CDMA vs. OFDMA
CDMA and OFDMA are different technologies with different CDMA and OFDMA are different technologies with different capabilities capabilities
CDMA2000 1X and EVCDMA2000 1X and EV--DO are more efficient in bandwidths up to 5 DO are more efficient in bandwidths up to 5 MHzMHzOFDMAOFDMA--based solutions offers a simpler implementation in based solutions offers a simpler implementation in bandwidths greater than 10 MHzbandwidths greater than 10 MHz

Evolution Scenario 1
1X 1X 1XEV-DO
EV-DO
New entrants of developed countries normally have limited CDMA spectrum and Voice service market shares, they can leverage capacity enhancements to 1X technology to empty more carriers for EV-DO
Carriers with limited bandwidth
Evolution Scenario 1 cont.
Current In the future
New SpectrumCDMA
Carriers with maximum 2.5MHz bandwidth for EV-DO
Evolution Scenario 2
Current In the future
New SpectrumCDMA
Carriers with maximum 5MHz bandwidth for EV-DO
Evolution Scenario 3
Current In the future
New SpectrumCDMA LTE
Carriers with access to more than 10MHz of clear and unused spectrum
