RFLoRaWAN Range Calculator: Estimate Distance and Link Budget
Advertisement
This page describes the LoRaWAN Range Calculator which estimates LoRa range (i.e., distance) based on the Egli model. It calculates the Link Budget and LoRaWAN range between a gateway and a LoRa node.
LoRaWAN Range Calculator Example:
LoRaWAN range calculator and LoRaWAN link Budget calculation :
INPUTS:
- Gateway antenna gain = 0 dBi
- Node antenna gain = 0 dBi
- Gateway height = 100 meters
- Node height = 10 meters
- Noise margin = 5 dB
- Operating Frequency = 868 MHz
- Gateway transmit power = 27 dBm
- Node Receiver sensitivity = -137 dBm
OUTPUTS:
- Link Budget = 159 dB
- LoRaWAN range (i.e., distance) from gateway to Node = 64087 meters
LoRaWAN Range Formula (Egli Pathloss Model)
The following Egli pathloss model based LoRaWAN Range formula is used to calculate the distance coverage of a LoRa Gateway to cover multiple LoRa nodes.
The range or distance calculation for other LPWAN technologies such as NB-Fi, Sigfox and Ingenu RPMA can also be done in a similar way as mentioned in this LoRaWAN range calculator. Rural regions will generally have higher range than city areas.
