![]() ![]() To accommodate the requirements as described above, a new spectrum range was assigned for 5G, which is broader and higher than 4G. Such connectivity on a massive scale, i.e., mMTC, is essential in order to accommodate an exponentially increasing number of IoT devices such as smart devices and sensors. ![]() 5G aims to enable connections for 1 million devices within an area of 1km2. The same distance can be reduced to 2.8 cm in a 5G network, drastically reducing the risk of vehicular accidents.īesides 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. For example, in a 4G network, when an obstacle appears in front of a self-driving car moving at 100 km/h, a stop signal can be received only after the car has driven more than 1 m. ![]() Some of the new applications that are expected to be serviced over 5G are HD videos, virtual reality (VR), and augmented reality (AR).įor support of URLLC, 5G is able to provide 99.999% reliability and 1 ms latency (1 ms is 1/1000th of a second). For example, downloading a single 15 GB movie takes at least four minutes for 4G LTE (at the peak data rate of 500 Mbps), but only six seconds for 5G at the peak data rate of 20 Gbps. ![]() 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).Īccording to ITU's definition, eMBB can be characterized by a peak download speed of 20 Gbps and a user-experienced download speed of at least 100 Mbps. 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. In the early 2010s, when 4G LTE technologies were just hot off the press and commercial 4G services were about to take off, many organizations in academia and industry initiated research on next-generation breakthrough technologies with Samsung Electronics leading the pack with its own 5G research initiative in 2011. Since the days of analog technology in the late 1970s, the mobile communication has been continuously evolving with each new generation enabling new services. 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? The LTE technology used in many of our smartphones for voice/video calls or video streaming is 4G. Samsung Research will continue to focus on advanced communication research to strengthen 5G competitiveness, prepare core technologies for the 6G era 10 years later, and lead global standards based on them. In response to the rapidly changing generational change of mobile communication technology every 10 years, major countries around the globe have already launched 6G research and introduced it into fierce leadership competition. The communication technology, which is the foundation of the future society, is evolving to prepare for the future ahead of any other technologies. In addition, ultra-wideband (UWB) technology, which can safely and accurately measure distances, is emerging as a next-generation connectivity technology that connects various devices and provides location-based services. Today, 5G technology is being applied to the core infrastructure of various industries, and is used to support everything from high-quality communication services to smart factories, vehicle-to-vehicle communication, and a raft of other new services. The communication technology will continue to evolve fast to connect people with machines and things through more and faster exchange of information. It is the foundation of a smarter age in which AI and robots will become a common part of our daily lives. The communication technology provides the infrastructure needed to enable people and things (i.e., devices, places, etc.) to connect and interact with one another across physical and virtual spaces. ![]()
