TD-SCDMA and TD-LTETD-SCDMA and TD-LTE

• TD-LTE positioned as next evolution in TD-

SCDMA family

• Estimates for TD-SCDMA market share unclear

– 1,000,000 subscribers as of July 09

• TD-SCDMA likely to be China-only

– Look at vendor investment as an indicator

• TD-LTE trials under way

– Timescales established for prototype, dual-mode and

multimode devices

– Several vendors already demonstrated working

network hardware to CMCC

• Trials against Aeroflex TM500 Test Mobile

The role of TD-LTEThe role of TD-LTE

• TD-SCDMA perspective

– Natural progression

• 3GPP perspective

– Commonality with FDD

• Vendor perspective

– Increasing use of software defined radio techniques

• Operator perspective

– Spectrum availability

– Flexible base stations

• Conclusion

– TD-LTE will be widely adopted in China and

internationally


Looking forwardLooking forwardLooking forward


Operator projections for 3GOperator projections for 3G

• 3m subs by end of 2009

• 50-80m subs by end of 2011

– Figures reduced from earlier in year

– Achieved 25% 3G market share in Q2

• 1.3m subs June 09

• 100m subs by 2010

• Official launch 1st August

• 200,000 subs by end Oct target

• 20m subs in first full year

– 2-3m iPhones potential in 2010


The LTE Chinese Mobile LandscapeThe LTE Chinese Mobile Landscape

2008/09 GSM continues to middle of next decade;

increasing rural westward focus

GSM

TD-SCDMA/WCDMA

LTE

2009/10 TD-SCDMA/WCDMA rolls out;

progressively penetrates most of population

2012/13 LTE starts; focus on eastern and major cities

• Technology is often first adopted on the east

coast and progresses west over time

• Old standards co-exist with new


One global standardOne global standard

• There is only one LTE

– Clear statement and drive from alliance of

Vodafone/Verizon/China Mobile

– Commonality of specifications and standards activity

– Vendors adopting software defined radio to make it a

reality

• But …

– … don’t forget about multiple spectrum allocations,

bandwidths and legacy handover requirements


Summary and final thoughtsSummary and final thoughts

TD-SCDMA

Here to stay

Will find a definite

role

TD-LTE

The next step for

CMCC…

…and for TD-

SCDMA

LTE

TDD vs FDD to

disappear

Both achieve

widespread use

What else?

The world’s biggest

market?
