Long Term Evolution (LTE) Technology

Long Term Evolution (LTE) technology, commonly known as 4G, is a cellular network resulting from the development of the previous technology, 3G. This network is very useful for broadband technology, and of course long-distance communication also becomes easier.

Long Term Evolution (LTE) technology is a development of the 3GPP standard that was developed in stages, known as 3GPP releases. Its development is as follows:

1. 3GPP Release 99 is the first release of the UMTS / WCDMA standard, and this work was continued with the introduction of HSDPA and HSUPA to form HSPA.
2. 3GPP Release 4: in this version there were improvements to the core network. The concept of an all-IP network was introduced in this release.
3. 3GPP Release 5: the changes occurred on the UMTS air interface side.
4. 3GPP Release 6: there were several additional features on the uplink side known as HSUPA (High Speed Uplink Packet Data). Subsequently, the term HSPA (High Speed Packet Access) is usually used to describe release 6 technology.
5. 3GPP Release 7, often called HSPA+, is a development of HSPA technology. It began from the development of the LTE system, which is able to provide more capable bandwidth and system capacity.
6. 3GPP Release 8 is a further development to improve system efficiency and data rate by providing the MIMO antenna concept with 64 QAM modulation, dual cell operation, and better battery and power improvements.
