Samsung and KDDI recently achieved a major milestone by successfully testing 5G networks on high-speed trains, reaching a peak speed of 1.7 Gbps. This marks the first time Samsung has demonstrated 5G technology in such a setting, showcasing the potential for seamless connectivity even at high speeds. The test took place in Japan, where Samsung Electronics announced on the 1st that it had partnered with KDDI Corp., a leading Japanese telecom company, to conduct this groundbreaking trial.
The demonstration involved a train traveling at over 100 km/h, proving that 5G can maintain strong signal strength and fast data transfer rates even under challenging conditions. This development is a significant step toward enabling reliable in-vehicle Wi-Fi, which promises greater security and performance compared to previous technologies.
During the test, Samsung and KDDI used a 5G router installed in the train to download an 8K video and upload a 4K video without any issues. This shows the real-world application of 5G in mobile environments, paving the way for future innovations in connected transportation.
The collaboration between Samsung and KDDI has been ongoing since 2015, and this latest achievement highlights their commitment to advancing 5G infrastructure. KDDI also emphasized its plans to continue working with Samsung to meet the goal of launching a full 5G network by 2020.
Meanwhile, Ericsson, a leading Swedish telecom equipment provider, predicts that 5G will see rapid growth in the coming years. According to their semi-annual Mobility Report, by 2023, 5G is expected to reach one billion users globally. Ericsson also estimates that 5G will cover more than 20% of the world's population within six years, significantly boosting mobile data traffic.
The report further notes that mobile data traffic will grow eightfold by 2023, reaching 110 EB per month—equivalent to 5.5 million years of HD streaming. The first commercial 5G networks using New Radio (NR) technology are expected to launch in 2019, with widespread deployment by 2020. Countries like the U.S., South Korea, Japan, and China are set to lead the global 5G rollout.
This progress underscores the transformative potential of 5G, not only in improving internet speeds but also in enabling new applications across industries, from smart cities to autonomous vehicles. As companies like Samsung and KDDI continue to push the boundaries, the future of wireless communication looks more connected than ever before.
When you think of the screen protectors of old, you're probably thinking of TPU. It's a flexible plastic that's a huge hassle to install . it's flexible, so it can go edge-to-edge on any phone, it has better impact protection than PET, and it has limited "self-healing" powers for small scratches. Brands like TUOLI offer TPU at very affordable prices,
On the other hand, TUOLI's comes in a few different styles depending on the look, feel, and features you want.
