Long-Term Evolution

A wireless mobile radio technology designed to succeed 3G WCDMA/HSDPA/HSUPA (and also CDMA) technology.

Although "LTE" is not the name of the standard itself, it is often used that way. The actual standard is called 3GPP Release 8.

LTE is considered by many to be a "4G" technology, both because it is faster than 3G, and because it uses an "all-IP" architecture where everything (including voice) is handled as data, similar to the Internet.
