Current Products FOMA
N2001 by NEC, the standard phone, with an
improved color screen and -like the P2101V- no
external antenna. P2101V by Panasonic, outwardly
similar to the P503is, sports a camera that
besides taking stills allows it function as a TV
phone with other P2101V handsets. P2401 by
Panasonic, a PCMCI card designed for data
transmission up to 384Kpbs downstream and 64K
upstream.

Wireless Services Available in US

• Verizon - cdma2000 1x technology up to 144 kbit/s
  but users should see speeds of 40 to 60 kbit/s on
  average. data speed 19.2kbps or less locally
• Sprint - Plans to upgrade by 2004 GPSR and EDGE
• Cingular - plans to start CDMA2000 1x
• ATT - Deploying GSM/GPRS to 40 of its market,
  next to EDGE software to WCDMA
• T-Mobile - GSM/GPSR service
• Nextel Communications unknown plans

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

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.
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.

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.

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.
