South Korea's research team has successfully developed a next-generation mobile communication system that can transmit a variety of information in a 120-kilometer high-speed movement, said 30th (ETRI). 3GPP (3Generation Partnership Project) long-term Evolution plan (LTE Long term Evolution) "and was the first to complete auditions worldwide.

Yonhap noted that the "3GPP LTE", developed by Samsung Electronics and KTF, has made a significant technical progress over the third generation wireless communication system WCDMA (wideband Code Division multiple Access) Multimedia services can be provided during high-speed movement, so it is evaluated as a 3.9-generation technology near the fourth generation technology.

The 3GPP LTE system developed at an hourly rate of less than 3 km, the transmission speed can reach 100Mbps, while the speed of more than 120 kilometers will transfer faster than 30Mbps. This is better than the high-speed downlink packet access technology, which is called the 3.5 generation Mobile communication mode (HSDPA High Speed downlink Packet Access has a data transfer rate of more than 7 times times faster.

On the day of the audition, Etri in a laboratory environment, at a speed of 120 kilometers per hour of the case, the speed of 65,000 to 105,000 trillion and the base station terminal between the data transfer operation.

In particular, the launch of the 3GPP LTE is the "third generation mobile communication system network structure (3GPP lte/sae) Modem" Specifications to the application service specifications of the integrated system technology. South Korea, through this technology than in Europe and other developed countries, early six months to seize the future of the fourth generation Technology (imt-advanced) core basic technology.
