doc.: IEEE /0329r0 Submission Zhendong Luo, CATR March 2013 Background In China, the total bandwidth available for ac in 5 GHz was only 125 MHz (5,725 ~ 5,850 MHz). How to efficiently use this band was a critical issue for ac implementation in China. –R3.1.E in the 11ac spec framework points out that the 11ac draft specification shall include support for an efficient channelization in Chinas (5,725 ~ 5,850 MHz) spectrum. Although there are intensive discussions on this issue (esp. during IEEE ac meetings), there is still no appropriate solution. Slide 3
doc.: IEEE /0329r0 Submission Zhendong Luo, CATR March 2013 New progress of Chinas 5GHz spectrum regulation Recently, Chinas spectrum regulator, State Radio Regulatory Commission (SRRC), released a new spectrum (5,150 ~ 5,350 MHz) for wireless access systems, including Wireless LAN. The major requirements for the new spectrum are as follows. –Frequency range: 5,150 ~ 5,350 MHz –Transmit power: 200 mW (EIRP) –Maximum PSD: 10 dBm/MHz (EIRP) –Out-of-band emission: -80 dBm/Hz (EIRP) –For devices working in 5,250 ~ 5,350 MHz DFS shall be used. If TPC is not used, the maximum TX power and PSD shall be reduced by 3 dB. –The above requirements are basically same as ITU-R recommendation and European regulation. For more details, please refer to SRRCs Document 620. Now, the total spectrum of ac in China is up to 315 MHz. –5,150 ~ 5,350 MHz –5,725 ~ 5,850 MHz Slide 4

doc.: IEEE /0329r0 Submission Zhendong Luo, CATR March 2013 Summary China opens up a new 5GHz frequency band (5,150 ~ 5,350 MHz ), so that the total ac available spectrum is up to 315 MHz. An ac channelization for China is proposed to maintain compatibility and coexistence of ac devices throughout the world. Slide 7
