With the groundwork for 5G technology finally approved by the ITU, companies are continuing to test the hardware needed to make the faster speeds a reality, hopefully sometime in late 2018. The latest successful test by Samsung involved a moving train, a 5G radio, and a 5G router.The result was a blazing 1.7Gbps peak speed.
The test took place in Saitama, Japan, last month, with the public transit train traveling between two stations about a mile apart, "composed of a 5G router (CPE), radio access unit (5G Radio), virtualized RAN and virtualized core," according to a release by Samsung. The train was traveling at about 100 kilometers per hour, with the test successfully downloading an 8K video and uploading a 4K video during the run.The test was run in conjunction with South Korean telecommunications company KDDI.
“With 5G expected to bring railway services to a whole new dimension, the success of today’s demonstration in everyday locations such as a train and train station is an important milestone indicating 5G commercialization is near,” KDDI Senior Managing Executive Officer Yoshiaki Uchida said in a statement. “To fulfill our aim to launch 5G by 2020, KDDI will continue exploring real-life scenario experiments for diverse 5G use and business cases together with Samsung.”
The success comes on the heels of another positive result from February where Samsung and KDDI accomplished a similar result in a car moving through the streets of downtown Tokyo. That test was divided into two scenarios: First, a 5G device mounted on a vehicle traveling at 60 kilometers per hour drove between two 5G base stations on a busy expressway; the second, tested the performance of the 28GHz spectrum. The test achieved 3.7Gbps.
Samsung actually did a similar 5G test three years ago in a moving car traveling at the same speed. Then, the result was an amazing (for the time) 150Mbps download speed.
