Indonesia Will Feel the Speed of the 4G Network

4G is an abbreviation of the term in English: fourth-generation technology. This term is generally us in reference to the fourth generation standard of cellular telephone technology. 4G is a development of 3G and 2G technology. The 4G system provides an ultra wide band network for various electronic equipment, for example smartphones and laptops using a usb modem.

3GPP Long Term Evolution or commonly abbreviat as LTE is a high-level wireless data access communication standard bas on GSM/EDGE and UMTS/HSPA networks. Its network interface is incompatible with 2G and 3G networks and so must operate over a separate wireless spectrum. This technology is capable of downloading up to 300mbps and uploading rates of 75mbps.

The LTE-bas4G cellular service network will not only

Operate at 900 MHz, but also in two other Colombia Mobile Database spectrums. Including the frequency domain which is currently still the ‘home’ for 3G, this was reveal by the Minister of Communication and Informatics Rudiantara. 3GPP Long Term Evolution (LTE) and market under the name 4G LTE is a wireless communication standard bas on GSM/EDGE and UMTS/HSDPA networks for high-spe data access using cellular phones and other mobile devices. LTE is tout as the fastest wireless network today, as a successor to the 3G network. LTE even claim to be the fastest growing wireless network.

The LTE technology that has been test by several operators in Indonesia is not a true 4G technology. The technology that has been test in Indonesia is LTE release – 8 which only meets 3GPP specifications but does not yet meet IMT-advanc specifications.

The 3 operators that have been recordas testing LTE technology are Telkomsel, Indosat and XL Axiata. Even so, LTE can be brought down to the market in about two more years. Given that the government is currently concentrating on WiMAX technology that was recently adopt by Indonesia.

On November 14, 2013, telecommunications company Internux launch the first 4G LTE service in Indonesia, namely Bolt Super 4G LTE. Bolt offers data access speeds of up to 72 Mbps, faster than Smartfren’s EVDO Rev.B technology which offers data access speeds of up to 14.7 Mbps

LTE technology and its services

Cell Phone Number List

LTE technology theoretically offers downlink speeds of up to 300 Mbps and 75 Mbps uplink.
LTE uses Orthogonal Frequency Division Mutiplexing (OFDM). Which DJ USA transmits data over many radio spectrum operators, each of which is 180 KHz. OFDM transmits by dividing the data stream into many slower streams which are then transmitt simultaneously. Using OFDM minimizes the possibility of multi path effects.
Increasing the overall transmission speed, the transmission channel us by LTE is enlargby increasing. The quantity of the number of radio spectrum operators without changing the parameters of the radio spectrum channel itself. LTE must be able to adapt according to the amount of available bandwidth.
LTE adopts an all-IP approach. Using this all-IP network architecture simplifies the design and implementation of the LTE interface, radio network and core network, thereby enabling the wireless industry to operate like a fix-line network.
To be universal, mobile devices bason LTE must also be able to support GSM, GPRS, EDGE and UMTS. When viewfrom the network side, interfaces and protocols are placin places that allow data transfer to occur as smoothly as possible if the user moves to an area that has a different interface technology.
