Bad RSRQ (Reference Signal Received Quality) can be caused by high levels of interference from neighboring cells, excessive network load, or poor signal conditions due to obstacles like buildings or natural barriers. It may also result from suboptimal network configurations, such as incorrect antenna alignment or inadequate coverage.
How to improve RSRQ in LTE?
Improving RSRQ in LTE can be achieved by optimizing network configurations, such as adjusting antenna positions or orientations, reducing interference from neighboring cells, and balancing network load. Deploying additional cell sites or using advanced techniques like carrier aggregation and beamforming can also enhance RSRQ. Improving signal quality at the device level, such as by relocating the device to a better coverage area, can also help.
Fixing low RSRP (Reference Signal Received Power) involves improving the signal strength received by the user equipment. This can be done by increasing the transmission power from the base station, enhancing the coverage area by adding more cell sites, or optimizing the placement and orientation of antennas. In some cases, upgrading to devices with better reception capabilities or using external antennas can also address low RSRP issues.
SINR (Signal-to-Interference-plus-Noise Ratio) can be affected by several factors, including interference from neighboring cells, high network congestion, and environmental factors like buildings or terrain that reflect or block signals. Poor network planning, such as inadequate cell separation or overlapping frequencies, can also cause low SINR, leading to degraded signal quality and reduced data rates.
RSSI (Received Signal Strength Indicator) can be measured using various tools, such as specialized radio frequency (RF) measurement devices or built-in diagnostic features on mobile devices. These tools display the RSSI value, typically in dBm, allowing users to assess signal strength in real-time. Network engineers often use software applications that provide detailed readings of RSSI for troubleshooting and optimizing network performance.
