Evolution-Data Optimized or Evolution-Data only , abbreviated as EV-DO or EVDO and often EV, is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access.
It is standardized by 3rd Generation Partnership Project 2 (3GPP2) as part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers around the world – particularly those previously employing CDMA networks.
It is also used on the Globalstar satellite phone network.
Channel Being Time Multiplexed on the forward link means that a single mobile has full use of the forward traffic channel within a particular geographic area (a sector) during a given slot of time.
The forward channel is divided into slots, each being 1.667 ms long.
These streams include the Pilot which helps the mobile find and identify the channel, the Media Access Channel (MAC ) which tells the mobiles when their data is scheduled, and the Control Channel , which contains other information that the network needs the mobiles to know
