doc.: IEEE b Submission July 2004 Liang Li, WXZJ Inc Slide 4 The Frequency band Proposal Near to the 900 and 868 MHz The Max Power should be very low. The bandwidth is not less 5 MHz Possible has the other frequency band for backing up this frequency band as the main band is prohibited in some areas.
