AS923-2
AS923-2 Everynet specifics.
Channels 0 and 1 are fixed and it's mandatory to be implemented on the end-device. Other channels configured by network server using MAC commands during integration stage (after join for OTAA or first uplink for ABP).
Uplink channels
| Channel | Frequency | Datarates | Type |
|---|---|---|---|
| 0 | 921.4 | 0,1,2,3,4,5 | Fixed |
| 1 | 921.6 | 0,1,2,3,4,5 | Fixed |
| 2 | 921.2 | 0,1,2,3,4,5 | |
| 3 | 921.8 | 0,1,2,3,4,5 | |
| 4 | 922.0 | 0,1,2,3,4,5 | |
| 5 | 922.2 | 0,1,2,3,4,5,6 | |
| 6 | 922.4 | 0,1,2,3,4,5 | |
| 7 | 922.6 | 7 | FSK |
By default, the RX1 receive window uses the same channel as the preceding uplink.
RX1 timeout = 1s
RX1 datarate offset = 0
The RX2 receive window uses a fixed frequency and data rate. The default parameters are:
921.4 MHz / DR2 (SF10/125KHz)
Datarates
| Index | Bandwidth | Spreading Factor | Paylaod Max Size | Physical bitrate [bit/sec] |

| 0 | 125 kHz | SF12 | 59 | 250 |
| 1 | 125 kHz | SF11 | 59 | 440 |
| 2 | 125 kHz | SF10 | 59 | 980 |
| 3 | 125 kHz | SF9 | 123 | 1760 |
| 4 | 125 kHz | SF8 | 230 | 3125 |
| 5 | 125 kHz | SF7 | 230 | 5470 |
| 6 | 250 kHz | SF7 | 230 | 12500 |
| 7 | FSK | 230 |
