•
•
•
•
•
•
•
•
* The relationship issue between WiMAX and 3G/3G evolution. It should be
clearly described and explained for the harmonic development relationship
between WiMAX , especially 16e(16-2005) , and 3G /3G evolution in order to
avoid mis-understanding and easy to get the helpful supporting from frequency
planning and market regulation ;
* The frequency planning support issue . It should try every effort to push the
Global /Regional and National frequency planning support work , especially to get
some progress from WRC-07 and the CPR Conferences ;
* Timely cost-effective , available and scaled chip manufacturing issue , especially
for the 16e (16-2005 ) Std. Chip manufacturing and the interoperation issues ;
* The important operators support issue . It should be through pragmatic chip
scaled manufacturing and reasonable market positioning works to attract global
important operators joining and supporting ;
* The issue on good coordination work with the IEEE 802 . 20x and 22 x Stds . and
the 16e Std evolution roadmap consideration ;
* The issue on attractive and cost-effective WiMAX network planning work,
especially for the station site-planning
and in-building network coverage
optimization works , etc.
* Policy and regulation issues on the relationship between public and professional
networks

WiMAX (cont.)
• C. Market Positioning ----- 6 Aspects
•
•
•
•
* From networks- viewpoint , WiMAxX can effectively support both
public networks and professional networks from fixed to mobile mode ,
especially it is very attractive for the e- government emergency
integrated response systems , military networks , as well as IP based
multi-services , such as media streaming and various video services ,
including video monitoring and supervising , etc;
* From operators – viewpoint , WiMAX can effectively support various
operators, such as the mobile operators for the basestaion connection,
backhaul and hot-zone bit rate enhanced mobility with middle moving
speed ; the old operators pushing the all-service transformation , such as
BT, FT, CT, CNC, etc; the so called Rabbits new operators with enough
capital investment ability , like Clearwire, PCCW, Altitude Telecom、
Iberbanda , Australia Wireless, etc.; the various professional operators ,
such as so called e-or digital- government based on WMAN requirement ,
as well as the emergency integrated response systems and military
applications , etc.
* From the coverage - viewpoint , WiMAX is WMAN based hot-zone and
effectively support both hotspot based Wi-Fi and WMAN based 3G/3G
evolution;

WiMAX (cont.)
• C. Market positioning (cont.)
•
•
•
•
* From mobility- viewpoint , WiMAX can support FMC mode , such as Fixed,
Nomadic,Portable, Simple mobility and Full mobility with moving speed less than
about 120 to 150 km/hr. , at the initial stage , the first 4 modes are important ;
* From terminal and roaming -viewpoint , WiMAX is mainly WMAN, PC and
data based, and including properly using PDA, as well as handset for WiMAX 162005 matured ;
* From services- viewpoint , WiMAX can provide large coverage and cost-effective
service mode to support rural communications and universal services , there is
also basically no backward compatible constraints , etc.
Therefore, WiMAX market positioning is basically complementary to 3G/ 3G
evolution and with good perspective.

pragmatic development implementation , NGN set vs. NGN sub- sets
//Packet based vs. IP based and /or all IP //Non-Connection faced vs.
and/or innovative connection characteristics faced //Networking evolution
--- overlapping , mixed and or integrated //From Softswitch to IMS and
FMC//Reasonable thinking about the IPv.6 development strategy , etc.
B. 3G and 3G Evolution issues ------* 3G license issue and release date strategy ,which is also relating to the
policy and regulation to WiMAX
*3G vs. 2G/2.5G+4G or 2G/2.5G + 802.xy issues
* Wi-Fi , WiMAX ( Wider –Fi) , WBMA( *MBWA or Mobile –Fi)
vs. 3G and 3G Evolution complimentary and harmonious development ,
* Important actions for 3G coming in China : scientific decision making,
market detailed dividing and importance of terminals and applications , all
direction innovation; IPR issue & FDD and TDD issue , as well as
license and frequency compensation design issues , etc. ;
