SYNOPSIS

Why 3G? Types of internet connectivity 3G data rate 3G services in Asia Evolution of Mobile Systems to 3G 3G standards W-CDMA Impact on existing network CDMA2000 evolution to 3G 3.5G 3G applications

3 G

3G is the next generation of mobile communications systems.

It enhances the services such as multimedia, high speed mobile broadband, internet access with the ability to view video footage on your mobile handset.

With a 3G phone and access to the 3G network you can make video calls, watch live TV, access the high speed internet, receive emails and download music tracks, as well as the usual voice call and messaging services found on a mobile phone, like person to person video, live streaming, downloadable video of entertainment, news, current affairs and sport content and video messaging

3G CAPABILITIES

High speed data transmission

Improved voice quality

Greater capacity

Multiple simultaneous services

3G STANDARDS

3G Standard is created by ITU-T and is called as IMT-2000.

The aim of IMT-2000 is to harmonize worldwide 3G systems to provide Global Roaming.

W-CDMA makes possible a world of mobile multimedia

IMPACT ON EXISTING NETWORK

Yes, New W-CDMA handsets will work on W-CDMA at 2Mbps, EDGE n/w at 384 Kbps, GPRS n/w at 144 Kbps. GSM n/w at 9.9 Kbps. Older handsets will not work in W-CDMA.

Yes

Requires completely new base stations

FDD5MHzW-CDMA

Yes, New handsets work on EDGE n/w at 384Kbps, GPRS n/w at 144Kbps, and GSM n/w at 9.6 Kbps with tri-mode phones. GSM and GPRS-only phones will not work in EDGE n/w.

No

Requires new transceivers at base station. Also, software upgrade to the BSC & BTS

FDD200KHzEDGE

Yes, New GPRS handsets work on GPRS n/w at 171.2Kbps, 9.6 Kbps on GSM n/w with dual mode phones. GSM only phones will not work in GPRS n/w.

No

Requires new packet overlay including routers and gateways

FDD200KHzGPRS

Yes, New HSCSD handsets provide 57.6Kbps on HSCSD n/w and 9.6 Kbps on GSM n/w with dual mode phones. GSM only phones will not work in HSCSD N/w.

CDMA 1xEV-DV

Backward compatible with CDMA 2000. EV-DV can be easily extended to operate in 3x mode

under the framework of current system. Forward peak data rate : 3.072 Mbps. Reverse peak data rate: 451.2 kbps. Addition of three new channels to f/w link and reverse

link for packet data operation and its support. Adaptive modulation and coding : QPSK, 8- PSK, 16-

QAM Variable frame duration Mobile station can select one of N base stations. DTX transmission supported for saving battery life.

3.5G

3.5G or HSDPA (High Speed Downlink Packet Access) is an enhanced version and the next intermediate generation of 3G UMTS.

It comprises the technologies that improve the Air Interface and increase the spectral efficiency, to support data rates of the order of 30 Mbps.

It introduces many new features that will enhance the UMTS technology in future.

These include: Adaptive Modulation and Coding Fast Scheduling Backward compatibility with 3G Enhanced Air interface
