3. doc.: IEEE 802.11-13/0176r0 Submission Abstract This document is to describe the proposed Channelization for Chinese 60GHz band and 45 GHz band for 802.11aj This contribution has been discussed in CWPAN group Jan 2013 Slide 3Bo Sun, ZTE/CWPAN

4. doc.: IEEE 802.11-13/0176r0 Submission Background – Chinese 60GHz Spectrum The released 60GHz spectrum in China only has 5GHz bandwidth, corresponding to channel 2 & 3 used in IEEE 802.11ad/WiGig. There will be only 2 logic channels available for 802.11ad device to formulate networks in China which may limit the performance of 802.11ad device 4 USA, Canada, Korea Europe China Japan Australia Jan 2013 Bo Sun, ZTE/CWPAN

5. doc.: IEEE 802.11-13/0176r0 Submission 45 GHz spectrum in China – pending for approval After communicating with China Radio Management Authority for a few rounds, CWPAN has submitted the final request for the unlicensed band in 43.5-47.0 GHz for approval (pending for approval) Bandwidth (B 0 ) Transmit mask: Refer to IEEE 802.11ad TX power: < +20 dBm (Antenna port) Frequency tolerance: 100×10 -6 Path Loss @ 45 GHz – about 2.5dB lower than 60GHz: 5 Transmit mask Final Request Initial Request Jan 2013 Bo Sun, ZTE/CWPAN

7. doc.: IEEE 802.11-13/0176r0 Submission Proposed Channelization for 60GHz bands for 802.11aj (1/2) Advantage of the proposed channelization for 60GHz bands in China  China only has 5GHz bandwidth available in 59-64GHz  only has two logical channels if only use 2.16 GHz BW  Further divide 2.16GHz band used in 802.11ad channelization into two 1.08GHz sub-bands, then it become 6 logical channels: 2 bands with 2.16GHz bandwidth (Channel 2 & 3), 4 bands with 1.08GHz bandwidth (Channel 5, 6, 7, 8) ； 7 Channelization for 60GHz bands in China Jan 2013 Bo Sun, ZTE/CWPAN

8. doc.: IEEE 802.11-13/0176r0 Submission Proposed Channelization for 60GHz bands for 802.11aj (2/2) Support dynamic bandwidth  Capable of supporting wider applications for lower power, e.g. Smart Phone, Tablet etc.  The impact to implementation in RF, Analog baseband is very minimal. It only needs to add to support four more new center frequency in PLL design, a new filter to support 1.08GHz in analog baseband etc ；  The support of dynamic bandwidth in the channelization for China 60GHz bands provides the basis of keeping the interoperability with 802.11ad device ； 8 Channelization for 60GHz bands in China Jan 2013 Bo Sun, ZTE/CWPAN

9. doc.: IEEE 802.11-13/0176r0 Submission Proposed Channelization for 45GHz band (1/2) Three channel bandwidths proposed: 1.08GHz 、 540MHz and 270MHz. A basic diagram is as follows: Slide 9 Jan 2013 Bo Sun, ZTE/CWPAN

10. doc.: IEEE 802.11-13/0176r0 Submission Proposed Channelization for 45GHz band (2/2) A minimum of 270MHz channel bandwidth can be used as a fundamental channel, with a maximum of 12 independent channels available. With 540MHz channel bandwidth, up to 6 mutually independent channels available. With 1.08GHz channel bandwidth, up to 3 mutually independent channels available. Slide 10 Jan 2013 Bo Sun, ZTE/CWPAN
