RSSI stands for Received Signal Strength Indicator, which is a measurement used to indicate the strength of a received radio signal. It is typically expressed in decibels (dBm).
An RSSI value of -48 dBm indicates a strong signal. Generally, RSSI values can be interpreted as follows:
- -30 dBm to -50 dBm: Excellent signal strength. The connection is likely to be very stable with high data rates.
- -50 dBm to -70 dBm: Good signal strength. The connection should be stable and capable of reasonable data rates.
- -70 dBm to -85 dBm: Fair signal strength. The connection may be unreliable, and data rates may be reduced.
- -85 dBm and lower: Poor signal strength. The connection may frequently drop or be unusable.
In summary, an RSSI of -48 dBm suggests that the device is receiving a strong signal from the wireless network, which should result in a reliable connection and good performance.
