Market Requirement for Wireless Home Networks

• The forecasting of Chinese Home Appliance
  Association about Home Control Networks and
  devices is In 2005, the revenue over 10 billion
  RMB in China .
• The major Home and PC appliance manufactures
  (Such Haier, Lenovo) choose the wireless networks
  as their platforms for office and home network.

Open new Frequency bands for Wireless Home
Application

• The Chinese Radio Management decided to open new
  frequency bands for Short-distance wireless
  networks
• Conditions
• Not affecting to the other wireless communication
• Have the enough bandwidth

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.

5
The Progress of the Proposal

• Final evaluations from Wireless Industries,
  militaries, and Civic users
• Should be announce in this or next year.
