values indicate a stronger signal.
RSRP plays a pivotal role in assessing the quality of cellular connections and is indispensable for optimizing network performance. Reference Signal Received Power (RSRP) is a vital metric used in wireless communication, particularly in cellular networks. It quantifies the strength of the received signal from the serving cell's base station. Essentially, it measures how strong the connection is between your device (for example: smartphone) and the primary cell tower connected to.
RSRQ. Reference Signal Received Quality (RSRQ) is a key parameter in wireless communication systems, particularly in the context of cellular networks like 4G LTE and 5G. RSRQ quantifies the quality of the received reference signal from the serving cell's base station (cell tower). This metric measures the signal's strength, similar to Reference Signal Received Power (RSRP), but it goes a step further by assessing the level of interference and noise in the received signal. Signal-to-Interference-plus-Noise Ratio (SINR) measurement indicates the RF channel quality. It assesses the quality of a wireless signal by considering three primary factors:
SINR is the ratio between the received power and the interference (plus noise). It is expressed in decibels (dB) and is a logarithmic measure that provides a clear picture of signal quality. Higher SINR values indicate a stronger, less noisy, and less interfered signal, resulting in better signal quality. |
