The closer the RSSI value is to zero, the received signal is stronger.Īpart from the output power of the transmitter, the following factors mainly influence the RSSI: RSSI is measured in dBm and its value is a negative form. Since LoRaWAN supports bi-directional communication, RSSI is an important measurement for both gateways and end devices.
RSSI (Received Signal Strength Indicator) is a relative measurement that helps you determine if the received signal is strong enough to get a good wireless connection from the transmitter. This section contains information about two most commonly used signal strength indicators - RSSI and SNR.
In wireless communication, a receiver needs a good signal strength and a signal-to-noise ratio to separate the original signal from the modulated carrier.
