Data Rate and PHY¶
PHYs (also known as Modes) are defined by Wi-SUN Alliance. The following modes are supported by TI Wi-SUN FAN Stack. (All modes use 2-FSK.)
| Operating Mode ID | Mode ID | Data Rate | Modulation Index | Deviation |
|---|---|---|---|---|
| Mode #1a | 1 | 50 kbps | 0.5 | 12.5 kHz |
| Mode #1b | 2 | 50 kbps | 1 | 25 kHz |
| Mode #2a | 3 | 100 kbps | 0.5 | 25 kHz |
| Mode #2b | 4 | 100 kbps | 1 | 50 kHz |
| Mode #3 | 5 | 150 kbps | 0.5 | 37.5 kHz |
| Mode #4a | 6 | 200 kbps | 0.5 | 50 kHz |
| Mode #4b | 7 | 200 kbps | 1 | 100 kHz |
A quick way to test a PHY with a CC13x2 device is to use SmartRF Studio . A quick guide to getting started is found on SimpleLink Academy: Basic RX and TX SimpleLink Academy.
