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.

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.

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.
