3G wireless technology promises high-speed data and mobile streaming video. However, implementation costs have dampened enthusiasm. Carriers had to pay billions for spectrum licenses and building new 3G infrastructure is expensive. Additionally, early 3G devices were costly for consumers, with handsets around $300 and monthly service fees up to $90. Despite challenges, major carriers are working towards 3G as it provides access to the huge and growing mobile market, especially in countries like China.

8. Reasons for delay
 Regulations
 Developing Technology
 Financial Considerations

9. 3G Technology:
-UMTS (W-CDMA,TD-CDMA) & CDMA 2000
UMTS- Europe, Japan, China
CDMA2000 – US, Korea

10. 3G Technology:
-UMTS
– W-CDMA (FDD)
Duplex
– TD-CDMA (TDD)

11. 3G Technology:
-CDMA 2000
– 1XRTT (144 Kbps)
– 3XRTT (2Mbps)
– 1X EV (Evolution)
 1X EV-DO ("Data Only"): Separate
frequencies for data and voice.
 1X EV-DV ("Data and Voice"): integrate voice
and data on the same frequency band

12. W-CDMA vs. CDMA 2000
– W-CDMA: Brand new network, requires
new spectrum.
– CDMA2000: Build on the old CDMA
network, deploy fast, flexible in spectrum,
more efficient for both voice and data,
base station synchronization, existing in
Korea.

13. Standardization:
 3GPP- UMTS
 3GPP2- CDMA2000
Global Roaming

14. Spectrum:
ITU Suggests 1885-2025 MHz and
2110-2200 MHz for 3G service.
Europe and Asia: Available
US: N/A

16. Spectrum:
 Regulators
FCC (Federal Communication Commission)
NTIA (National Communications and Information
Administration)
 US, until September-2004
 Demand is high, spectrums are limited
 Carriers need the license from government
to run the business.

17. Is 3G a wireless
marvel or an
investment disaster?
 The 3G technology promises high-
speed data, mobile streaming video and
anytime-anywhere access.
 But implementation costs have
significantly dampened enthusiasm.

18. Spectrum cost
 Limited spectrum
 Major carriers have to pay the $16
billion for getting the license from
government auction of spectrum
licenses.
 the prices some companies paid
for licensing are affecting their
ability to invest in 3G
infrastructure.

19. Technology cost
 WCDMA or CDMA 2000
 Example of Korea and Japan
 The situation is similar in the U.S.
 Sprint PCS and other CDMA operators
on the path to cheaper upgrade than
those operators on the path to W-
CDMA.
 So the CDMA2000 has time
advantage, W-CDMA has scale. but
this scale advantage need time.

20. Price compare

21. The existing networks are determining what
path the carriers are choosing to get to 3G.
· North American wireless carriers
Carrier Path to 3G Wireless subscribers
(voice & data)
Sprint PCS CDMA 2000 90 million
Verizon Wireless CDMA 2000 26 million
Cingular WCDMA 19 million
AT&T Wireless UMTS & WCDMA 12 million
VoiceStream WCDMA 3 million

22. Expensive devices and
service to consumers
 In addition to 3G's already expensive
tag, the end user devices to be used in
conjunction with the next generation
of wireless infrastructure are also
expected to be expensive. It's
estimated that 3G-enabled handsets
will cost $300, in addition to monthly
service fees that could be as high as
$90.

23. Handsets price

24. Huge market
 Despite these hurdles, major
carries and equipment vendors
have mostly laid out their
blueprints for migrating toward
3G technology.
 China already is the world's largest
cell phone market, with 180 million
subscribers and growing.

25. Current wireless users

26. Conclusion
There are several factors that delay
the deployment of 3G systems
worldwide, but it is such a large
market issue companies will continue
to use resources in developing 3G
technologies.
