Route to 3G

l 1G: Analog

l 2G : 1st digital mobile telephony

l 2.5G: transition from 2G to 3G

l 3G standard: IMT 2000


3G Advantages

l Improved digital voice communications

l Larger Bandwidth – Higher Data rate

l Greater subscriber capacity

l Fast packet-based data services like e-mail, short message service (SMS), and Internet access at broadband speeds.

l Most carriers also expect consumers to want:

p location services

p interactive gaming

p streaming video

p home monitoring and control


3G Capabilities

l Specified data ratesp 384 kbps for motion up to 120 km/hour

p 144 kbps for high speed mobility (> 120 km/hour)

p 2 mbps for stationary devices

l Frequenciesp Uplink: 1885-2025 MHz

p Downlink: 2110-2200 MHz


UMTS / WCDMA

l WCDMA: Wideband Direct Sequence Code Division Multiple Access

l The WCDMA system uses the following frequency spectrum

- Uplink 1920 MHz ~ 1980 MHz

- Downlink 2110 MHz ~ 2170 MHz

l Channel Bandwidth: 5MHz

l Chip rate: 3.84 Mcps
