EVDO Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (Ev-DO, EV,
EVDO, etc.).
A telecommunications standard for the wireless transmission of data through radio
signals, typically for broadband Internet access. It uses multiplexing techniques
including code division multiple access (CDMA) as well as time division
multiplexing (TDM) to maximize both individual users' throughput and the overall
system throughput.

This extends and improves the performance of existing 3rd generation mobile
telecommunication networks utilizing the WCDMA protocols.
HSPA+ Also called evolved HSPA
This allows bit-rates to reach as high as 168 Mbit/s in the downlink and 22 Mbit/s in
the uplink. An improved 3GPP standard.
IC Industry Canada
