Narrow code division multiple access (N-CDMA)

Narrow band

3G -- IMT-2000 (UMTS)

Features: Digital signal Code division multiple access (CDMA)

Broadband

MOBILE GENERATION FROM 1G TO 3G

WHAT IS 3G ALL ABOUT?

Technology?Individual new services?

3G is about improving the end user experience

Doing things: BETTER FASTER NEW

3G VISION

Same set of services

realize global roaming

single network architecture

One World, One Vision, One Network

WCDMA ~ WHAT ?

Wideband Code Division multiple Access Or

UMTS-FDD / UTRA-FDDOr

IMT-2000 CDMA Direct Spread

An air interface standard found in 3G mobile telecommunications networks.

DATA SERVICES OVER WIRELESS

WCDMA BENEFITS

Support for higher bit rates. BW on demand Asymmetric Data Rates Higher spectrum efficiency. Improved Trunking efficiency.

Higher QoS.

3G LONG TERM EVOLUTION

WCDMA(UMTS)

HSPA

HSDPA/HSUPA

HSPA+ LTE

MAX DOWNLINK SPEED (bps)

384K 14m 28m 100m

MAX UPLINK SPEED (bps)

128K 5.7m 11m 50m

3G V/S 4G

1.Data Throughput:

2. Peak Upload Rate:

3. Peak Download Rate:

4. Services And Applications

5. Frequency Band:

Up to 3.1Mbps with an average speed range between 0.5 to 1.5 Mbps

5 Mbps

100 Mbps

CDMA 2000, UMTS, EDGE etc

1.8 – 2.5GHz

Practically speaking, 2 to 12 Mbps but estimated at a range of 100 to 300 Mbps.

500 Mbps

1 Gbps

LTE-Advance

2 – 8GHz

2G,3G,4G……??????????

2G and 3G networks designed-voice communications rather than data

4G is designed especially for data transmission rather than voice
