Three Generations of Cellular Systems
  • 1983-1992 First Generation (1G) Analogue --US
    dominance (AMPS)
  • a) Mobile voice communications
  • b) No data service
  • 1992- 2001 Second Generation (2G) Digital
    (circuit-switched networks) --Western Europe
    dominance (GSM)
  • a) Digital voice service
  • b) One-way data transmissions only
  • c) Enhanced calling features (called ID)
  • 2001-2008/10 Third generation (3G) Multimedia
    (packet switched networks) --a single flexible
    standard (W-CDMA)
  • a) Superior voice quality
  • b) high-speed mobile internet (Up to 2M
    bit/sec always-on data)
  • c) Broadband data services like video
    and multimedia
  • d) Enhanced roaming
  • The sequence of the phases has been similar, but
    the timing has differed. (Steinbock, 2003,
    p.211)
  • New policiesmonopoly? competition
  • Innovationproprietary patents? openness and
    standardization
  • Marketsoriginal demand? replacements
    (Steinbock, 2003, p. 208)

Social Necessity of Technologies Transitions in
Cellular Industry
  • The transition from 1G to 2G was primarily
    motivated by 2Gs
  • a) more efficient use of radio spectrum
  • b) increasing market demand for wireless
    telephony.
  • The 3G system came into being due to
  • a) the demand of new features
  • b) more efficient services desired by the
    highly successful 2G cellular phone markets in
    the early 1990s.
  • The development of each generation is aimed to
    provide higher data rates and additional
    capabilities, which can be viewed as a kind
    remediation on the older technology.

The sequence of the phases has been similar, but
the timing has differed. (Steinbock, 2003, p.211)

and Japan

How U.S. lost industry leadership in wireless
communications
  • Delayed 3G governing policy
  • 196882 Industry wars between FCC, DoJ, ATT,
    RCCs, equipment manufacturers.
  • Incompatible wireless standards
  • Standards debates market fragmentation
    Indecision with standard policies.
  • A lack of available 3G spectrum
  • Licensing chaos the FCCs cellular licensing
    begins

The Development of mobile market in Japan
10
Noticeable Trends in Japans Cellular Market
  • Mobile networks carry more data traffic than
    voice traffic
  • Japan's 3G networks already account for all net
    new service subscriptions
  • Japan 3G subscribers 39.429m
  • 3G user percentage in total mobile
    subscribers is about 40 (Updated 11/30/2005)
  • More than one thousand WiFi public access points
    are already available around Japan and dual
    WiFi-cellular devices are already available.

11
What leads to Japans 3G success?
  • 3 factors of 3G success in Japan
  • Network
  • Good Cellular Network Coverage
  • Handsets
  • Wide Variety of Advanced Cell Phones and
    Appealing Contents
  • Economical prices of cell phones, encourage
    yearly upgrades.
  • --cell phone has become a fashion item,
    rather than a practical technology.
  • services
  • No charge for incoming calls, which helps lower
    basic voice telephony rates and drives users to
    spend this part of expenditure on more data
    services.
  • iMODE platform, which settled the ground for 3G
    data service and has put in data connectivity
    throughout Japan. I-Mode service can be viewed as
    an prime transition from 2G to 3G service, which
    successfully establish the habit of using cell
    phones to transmit data in Japan.

12
What is iMode?
  • i-Mode is a mobile internet business system with
    45 million users and more than 3000 participating
    companies performing a great variety of mobile
    business transactions, from email, booking rail
    and air-tickets to games. I-Mode service
    includes both a proprietary "walled-garden"-type
    official menu, mainly used for selling content
    and games and providing information services, as
    well as a completely open free access to the
    internet.
  • In Japan i-Mode relies of DoCoMo¹s 2G and 3G
    packet switched DoPa data networks. Business
    transactions over i-mode are many billion
    dollards per year, and i-Mode has become an
    important part of Japan¹s social and commercial
    infrastructure. i-Mode and competing systems have
    been completely integrated into the daily life of
    most Japanese people. (Eurotechnology Japan K.K.,
    What is i-mode? / Encyclopedia-type definition of
    i-Mode).

13
Existing Problems of Cellular Industry in U.S.
  • Insufficient network coverage
  • better coverage to metropolitan cities, the
    coverage in rural area is sparse and often out of
    service.
  • Offer only the basic features, such as voice
    calling and text-messaging, to their subscribers.
  • The failure for WAP (Wireless Application
    Protocol) to receive the universal support it
    expected, in part due to its lack of an always
    on feature.
  • high service costs
  • Lack of variety and matching hand-held devices
  • Lack of usable (appealing) content

17
Merger of Cellular Operators in
U.S.Intercarrier Compensation on Network
Coverage
  • In 2004, Cingular Wireless acquisition of ATT
    Wireless and the merger between Sprint and Nextel
    have concentrated the wireless market into the
    hands of three players
  • Cingular Wireless, Verizon Wireless, and
    Sprint Nextel
  • Contributions
  • Cost-saving on spectrum/license/infrastructure
    fees
  • Rural cellular networks establishment

18
What can U.S. learn from Japans 3G experience?
  • Enhance Network Coverage
  • Selling services rather than selling technology.
    (Steinbock, 2003, 216)
  • No charge for incoming calls
  • Wide Variety of Advanced Cell Phones and
    Appealing Contents
  • Economical prices of cell phones
