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.

• 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 encompassesRadio, 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 someoverlap 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. CDMA20003. TD-SCDMA (Chinese system)

4. TD-CDMA (North American System by a relatively small company

3 Evolution and Revolution to 3G


(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)
