  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title:[Modulations on Chinese 779Mhz and 470Mhz Bands] Date Submitted: [12 May 2011] Source:[Liang Li, Betty Zhou] Company: [Vinno, Huawei] E-Mail: [liangli@vinnotech.com] Re: [] Abstract: [] Purpose:[] Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P802.15. Steve Jillings, Semtech

  2. Modulation on 470MHz Band On 470- 510 Mhz Band, one pending national (AMI) Std: GB/T19882-222 “ Automatic Meter Reading System- Part 2-2-2： Wireless meter reading system- Wireless Ad hoc Network Communication Protocol “ • Band and Data Rate • Band(MHz) Modulation(b/s)DF(KHz)Power • 430-432 FSK/GFSK 38400 19200 ±50 10 • 433-434.79 FSK/GFSK 38400 19200 ±50 10 • 470-510 FSK/GFSK3840019200±5050 Steve Jillings, Semtech

  3. Modulation on 780M On 779-810Mhz Band, one national Std: GB/T15629-2010(IEEE802.15.4c) Modulation: OQPSK, and MPSK. Steve Jillings, Semtech

  4. Conclusion For IEEE802.15.4G being smoothly “merged” by Chinese std group/committee and products with 4G being manufactured and accepted in China, CWPAN/CWSN agreed that it is an easy way to keep the current modulations on 470Mhz and 780MHz bands Steve Jillings, Semtech
