4What is IMT-2000?
- IMT International Mobile Telecommunications
- IMT-2000 is the 3rd generation (3G) system which
aims to unify the diverse systems we see today
into a radio infrastructure capable of offering a
wide range of services up to the rate 2000 kbps
around the year 2000 and 2000 MHz band in many
different operating environments. - Whats different about 3G?
5Characteristics of 3G

- Globalization of communication - global travelers
increasingly demand ability to be in
communication, anywhere - Increasing use of Internet usage for web browsing
and mobile multimedia and of e-mail as
communication vehicle - Growing acceptance of telecommuting/work-at-home
- Rapid increase in mobile population
- Increasing integration and overlap of work and
home - Increasing number of multiple PC and multiple TV
owners
6Characteristics of 3G

24Summary - Introduction
- 3G does not have standards-defined services and
applications - 3G will enable Wireless Service Providers to
bring new services to market - Many services will co-exist within wireless
networks and even during an end users session
bandwidth must be efficiently managed and
tailored to specific applications - Market success requires more than technology, yet
technology will be a key enabler - Wireless Network Operators will need to provide
the killer service environment - Wireless Service Providers Competitive Advantage
-- the provision of an open service environment
where content providers and applications
developers can rapidly develop, provide,
customize and deliver services to meet end users
needs - Efficiently designed services will compete with
wireline services

associated with all three 3G CDMA modes. - Supports functionality based on synchronous
operation such as location calculation, etc. - Supports seamless handoff between the harmonized
DS and MC including IS-95 for ANSI 41 and the
equivalent to this for UMTS/GSM. - Minimize the complexity of dual-mode and
muti-band terminals and equipment.

55Summary - Standardization for IMT-2000
- 3G system shall be evolved from 2G system and
different countries are standing in different
positions according to 2G systems deployed - There are multiple systems for IMT-2000 and
multiple paths to 3G it is important to choose
the best way to reach to the goal - There are many standard bodies in the world and
many companies in each standard body.
Harmonisation between these companies is very
important even though these companies are very
competitive. - Harmonisation results for IMT-2000 terrestrial
