[Asia Economy Reporter Han Jinju] Samsung Electronics has succeeded in achieving a download speed of 8.5Gbps, the first among 5G base stations.
On the 14th (local time), Samsung Electronics announced through its global newsroom that it achieved the fastest 5G download speed among commercialized base stations in an experimental environment combining MU-MIMO (Multi-User Multiple-Input Multiple-Output) technology operating on 28㎓ 5G millimeter wave (mmWave) and 800㎒.
Samsung Electronics used two test devices, each achieving a download speed of 4.3Gbps, and reached a combined speed of 8.5Gbps with both devices. The test was conducted at the Suwon plant, measuring the total speed in an MU-MIMO environment using the 28GHz 5G integrated base station (Access Unit) unveiled last October and two test terminals.
8.5Gbps is a speed capable of simultaneously streaming HD-quality (720p) video to 2,900 people. Utilizing multi-gigabit speeds can enhance the 5G mobile service experience. Mobile carriers can use this for ultra-high-speed services such as 4K or 8K streaming, augmented reality (AR), virtual reality (VR), and smart factories, while also managing dense traffic distribution in places like subway stations, large stadiums, or concert halls.
This test is significant because it achieved high speeds in the millimeter wave band. 5G is characterized by the simultaneous use of the Sub-6㎓ frequency band below 6㎓ and the ultra-high frequency millimeter wave band above 24㎓. The high-frequency band has narrower coverage compared to the low-frequency band and is more susceptible to path loss or obstacles, but it has the advantage of transmitting large-capacity data quickly.
Utilizing the millimeter wave bandwidth can provide multi-gigabit speeds and is expected to enable innovative 5G service offerings. Currently, several countries including Japan, Korea, and the United States have allocated 5G millimeter wave frequencies, and more than 15 countries are expected to join the 5G millimeter wave lineup.
A Samsung Electronics official stated, "Samsung Electronics is leading the advancement of 5G millimeter wave technology, and the successful test results demonstrate the potential for millimeter wave to provide new business cases while offering opportunities to mobile carriers," adding, "We look forward to pursuing technological innovation to drive the journey toward an innovative millimeter wave ecosystem."
