CDMA2000(IMT MC)

Radio transmission technology for the evolutionof narrowband cdmaOne/ IS-95 to 3G byadding up multiple carriers

3G??? Also known as IMT-CDMA Multi-Carrier (1X/3X). Backward compatible with IS-95 (cdmaOne), a

principle reason for its likely adoption inexisting IS-95 networks.

CDMA2000-1X

First commercially available 3G (IMT- 2000)standard

supports medium data rate (MD R) of 153.6

kbps toward 307 kbps peak data rate 1x (1.25 MHz bandwidth carrier) Doubles capacity for voice communications Backwards compatible with cdmaOne (IS-95) Also known as IMT-CDMA Multi-Carrier (1X/3X)

CDMA2000-1X( CO NTD.)

Improved on the battery life Introduction of Radio Configurations

(Transmission formats characterized byphysical layer parameters such as data rates,modulation characteristics, and spreading rate.) RCs help in providing for additional datarates.

CDMA2000-1X EV-D O

Supporting data rates of up to 2.4 Mbps Having no backward-compatibility with CDMA

2000 Providing Adaptive modulation and coding Providing Macro diversity via radio selection

Using a multi-level modulation format ( QP SK, 8-PSK, 16- QAM)

CDMA2000-1X EV-DV

Supports both voice and data services over astandard (1X) CDMA channel

Provides up to twice the capacity of earlierCDMA2000 systems

Accommodate the continuing growth of voiceservices as well as new wireless Internet

services Support 3.1 Mbps peak data rate per sector Support real-time & non real-time data services

Operator has the option of overlaying 1xEV-DV on the same carrier as supports

IS-95A/ B or 1X. This allows the operator to control the migration and customize spectrum usage.

CDMA2000-3X

Multicarrier techniques are used for increasedbandwidth

Three adjacent 1.25MHz radio channels areused together

Throughput in excess of 2Mbps possible 3 non adjacent channels=no new RF h/w

1XEV DO-NETWO RK ARCHITECTURE

EV-DO implementation is the same as 1X architecture system butwithout using Mobile Switching Center (MSC).

When users transmit data, data packets will be sent from wirelessdevice through air interface towards BTS. Data packets thenforwarded to BSC. BSC will forward data to PDSN.

For receiving data, data packets for users will be prepared in theproviders I P network then forwarded by PDSN to BSC

Cell site, towers, antenna share carrier frequency between 1x and

1xEV-DO. 1x and 1xEV-DO uses the same PDSN in the network.
