Evolution of SCDMA system
SCDMA is a wireless access technology developed by
Beijing Xinwei Telecom Technology Incorporation.
McWill（Broadband
Narrowband
SCDMA
 Service: fixed voice
 Frequency:
400MHz/1800MHz
 Mainly applied in
rural areas
SCDMA）
 Service: data, voice
 Frequency: 1800MHz
 Supporting high
speed data access

Efforts on International BWA
Standardization
 In November 2009, CCSA put forwarded McWill(Multicarrier 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
Next Steps/Actions
Development of Standards
 Air interface, Equipment Specification, test method of new
generation of SCDMA.
 UWB air interface specification
 WLAN air interface
 Other technologies
Research
 Wireless ad-hoc network
 Zigbee
Cooperation
 Liaison with IEEE 802
 Cooperate with other SDOs
