A wireless mobile radio technology designed to succeed 3G WCDMA/HSDPA/HSUPA (and also CDMA) technology
Its primary feature for users is faster data, although it also improves the efficiency and capacity of wireless networks.
Although "LTE" is not the name of the standard itself, it is often used that way. The actual standard is called 3GPP Release 8 (or greater).
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.
The first version of LTE to be widely deployed was LTE Category 3. It supports download data rates of up to 100 Mbps.
Newer versions include Category 4 and higher, which add new technologies such as Carrier Aggregation to boost data speeds to 150 Mbps and higher. These newer iterations of LTE include other new technologies to make networks more efficient and robust, as well as support for denser networks to cover denser populations in urban areas.
