What's RSRP, SINR & RSRQ

RSRP, SINR, and RSRQ are three important parameters used to measure the quality and strength of the signal in a wireless communication system, specifically in LTE (Long-Term Evolution) networks.

1. RSRP - Reference Signal Received Power: RSRP measures the strength of the signal received from a specific cell in the LTE network. It is measured in dBm and is a critical parameter for cell selection and handover decisions.

2. SINR - Signal-to-Interference plus Noise Ratio: SINR measures the quality of the signal received from a specific cell and measures the ratio of the desired signal power to the interference and noise power. It is measured in dB and is a critical parameter for determining the data rates that the network can support.

3. RSRQ - Reference Signal Received Quality: RSRQ measures the quality of the received signal and is a ratio of RSRP to the received signal quality (RSRQ). It measures the level of interference from neighboring cells and is an essential parameter for handover decisions.

In LTE networks, these parameters are used to optimize the network's performance and ensure that the signal is of sufficient strength and quality for effective communication. Network operators use these parameters to troubleshoot network issues and optimize network performance.
