  2. Overview The Recent Investment on projects related to Smart Grid System The Possible Frequency Bands for Wireless Intelligent Power Control System Actions in CWPAN/CWSN Slide 2 Liang Li

  3. Recent Investment on Smart Grid • From 09-10, national investment to upgrade the Grid is $1600 B (RMB). • From 09 -- 12, the national investment on AMI is $100B (RMB) • From 09 – 12, the national investment for monitoring system on Power transmission is $100B (RMB) • From 09 -10, the national investment for Business&Operation supporting system for grid is $400B (RMB) Slide 3 Liang Li

  4. The Possible Frequency Bands for Smart Grid • Presently, most of investment for smart grid are on wired solution. • The Wireless SUN/Smart Grid have been promoted in recent years. • The possible frequency bands for wireless measurement instrument are: • 189.9 – 223 MHz, BW < 200KHz, Ptx (e.r.p)< 10mw. dfmax<100ppm • 470 -510MHz, BW < 200KHz, Ptx (e.r.p)< 50mw. dfmax<100ppm. TX transmission period is shorter than 5 sec. • 630-787MHz, BW < 200KHz, Ptx (e.r.p)< 50mw. dfmax<100ppm • The possible frequency bands for wireless control instrument are: • 314 – 316 MHz, 430-432MHz, 433-434 mhz BW < 400KHz, Ptx (e.r.p)< 10mw. • 779 – 787 Mhz Ptx (e.r.p)< 10mw. Slide 4 Liang Li

  5. Actions in CWPAN/CWSN • One Study group is organized at CWPAN/CWSN for Smart Grid and Meter Reading. • Some critical Issues: • Typical Usage Cases ? • Wireless Communication Environment ? • Operation Frequency Bands? • Chip Solution (PHY, MAC) ? • Create one group of national standards. • Cooperate to IEEE802.15.4G and members. • Similar working style as: IEEE802.15.4C/E vs. CWPAN ??? • Welcome any companies to attend CWPAN/CWSN meetings and join as members.
