3. 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 First Generation AMPS + Other Analog - Mostly Voice Common Technology North America, AMPS 70 + Countries Japan - Total Access Communications - TACS Nordic - NMT - Nordic Mobile Telephone Europe Initial Systems - Roaming Difficulties Second Generation - Digital - Mostly Voice - Three Major Standards TIA ANSI 41 Based Systems TDMA, CDMA GSM - Europe Common System Replaced Analog PDC- Personal Digital Communications??? - Japan 2G+ = Addition of Technologies that will make wireless more suited for data flow. GPRS - General Packet Radio Service - mobile packet technology - 115 kbps - Early 2000. EDGE Enhanced Data rates for GSM Evolution - 128 kbps wide area 384 kbps in local area - early 2000. Bluetooth - short range radio system to transmit mobile data between mobile station and other digital devices. Third Generation - Digital + Significant Data, Video +++ Universal, Seamless Global System, Circuit and Packet Modes Full Realization May be 4th Generation All Major Vendors Involved - Different Approaches - More Later Major International Effort in Standards Through International Telecommunications Union (ITU): IMT - 2000 First Generation AMPS + Other Analog - Mostly Voice Common Technology North America, AMPS 70 + Countries Japan - Total Access Communications - TACS Nordic - NMT - Nordic Mobile Telephone Europe Initial Systems - Roaming Difficulties Second Generation - Digital - Mostly Voice - Three Major Standards TIA ANSI 41 Based Systems TDMA, CDMA GSM - Europe Common System Replaced Analog PDC- Personal Digital Communications??? - Japan 2G+ = Addition of Technologies that will make wireless more suited for data flow.

4. 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) 2G = Circuit Switched, Limited Bandwidth Separate Voice and Data Nets 3G = More Capacity Improved Vocoder (2G Also) Packetized = Efficient Integrated Net Standard Interfaces Higher Data Rate Transport Separate from Net Intelligence ====== Higher Capacity, More Services Lower Cost Per Sub and Per Service Factors driving wireless data applications into traditional voice-based wireless communications networks. Internet includes email, web browsing, corporate LAN access Additional non voice services for incremental revenue improved technology higher data rates, user friendly data enabled handsets, better coordination of vendors network and subscriber handset development programs.
