Since the world's first 5G pre-commercial service was demonstrated at the 2018 Pyeongchang Winter Olympics in Korea, communication technologies have been established with the likes of intelligence and information technologies as the basis of the Fourth Industrial Revolution. 5G was designed not only to provide an improved experience for existing smartphone users and IoT devices, but also to meet the diverse requirements of mobile communications services in future applications targeted for vehicles and factory automation.
5G acts as a mobile communications platform on which extensions targeted for different vertical services can be optimized individually.
These characteristics are the reasons 5G is referred to as the connectivity platform of the Fourth Industrial Revolution. To this end, Samsung will emphasize tireless technological innovation and research toward next-generation communications as we work to prepare our ascent as the world’s premier telecommunications company through precedent research for greater 5G competitiveness, the Beyond 5G to overcome the initial 5G Pain Point, and 6G in preparation for the next decade.
With next-generation communications, we aim to contribute towards the rise of Samsung as the premier telecommunications company in the world through various researches in core telecommunications technologies, distinct technologies in products and services, and MEC-based new business solutions. We are also working to secure core technologies in AI, as its importance has continued to grow in the field of telecommunication, and use these for automation and intelligence in 5G devices.
Samsung Research is currently pursuing core technologies and developments in vRAN with the goal of greater competitiveness in the network business and 5G and is developing the MEC platform that can realize innovative services based on 5G ultra low latency.
We are also seeking to build greater competence in standardization to provide greater support toward the 5G business to complete the 5G Vertical services promptly.
Samsung Research will commit to resolve the initial pain points identified during the commercialization of 5G services and continue the efforts in technological development to acquire core technologies for the enhancement of services under the Beyond 5G project, thereby maintaining our means to strengthen our leadership in the 5G business. Finally, our precedent research in 6G will help us create the future drivers for our telecommunication business as core technologies that will bring about great changes across the industry board in the next decade.
In an era where 4G LTE is already an integral necessity in our lives, what is 5G? How will it change our lives? What can we expect from it?
Since the days of analog technology in the late 1970s, commercial mobile communication has been continuously evolving with each new generation enabling new services. The LTE technology used in many of our smartphones for voice/video calls or video streaming is 4G. And 5G is the latest generation which was recently developed that will enable a whole new suite of mobile services. What sets each generation apart from each other are the technical breakthroughs that make such new services a reality..
With every new generation, technical breakthroughs are made to enable mobile communications over new frequency bands, with faster data rates, and offering new services. These technical breakthroughs are realized in the form of ‘standards’ which detail the radio access and network technologies to achieve the envisioned requirements of each generation.
In the early 2010s, when 4G LTE standards were just hot off the press and commercial 4G services were about to take off, there was already a forecast among the technical community that by the 2020s, this technology would no longer be able to accommodate the exploding demand for wireless traffic. A new generation of mobile communications that can overcome the limits of 4G would be needed. Many organizations in academia and industry responded by initiating research on next-generation
breakthrough technologies with Samsung Electronics leading the pack with its own 5G research initiative in 2011.
In line with such research movement across the globe, ITU (International Telecommunication Union) held a World Radio communication Assembly in October 2015 where they designated the official name of 5G as 'International Mobile Telecommunication (IMT)-2020' and published the technical vision of 5G.
According to ITU's definition, 5G is a mobile communications technology that can support a peak download speed of up to 20Gbps and a user-experienced download speed of at least 100Mbps. Also, it should be able to provide IoT services to 1 million devices within a 1km2 area and enable a seamless mobile experience onboard a train traveling at 500km/h. To accommodate these requirements, ITU also assigned a new spectrum range for 5G which is broader and higher than that defined for 4G. The spectrum range includes not only low frequency bands below 6GHz (including 3.5GHz), which are similar to the conventional 4G spectrum, but also the ultra-high frequency millimeter wave (mmWave) bands such as 28GHz and 39GHz which were never previously used for the purpose of mobile communications. 5G mobile communication has three key components: (1) enhanced Mobile Broadband (eMBB); (2) Ultra Reliable & Low Latency Communications (URLLC); and (3) Massive Machine-Type Communications (mMTC).
Some of the new applications that are expected to be serviced over 5G are UHD-based AR/VR and holograms which require massive amount of data to be transferred from one point to another. Compared to 4G, 5G utilizes wider bandwidth as well as advanced transmissions using more antennas to achieve a data rate that is at least 100Mbps and up to 20Gbps for a user. For example, downloading a single 15GB movie takes at least four minutes for 4G LTE (at the peak data rate of 500Mbps), but only six seconds for 5G at the peak data rate of 20Gbps.
Another aspect in which 5G is technically superior to 4G is its ability to reliably deliver data with minimal latency. Latency, which typically is in the order of tens of milliseconds (1ms is 1/1000th of a second) for 4G can be reduced to about 1ms for 5G. For example, in a 4G network, when an obstacle appears in front of a self-driving car moving at 100km/h, a stop signal can be received only after the car has driven more than 1m. The same distance can be reduced to 2.8cm in a 5G network, drastically reducing the risk of vehicular accidents.
Besides the big jump in data rates and latency, 5G is expected to play a critical role as a platform for providing connectivity to various forms of IoT devices in homes and industries. 5G aims to enable connections for 1 million devices within an area of 1km2. Such connectivity on a massive scale is essential in order to accommodate an exponentially increasing number of IoT devices such as smart devices and sensors.
