  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Suggestions from China WSN/WPAN Standard Working Groups ] Date Submitted: [Sept, 2009] Source: [Tao Xiao, J Shen, Liang Li, Haituo Liu,, Betty Zhao] Company [SIMIT, Vinno, China Academic of Science, Huawei] Address [NO.865 Changning Road, Shanghai, 200050, China] Voice:[+86 21 6251 1070 ], FAX:[+86 21 6213 2314], E-Mail:[ jerryshen08@gmail.com, liang_1@yahoo.com ] Re: [IEEE 802.15.4g group] Abstract: According to the regular limitation of frequency in China Smart Grid. A proposal of Flexible DSSS PHY layer on 779-787MHz to meet the requirement and characteristic. Purpose: Presented to the 802.15.4g SUN Task Group for consideration 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. Tao Xiao, Liang Li

  2. Message for the Solutions on 780MHz Band • 779 – 787 MHz, Ptx< =10mw. Spurious emission is no larger than -36dBm • No frequency band limited on each channel • The Flexible data rates are welcome. • Expect the solution on 15.4G may be compatible to China National WPAN/WSN Standards. Tao Xiao, Liang Li

  3. Possible Solution for Narrow Band (470 – 510Mhz) • 470-510 MHz is narrow band. Each channel on this band is 200Khz. The max output power is 50mw. • The China Nation Standards for this band is on way. China WSN Std committee is in charge of creating or adopting standards on this bands for WSN, Smart grid and more applications. • Huawei, Vinno and SIMIT would support the sophistical, simple solutions on 470-510MHz, such as CPP, Joint-FSK • One united solution on narrow band on 470-510Mhz are recommended.
