I have been experimenting with a dragino LG01 (single channel) LoRa Gateway. So far so good, but I’d like to take the next step and setup a LoRaWAN Gateway.
I have read this Newbie which gateway AU post but still have some questions.
I’ve sort of narrowed my search down to these devices (but am open to suggestions):
The RAK 7258 talks about 8 RX and 1 TX channels. The LG308 and LPS8 talks about emulating 49 demodulators (is that like channels?) but also mentions 10 programmable parallel demodulation paths. What exactly does that mean?
How does this relate to the AU frequency plan, which seems to list 9 uplink and 8 downlink channels in the AU915-928 section? Specifically, how does the AU plan relate to these devices which in the case of the RAK device which supports 1 TX channel or does it mean it can TX on all 8 (9?) channels, but just one at a time?
Also, what does the Note at the bottom of this section about “The Things Network uses 2nd Sub-Band only (channels 8 to 15 and 65)” mean?
Finally, on the channels topic, how is uplink channel 9 (917.5MHz) used? It seems like this channel is somehow special as it is:
- right in the middle of the uplink spectrum (916.8-918.2 MHz);
- is listed last and
- has a different bandwidth(?) specification to all of the others in the AU region?
Of the above 3 gateways, how have other users experiences been? Has anyone had a “if I’d only known X, I never would have used device Y (from the above list)” or similar type of experience they would be willing to share?
Hopefully these questions are not too stupid, but I’m not getting a clear picture (signal? ) about some of the above topics - or am I just overthinking this and any one of the above gateways will be just fine???
TIA for any feedback.
