SKT "5G Make a multinational coalition to lead the global standard" proposal

And [South Korea ohahreum financial newspaper reporter] SK Telecom is leading the global standardization 5G, take the lead in commercializing the world's first 5G.

SK Telecom ∙ AT & T ∙ NTT DOCOMO ∙ Vodafone ∙ Ericsson ∙ Qualcomm, including six global leader in ICT companies have jointly proposed to the 3GPP standard 5G network structure, accelerate innovation and early commercialization work for 5G.

Since Deutsche Telekom ∙ British Telecom ∙ Intel ∙ KT ∙ LGU +, etc. The participating companies has expanded more than 20 pieces. The 5G pace of the global ICT companies are faster and for early commercialization.

Global ICT Key, including SK Telecom companies have asked for 'NSA (Non Standalone)' standard that combines the 5G and LTE networks for 5G early commercialization and 5G-based range of services developed to promote such a 3GPP have it completed by December this year .

'NSA' is entered into the radio base station 5G 5G and the LTE network, such as connecting to wired networks to LTE technology to utilize as a single network, it has the advantage of using existing LTE network to 5G commercialization.

When you finish the NSA 3GPP standard later this year, ICT companies are expected to be ahead of the commercialization of 5G when it is expected to start in early 2020 based on the 5G infrastructure and terminal development this year.

5G key driver for the car industry of 4 to early commercialization of core technologies that are difficult Gigabit speed time due to the development and pre-emptive, but a certain consensus standards for global ICT companies.

Mobile communication standardization organization 3GPP is a collaboration plan to finish the second connection-based ultra-low latency ∙ Phase 2 standard, and up to 12 March 2019 to complete the first phase standardization work until next June.

In particular, SK Telecom plans to more concrete proposals for early commercialization of 5G in 3GPP RAN Plenary Meeting to be held on March 9 Croatia coming. SK Telecom is expected to announce AT & T, Ericsson, along with Qualcomm △ 5G 5G standardization roadmap △ including new standardized technologies.

SK Telecom has 26 days to attend the NGMN (Next Generation Mobile Network, a next-generation mobile network association) board meetings held in Barcelona, ​​offers a slice of the network interlock technology collaboration between providers. There between providers that support the efficient operation of the network through a virtual network linked slice technology is attracting attention as a key technology for 5G evolution, it is expected to be finalized in research of NGMN.

In addition, SK Telecom is a global association of TIP (Telecom Infra Project) through the evolution of next-generation base stations 5G direction of the proposed 'open base station architecture white paper was published in the, open standard for the interface of the base station announced. An open base station is to work together ∙ implement other functions in the equipment of one base station, through which operators can develop a base station for the service required by the high-speed ∙ 5G such ultra-low latency.

SK Telecom has led to the transfer speed in the high speed Giga driving environment, the world's first 5G international roaming, and handover (Handover) that crosses the LTE 5G 5G and core technology development and standardization work at the same time.

Bakjinhyo SK Telecom Network Technical Director "led 5G standardization, will stand the forefront of the world's first 5G commercialization through key technology development," he said, "In the 5G Conference to be held 27 days to introduce 5G core technology of SK Telecom and the 5G commercialization "I said it would present a roadmap.

SKT, LTE-A technology professionals sangyongmang test success

[Korea ohahreum financial newspaper reporter] 4G also opens the era of high-definition HD-quality movie (1.7GB) can download and view in 15 seconds.

SK Telecom has succeeded the last stage of LTE-A Pro (LTE-Advanced Pro) technology in LTE evolution to the test said sangyongmang 27.

SK Telecom is the MWC this three-band CA Technology CA Technology apply △ 5 △ 4x4 multi-band antenna with Samsung Electronics in 2017, Ericsson will jointly demonstrate the △ 1Gbps each unlicensed frequency band aggregation technology.

First, SK Telecom has succeeded in five frequency bands to tie the SEC and demonstrating the world's first 5-band CA (frequency aggregation) technology used in frequency as one sangyongmang.

The standardized by the 3GPP standard CA CA is now 5-band technology with frequency bands up to five LTE is the best technology. There are domestic mobile operators are SK Telecom, among the only five have a five-band frequency band it is possible to provide CA services.

In addition, SK Telecom and Samsung Electronics has implemented a download speed of up to 900Mbps in sangyongmang combines 4x4 multiple-antenna technology with three-band CA technology tie the three frequency bands.

SK Telecom has introduced LTE service speed of up to 500Mbps to apply the 256 kwam (QAM) technology since last June. Since improves the download speed almost doubled in just one year.

4x4 multi-antenna (MIMO) technique is doubled compared to existing allow for increasing the data transmission rate by utilizing the four antennas for data transmission and reception at the same time is described. The current data transmission and reception has gotta a 2x2 multi-antenna technology to utilize two antennas, each application.

SK Telecom plans to apply a 4x4 multiple antennas in commercial service in the first half of this year. When this technique is applied using SK Telecom's LTE customers will be able to view and download movies in HD quality on the go for 15 seconds.

Meanwhile, SK Telecom is exempt frequency bands to tie the aggregate technical and Ericsson Mobile Communications LTE frequency with LTE frequencies for Wi-Fi signals transmitted to: the success was also demonstrated by the speed (LAA Licensed Assisted Access) 1Gbps.

The demonstration in the LTE frequency band strapped to 20MHz and 60MHz frequency band for Wi-Fi, applying a 4x4 multiple-antenna technology in the LTE frequency band has achieved a maximum 1Gbps speed.

LTE-A technology professionals such as frequency aggregation (CA) · 4x4 multiple antennas, unlicensed frequency band aggregation technology is LTE technology specifications is developed prior to the final 5G mobile communications. SK Telecom explained that before the era 5G LTE-A technology commercialization professionals ultra-high definition (UHD) video, virtual reality (VR) and ultra realistic to expect the diffusion-type multimedia services.

SK Telecom bakjinhyo network technology director, said, "SK Telecom will continue to domestic subscribers, as well as 5G continues to innovate in LTE to experience a world-class mobile communication services."

Samsung Network Division rate of Strategic Marketing said, "Through LTE-A professional technology demonstration of this SK Telecom confirmed not far from the numbers was 1Gbps communication services commercialization of dream notes on LTE," said "technology to the final stage of the LTE technology leading the development and said we will set the stage for moving on to 5G age. "

Ericsson're in the buffer Naveen (Per Narvinger) Network Systems Executive Vice President, "This unlicensed frequency aggregation technology demonstration has been applying this technology to eliminate interference between LTE frequency and Wi-Fi frequency," he said "this LTE via ∙ Wi-Fi using both customers said it would be able to comfortably use the network.
