Background
• In China, the total bandwidth available for 802.11ac in
5 GHz was only 125 MHz (5,725 ~ 5,850 MHz).
• How to efficiently use this band was a critical issue for
802.11ac 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
China’s (5,725 ~ 5,850 MHz) spectrum.
• Although there are intensive discussions on this issue
(esp. during 2010-2011 IEEE 802.11ac meetings), there
is still no appropriate solution.

New progress of China’s 5GHz spectrum
regulation
•
Recently, China’s 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 SRRC’s Document
[2012]620.
•
Now, the total spectrum of 802.11ac in China is up to 315 MHz.
– 5,150 ~ 5,350 MHz
– 5,725 ~ 5,850 MHz

802.11ac channelization for China
To keep compatibility and coexistence, 802.11ac channels for China
should be aligned with those in other regions.

Summary
• China opens up a new 5GHz frequency band (5,150 ~
5,350 MHz ), so that the total 802.11ac available
spectrum is up to 315 MHz.
• An 802.11ac channelization for China is proposed to
maintain compatibility and coexistence of 802.11ac
devices throughout the world.
