3G is designed to provide voice and high-speed mobile data using the cellular approach already proven to work in mobile phone networks. The biggest obstacle to implementing high speed wireless networks is the lack of bandwidth, or range of usable frequencies. Just as only so many radio stations can be squeezed onto the FM dial, only so much data can be transmitted across the available bandwidth. EVDO is an advanced CDMA technology developed by Qualcomm to deal with this limitation.
