2. FSK PHY recommendation • To facilitate ultra low power battery powered 802.15.4n devices for hospital sensor applications and other medical low power applications it is recommended that an FSK PHY is adopted. • Adoption of an FSK PHY would be in-line with current PHY amendments (802.15.4g & 802.15.4k) • An FSK PHY is also being proposed for 802.15.4q where power consumption is critical (#15-12-0634-01-004q) Example of FSK RX Example of FSK TX Andy Bottomley

3. Data Rates & Channel Proposal • 600kHz channelization • Provides multiple narrowband channels for interference mitigation • Filtered FSK • Modulation Index: TBD • Data rates: • Data rates in-line with current ‘g’ and ‘k’ FSKPHY proposals • 400kbps mode is otional Andy Bottomley
