  2. Power and Spectrum EfficientPHY Proposal for 802.15.4g IEEE 802 Plenary Meeting 15th July 2009, San Francisco Khanh Tuan Le Khanh Tuan Le (TI)

  3. Introduction • Efficient working technology with focus on the user requirements, available frequency spectrum and applicable regulations for systems operating in the license exempt frequency bands • This is an update of the submitted final proposal IEEE 802.15-09-0290-02-004g “Power and Spectrum Efficient PHY Proposal for 802.15.4g” Khanh Tuan Le (TI)

  4. Summary of the updates Khanh Tuan Le (TI)

  5. Modulation and Data Rates • Modulation format: • 2-GFSK and 4-GFSK, BT=0.5 • Data rates: • (R1) 50 kbps : 2-GFSK, modulation index 0.9 • (R2) 100 kbps: 2-GFSK, modulation index 0.9 • (R3) 200 kbps: 4-GFSK, modulation index 0.3 Rb = 50 * 2N kbps for N= 0,1,2 Khanh Tuan Le (TI)

  6. Frequency Availability at 868 MHz • FHSS less encouraging at 868 MHz than at 915 MHz • Use of the entire 7 MHz band limits the channel spacing to less than 100 kHz regardless of FH or non-FH  Maximum data rate constraint • FH does not enable higher transmit power • Duty cycle or LBT also apply for FH systems • Mostly single channel systems in operation today with duty cycle compliance • Availability of multiple channels will be a significant improvement • ’Creative’ (slow) hopping or frequency agility • Larger channel spacing to enable higher data rates Khanh Tuan Le (TI)

  8. 863-870 MHz ISM Band in Europe (2) • Frequency Band: 863-870 MHz • Frequency sub-bands and allowed max output power: • 868.00-868.60 MHz (600 kHz): 25 mW / +14 dBm (g1) • 868.70-869.20 MHz (500 kHz): 25 mW / +14 dBm (g2) • 869.40-869.65 MHz (250 kHz): 500 mW / +27 dBm (g3) • Sub-band channel spacing: 250 kHz • Number of channels: 5 • Channel center frequencies: • 868.175 MHz and 868.425 MHz • 868.825 MHz and 869.075 MHz • 869.525 MHz • Adaptive Frequency Agility (AFA) with Listen-Before-Talk (LBT) Khanh Tuan Le (TI)

  9. 863-870 MHz ISM Band in Europe (3) • The center frequency of these channels is defined as follows: • Fc = 868.175 + 0.25 k in megahertz, for k = 0,1 • Fc = 868.325 + 0.25 k in megahertz, for k = 2,3 • Fc = 869.525 in megahertz, for k = 4 where k is the channel number Khanh Tuan Le (TI)
