1 Major 3G Players
International Telecommunications Union (ITU) defined International Mobile Telecommunications-2000 (IMT-2000) as the
umbrella of third generation (3G) wireless (not just cellular mobile) communications technologies. This initiative envisioned
a single 3G system that integrates a variety of systems including cellular mobile, cordless phone, wireless data and LEO
satellite systems. The following table gives the current members of IMT-2000 initiative.




                        http://www.comsec.uwaterloo.ca/~flchiu/CDMA/IMT2000%20standard.pdf

•   3GPP = 3G Partnership Project (ITU’s IMT-2000 project – UMTS implementation)
    Ref: http://en.wikipedia.org/wiki/3GPP

    The 3rd Generation Partnership Project (3GPP) is a collaboration between groups of telecommunications associations, to
    make a globally applicable third generation (3G) mobile phone system specification within the scope of the International
    Mobile Telecommunications-2000 project of the International Telecommunication Union (ITU). 3GPP specifications are
    based on evolved Global System for Mobile Communications (GSM) specifications. 3GPP standardization encompasses
    Radio, Core Network and Service architecture.[1]

    The groups are the European Telecommunications Standards Institute, Association of Radio Industries and
    Businesses/Telecommunication Technology Committee (ARIB/TTC) (Japan), China Communications Standards
    Association [2], Alliance for Telecommunications Industry Solutions (North America) and Telecommunications
    Technology Association (South Korea).[1] The project was established in December 1998.

    3GPP should not be confused with 3rd Generation Partnership Project 2 (3GPP2), which specifies standards for another
    3G technology based on IS-95 (CDMA), commonly known as CDMA2000

•   3GPP2 = 3G Partnership Project 2 (ITU’s IMT-2000 project – CDMA2000 implementation)
    Ref: http://en.wikipedia.org/wiki/3rd_Generation_Partnership_Project_2

    The 3rd Generation Partnership Project 2 (3GPP2) is a collaboration between telecommunications associations to
    make a globally applicable third generation (3G) mobile phone system specification within the scope of the ITU's IMT-
    2000 project. In practice, 3GPP2 is the standardization group for CDMA2000, the set of 3G standards based on earlier
    2G CDMA technology.

    The participating associations are ARIB/TTC (Japan), China Communications Standards Association,
    Telecommunications Industry Association (North America) and Telecommunications Technology Association (South
    Korea). The agreement was established in December 1998.

    3GPP2 should not be confused with 3GPP, which specifies standards for another 3G technology known as UMTS.

There are some other players too:

•   3G America (formerly, Universal Wireless Communications Consortium or UWCC) (http://www.3gamerica.org/)

    The mission of 3G Americas is to promote and facilitate the seamless deployment throughout the Americas of GSM and
    its evolution to 3G and beyond. The organization provides a unified voice for operators, vendors and content providers
    promoting the growth and success of GSM wireless technologies via GSM, GPRS, EDGE, UMTS-HSPA and LTE.


•   Open Mobile Alliance (OMA) http://www.openmobilealliance.org/

    "The mission of the Open Mobile Alliance is to facilitate global user adoption of mobile data services by specifying
    market driven mobile service enablers that ensure service interoperability across devices, geographies, service providers,
    operators, and networks while allowing businesses to compete through innovation and differentiation."

    The OMA was created in June 2002 as an answer to the proliferation of industry forums each dealing with a few
    application protocols: the WAP Forum (focused on browsing and device provisioning protocols), the Wireless Village
    (focused on instant messaging and presence), the The SyncML Initiative (focused on data synchronization), the Location
    Interoperability Forum, the Mobile Games Interoperability Forum and the Mobile Wireless Internet Forum. Each of
    these forums had its bylaws, its decision-taking procedures, its release schedules, and in some instances there was some
    overlap in the specifications, causing duplication of work. The OMA was created to gather these initiatives under a
    single umbrella.

    Members include traditional wireless industry players such as equipment and mobile systems manufacturers (Ericsson,
    Thomson, Siemens, Nokia, Openwave, Sony Ericsson, Philips, Motorola, Samsung, Texas Instruments...) and mobile
    operators (Telefónica, Vodafone, Orange, T-Mobile...), but also software vendors (Microsoft, Sun Microsystems, IBM,
    Oracle Corporation, Symbian, Celltick, Expway, Motive, Discretix...)




2 IMT-2000 Framework for 3G Wireless Networks
The IMT-2000 framework sets the following goals for the so called 3G wireless systems.

Cellular Systems:
    • UMTS (Universal Mobile Telecommunication System) by 3GPP (3G Partnership Project): This mostly based on
         GSM protocols but radio multiple access technique is CDMA (instead of TDMA of GSM)
    • CDMA2000 by 3GPP2: This is an alternative initiative which is extending CDMAone to 3G
    • UWC-136 (Universal Wireless Communications – 136) by Universal Wireless Communication Consortium
         (UWCC): This is putting commonalities of GSM and North American TDMA (IS-136) into a new 3G system. This
         initiative keeps its TDMA multiple access technology (not going for CDMA)

Other Systems (Non-Cellular Systems):
    • DECT (Digital Enhanced Cordless Telecommunications) is, indeed, a cordless system
    • WiMax is wireless data communications system (something like WAN of Wi-Fi technology)

Future cellular systems appear to be CDMA. However, it has 4 systems, which are listed below according to apparent
dominance (most to least)
  1. W-CDMA
  2. CDMA2000
  3. TD-SCDMA (Chinese system)
  4. TD-CDMA (North American System by a relatively small company

                       (For Historical Chronology: http://www.umtsworld.com/umts/history.htm)

        o   TDMA is IS-136 (Digital AMPS) system
        o   IS-95 is cdmaOne
        o   1xRTT = Single-carrier Radio Transmission Technology
        o   HDR = Qualcomm’s patented technology (High Data Rate)
