This strongly improves data transfer times and optimizes the usage of the limited bandwidth in the 868MHz ISM band in which the LoRaWAN gateways operate.
Our nodes periodically adapt spreading factor by instructions sent from the LoRaWAN network server. With this we help the operators to run as much as possible nodes in parallel and let them coordinate the nodes for optimal data rate and range. The nodes significantly benefit by the lower power consumption in higher data rate modes.
With SF7 transmit time is 20 times shorter than with SF12!
