This page describes Wi-SUN PHY Modes covering Symbol rate and Modulation Index used in Wi-SUN Physical Layer. Wi-SUN PHY (Physical layer) specifications use IEEE 802.15.4g, 802.15.4u and 802.15.4v standards.
Following are the features of Wi-SUN IoT technology:
- Standard: Wi-Sun (802.15.4g)
- Frequency: ISM < 2.4GHz
- Bandwidth (Max.): 200 kHz to 1.2 MHz
- Data rate: 50 kbps to 1 Mbps
- Modulation: FSK ,OFDM, OQPSK
- Range: 1000 meters
- Network: WPAN
- Applications: FAN and HAN Smart Utility Networks, Smart Grid, Smart Metering
Wi-SUN PHY Modes: Symbol Rate and Modulation Index
The following table outlines the different PHY modes, their corresponding symbol rates, and modulation indices used in Wi-SUN.
