This book explains how the 1x
Evolution (1XEV) data only (EVDO) system modifies (optimizes) the 1.25 MHz
IS-95 radio channel structure to provide high-speed data services (up to 2.4
Mbps) to wireless customers. The EVDO system allows cellular service
providers carriers to use one of more IS-95 CDMA radio channels (with
changes) to provide broadband high-speed data services to their customers.
The EVDO is an "always-on" system that allows users to browse the
Internet without complicated dialup connections.
