Is it better to use RFM69HW/Nrf24L01 long-range on gateway?



  • I have not quite figured out if there is any advantage to use the long range variants of radios on the gateway. If I for example use a Nrf24L01 long range with antenna, will I get stronger readings? or is the long range versions only good for sending data?

    @Cliff-Karlsson In the long range variants, the LNA is for the receive side (does a better job amplifying the received signal) and the PA is to produce higher power output on the transmit side. I use a module with a LNA/PA for my gateway and also for nodes that are far away or behind a few walls.
