3G Technology Overview
[attachment=44629]
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.
There are some other players too:
· 3G America (formerly, Universal Wireless Communications Consortium or UWCC) (http://www.3gamerica)
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
"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.
