3. Background • Table 75e of the draft standard currently defines the MR-FSK radio specification in terms of a single generic list that takes no account of the different bit rates or regulatory requirements: Seibert (SSN), Jillings (Semtech), Kent (Analog Devices), Tuan Le (Texas Instruments)

4. Table 75 Parameters • Modulation Index Range / Tolerance • Reference is made to the following documents for informative purposes: • 802.15.4d (6.6b.2.3 GFSK modulation): • The deviation shall be between 70% and 130% of the nominal deviation. For the sequence 0101, the deviation shall be between 70% and 110% of the nominal deviation. For the sequence 00001111, the deviation shall be between 80% and 130% of the nominal deviation. • The section on 802.15.1 / Bluetooth in Document #10-0331-01 • ±30 % of the peak deviation for h = 1.0 • ±20 % of the peak deviation for h = 0.5 Seibert (SSN), Jillings (Semtech), Kent (Analog Devices), Tuan Le (Texas Instruments)

5. Table 75 Parameters • Frequency Tolerance / Stability • For licensed band communications frequency tolerance and stability is a matter for regulatory authorities • Clarification has been sought from regulatory bodies as to whether mains and battery powered endpoints are characterized as fixed / base or mobile stations Seibert (SSN), Jillings (Semtech), Kent (Analog Devices), Tuan Le (Texas Instruments)

6. Table 75 Parameters • System Time Stability • The parameter “system time stability” is not a PHY only function and shouldn't be part of the PHY standard. • TX Amplifier Rise / Fall Time • TX amplifier rise (and fall time) is included in both channel switching time and aTurnaroundTime. • Regulatory requirements relating to transient spectrum must be taken into consideration • TX amplifier rise / fall time is removed from the parameter table Seibert (SSN), Jillings (Semtech), Kent (Analog Devices), Tuan Le (Texas Instruments)

7. Table 75 Parameters • Channel Switch Time • Opinion was canvassed from implementers who may be subject to regulatory constraints concerning transient spectrum response • The definition of “channel switch time” is to be defined and agreed by the group • Define channel switch time as the response of the PLL for a frequency agile system to lock and settle within (tbd)% or ppm of the channel centre frequency? • ??? Seibert (SSN), Jillings (Semtech), Kent (Analog Devices), Tuan Le (Texas Instruments)

8. Table 75 Parameters • Sensitivity • Sensitivity, S, of the mandatory PHY data rate is normalized by the following equation, which applies to binary modulation: • Where • S0 = -90 dBm • R0 = 50 kb/s • R = bit rate in kb/s Seibert (SSN), Jillings (Semtech), Kent (Analog Devices), Tuan Le (Texas Instruments)

9. Table 75 Parameters • Adjacent / Alternate Channel Rejection • Both a definition of test methodology and values are to be addressed during modulation topic discussions • Symbol Rate Tolerance • Opinion was canvassed from authors of comments relating to symbol rate tolerance Seibert (SSN), Jillings (Semtech), Kent (Analog Devices), Tuan Le (Texas Instruments)
