Message for the Solutions on 780MHz Band <month year> doc.: IEEE 802.15-<doc#> Nov. 2009 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 <author>, <company>

Possible Solution for Narrow Band (470 – 510Mhz) <month year> doc.: IEEE 802.15-<doc#> Nov. 2009 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.
