There are two candidates for 4G standards are commercialized in the world which is the standard WiMAX (South Korea since 2006) and the standard Long Term Evolution (LTE) (Sweden since 2009).
In Indonesia, WiMAX was first launched by PT. Firstmedia with trademark Sitra WiMAX since June 2010. Then LTE technology was first launched by PT. Internux with trademark Super Bolt 4G LTE since 14 November 2013.
As for LTE, 3GPP Long Term Evolution or commonly abbreviated as LTE is a wireless communications standard high-level data access based on GSM / EDGE and UMTS / HSPA. Network interface does not match with 2G and 3G networks, so it must be operated through a separate wireless spectrum. This technology is able to download up to the level of 300Mbps and 75Mbps upload. LTE service was first adopted by mobile operators TeliaSonera in Stockholm and Oslo on 14 December 2009.
3GPP Long Term Evolution (LTE) and is marketed as 4G LTE is a wireless communication standard based on GSM / EDGE and UMTS / HSDPA for high speed data aksess using a cell phone like any other mobile device. LTE is touted as the fastest wireless networks today, as the successor to the 3G network. LTE wireless network even claimed to be the fastest growing.
LTE is a technology that was asked to replace UMTS / HSDPA. LTE is expected to be a global standardization of mobile phone first.
Although marketed as 4G technology, LTE is marketed now can not be called 4G technology entirely. LTE in 3GPP specified in Release 8 and 9 do not meet the ITU-R standardization organizations. LTE Advanced technology that will certainly meet the requirements to be called a 4G technology.
