"We had a perfectly good band at 305MHz for car remotes & the like, but big business wanted to import EU style 433MHz units which, due to the existing large market were cheap.
Under pressure from various "interest groups", ACMA "rolled over & played dead" & so the so-called Low Interference Potential Device (LIPD) category was born."
@jpm I'll buy 3, 1 for a gateway and 2 for whatever I end up doing with them. Got a moderately long pole from an old trampole (about 2-3m) that I can stick a box holding the gateway on top of, then mount it somewhere high.
@mightyspaceman ok a single-channel gateway is fine for a handful of devices, but you’ll need to fix everything to using a single channel (preferably not one of the TTN channels) and data rate, and you won’t be able to use your gateway with TTN. Multi-channel gateways start from about the $100 mark, with a large chunk of that being the Semtech SX130x radio DSP
