July 2004 doc. : IEEE 802. 15 -04 -0370 -00 -004 b Open new Frequency bands for Wireless Home Application • The Chinese Radio Management decided to open new frequency bands for Shortdistance wireless networks – Conditions: • Not affecting to the other wireless communication • Have the enough bandwidth Submission 3 Liang Li, WXZJ Inc

July 2004 doc. : IEEE 802. 15 -04 -0370 -00 -004 b 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. Submission 4 Liang Li, WXZJ Inc

July 2004 doc. : IEEE 802. 15 -04 -0370 -00 -004 b The Progress of the Proposal • Final evaluations from Wireless Industries, militaries, and Civic users • Should be announce in this or next year. Submission 5 Liang Li, WXZJ Inc
