1 China MM-Wave (CMMW) Study Group - Introduction of CMMW PAR and 5C
April 2007 doc.: IEEE /0570r0 May 2012 China MM-Wave (CMMW) Study Group - Introduction of CMMW PAR and 5C Date: Authors: Xiaoming Peng, Eldad Perahia Eldad Perahia, Intel Corporation

2 Overview of China 60 GHz issues
The 60GHz frequency band allocated in China is only 5 GHz bandwidth from 59-64GHz which is smaller than the typical 7-9 GHz bandwidth allocated in other countries. The current band plan considered in ad uses channels with 2.16 GHz bandwidth which gives only 2 logical channels for networking when it is operated in China. This may limit the usage of ad products in China market. USA, Canada, Korea Europe Japan China Australia Xiaoming Peng, Eldad Perahia

3 Overview of China 45 GHz frequency band
April 2007 doc.: IEEE /0570r0 Overview of China 45 GHz frequency band May 2012 After communicating with China Radio Management Authority, CWPAN (SG5: Q- LINKPAN) has submitted the final request of the unlicensed band in the GHz for approval Path 45 GHz – about 2.5dB lower than 60GHz: TX power: < +20 dBm (Antenna port) Frequency tolerance: 100×10-6 Due to the better propagation property in the GHz frequency band than the 60 GHz frequency band, it allows the operation of product over more frequency band and opens up more application scenarios than ad for larger coverage and portable devices with lower-power. Final Request of China 45GHz spectrum Around 60 GHz 45 GHz Propagation Property between 45GHz and 60GHz Xiaoming Peng, Eldad Perahia Eldad Perahia, Intel Corporation
