The RF Module transceivers feature the LoRa TM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.
RF Module application to the residents of the centralized meter reading system。In order to achieve reliable and stable meter reading，We developed the standard interface of RF Module for acquisition equipment and metering equipment；
The anti collision mechanism of multi communication is realized, because the precision algorithm is designed；
We designed the RF Module’s self networking function，Further provide reliable acquisition through relay forwarding，In order to adapt to the acquisition of the farther distance and respond to more complex application environment.
