Seminar on 3G Wireless
[attachment=29141]
What is 3G?
First Generation Wireless : Analog
Second Generation Wireless (2G): Digital
Second Generation Wireless + (2G+): More Data
Third Generation Wireless (3G):
Universal Global Wireless Voice and Data System
Worldwide Effort Toward 3G
International Standard Underway: IMT-2000
Comparison 2G vs. 3G Networks
Today’s Networks (“2G Networks”):
Circuit-switched Data or Limited Bandwidth Packet-switched Data
Separate Networks for Voice and Data
Third Generation Networks (“3G Networks”)
Improved Capacity on Radio Interface (Increased Number of Users Per Cell)
Improved Vocoder Technology (Lower Bit Rate Voice)
Packetized Voice and Data (More Efficient Use of Transport)
Single, Integrated Network (More Efficient Staffing for Provisioning and Maintenance)
Standard Interfaces (Takes Advantage of Competitive Hardware Pricing)
Capable of Supporting Higher Rate Data and Integrated Voice and Data Services (New Revenue Opportunities)
Transport (E.G., Routers, Switches, and Gateways) Are Separated From Service and Call Control Intelligence (Lower Cost of Transport Elements, Open Interfaces for Service Development Encourage Rich Service Offerings)
The 3G Vision
Global Seamless Roaming
Common Worldwide Spectrum
Multiple Radio Environments
Wide Range of Services -Voice & Data Equally
Flexible, Spectrum Efficient Technologies
Wireless - Wireline Integration
Enhanced Security and Performance
Wireline Services and Quality Levels
Rapid Introduction of New Technology
3G Vision - Characteristics
Variety of Multi-Mode Terminal Types
Common Radio Interfaces
Open Architecture
Modular Design
3G Stand Alone or Integrated to Existing Networks
Framework for Mobility Services from Fixed Network
Service Provision by Multiple Networks
3G Vision - Interoperability
Legacy Systems
Interoperability Between Different Standards (E.G., ANSI-41, GSM Based Networks)
How Achieve Interoperability?
Goal: One Global Standard or “Family of Standards” World Wide: IMT - 2000
Phased Implementation
3G Business Issues
Market:
Rapid Growth Continues
Competition Increases
Transition to Data and Multi-Media
What’s At Stake:
Vendor Sales With New Technologies
Vendor Health / Survival
Continued Robust Market Growth / Carrier Health
Major Trade Offs
Level of Backward Compatibility
Handset, Network or Combined Interoperability Solution
Speed of Implementation
Segmenting the Market - When 3G?
Asian Pacific Rim Market (2000-2001)
Transition Motivation: Need to Increase Voice Capacity, 2G+ Sufficient for Some?
European Market (2001-2003)
Transition Motivation: Need to Develop and Provide Value Added Services
GSM Built Out
U.S. Market (2003-2005)
Transition Motivation: Need a Reason for Transition From 2G to 3G
2G Network Being Built Out
3G Standards
International Mobile Telecommunication Standards For the 21st Century: IMT - 2000
ITU Radio and Network Standards
Phased Implementation
Allocated Spectrum 1.8 - 2.2 Ghz
Family of Systems / Standards
Support Circuit Data, Digital Voice and Packet Services
Minimum Speeds:
144 kbit - Vehicle, 384 kbit - Pedestrian, 2 Mbps - Fixed
