Message for the Solutions on 780MHz Band

• 779 787 MHz, Ptxlt 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.

Possible Solution for Narrow Band (470 510Mhz)
Nov. 2009

• 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.
