Efforts on International BWA Standardization
In November 2009, CCSA put forwarded McWill(Multi-carrier Wireless information Local Loop) technology to ITU-R.
McWill was finally accepted as one BWA air interface of ITU-R M.1801 recommendation at ITU-R WP5A session.
Key Technical Characteristics• TDD/code-spread OFDMA(CS-OFDMA)• channel bandwidth of multiple of 1 MHz up to 5 MHz. • multiple antenna techniques • QPSK, 8-PSK, 16-QAM and 64-QAM for both uplink and downlink
Wireless ad-hoc network Zigbee
