    Hello
    The US915 Hybrid channels configuration has only one BW500 frequency,
    Set to be used on DR4 only.
    does that means that all close end unit with good RF conditions,that ware set to DR4 by the Gateway, will work with the same one frequency all the time?
    Thank’s Amir

    That is correct.

    A single gateway card can listen on 8 – 125 kHz channels, 1 – Fixed Lora datarate channel (US:DR4:SF8BW500) and 1 – FSK channel (EU) simultaneously.

    If max datarate is set to DR4 then the close end-devices will use DR4 on only one channel.

    Of course the effective bandwidth of one 500 kHz channel vs eight 125 kHz channels is halved so the datarate increase has a trade-off.

    It may be best to use DR3 as max datarate for ADR and use DR4 for special cases.
