1 doc.: IEEE XXX g Submission May FX. Fu, J.ShenSlide 1 Project: IEEE P Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [PHY Layer Discussion for Chinese NB-Frequency Bands] Date Submitted: [30 June, 2009] Source: [Zhuang Zhao, Xiao Tao, Liang Li, Haitao Liu, Betty Zhao ] Company [Chinese Academy of Sciences, Vinno, Huawei, Wuxi Mirco-Nano Sensor Networks R&D Center] Address [Beijing] Voice:[ ], FAX:[ ], Re: [IEEE g group] Abstract: PHY Layer Discussion on NB Frequency Bands Purpose:Presented to the g SUN Task Group for consideration Notice:This document has been prepared to assist the IEEE P It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s).

2 doc.: IEEE XXX g Submission Several Authorized NB in China The possible frequency bands for wireless measurement instrument are: – 223 MHz, BW < 200KHz, Ptx (e.r.p)< 10mw. dfmax<100ppm MHz, BW < 200KHz, Ptx (e.r.p)< 50mw. dfmax<100ppm. TX transmission period is shorter than 5 sec MHz, BW < 200KHz, Ptx (e.r.p)< 50mw. dfmax<100ppm The possible frequency bands for wireless control instrument are: 314 – 316 MHz, MHz, mhz BW < 400KHz, Ptx (e.r.p)< 10mw. May FX. Fu, J.ShenSlide 2

3 doc.: IEEE XXX g Submission Suggestion for NB PHY Layer Data Rate is variable Variable transmit power Bandwidth <= 200kHz Multiple-Channel, Channel Hopping (Optional) FSK or GFSK –Adjacent concerns –Processing Gain –Better out of band emissions

4 doc.: IEEE XXX g Submission United Preamble pattern Payload size controlled by MAC up to 2047 octets per PSDU CRC Error Detection and practical security procedure Adopting most of IEEE E and compatible to IEEE CSMA or Listen Before Talk (LBT) Suggestion for NB PHY Layer
