Samsung Electronics has set a world record for upload speed using 5G mobile communication technology.
Samsung Electronics announced on the 15th that it recorded the 5G upload speed of 711Mbps at the recent trial conducted together with mobile carrier Verizon and telecommunication technology company Qualcomm in Plano, Texas, the U.S.
This speed can upload a 1GB (gigabit) video file in 10 seconds. Compared to the existing download speed, it is about twice as fast.
It has doubled the existing upload bandwidth of 200㎒ by applying carrier aggregation technology that uses more than two frequency bands to the Samsung Electronics’ mmwave compact macro equipment, and made possible to upload fast by applying MIMO (multiple-input and multiple-output) technologies that that utilizes multiple antennas at the same time.
Samsung Electronics said this technology enables to take and upload high-quality videos to the cloud and SNS anytime, anywhere.
In particular, various content can be produced and spread by easily sharing vivid videos taken at concerts and sports stadiums. Also, it can easily share high-volume data and hold high-resolution video conference, making it easy to work from home.
In addition, Samsung said that since high-resolution video upload is possible, it can be widely used in 5G services for enterprises such as defect detection process by using image analysis AI (Artificial Intelligence) technology.
“Through the collaboration with Qualcomm and Verizon, we will able to provice differentiated 5G experiences and deliver more immersive mobile services for users,” said Junehee Lee, Executive Vice President and Head of R&D, Networks Business at Samsung Electronics. “By developing new technologies and collaborating, we will drive various 5G technology breakthroughs that will transform people and enterprises’ communication environment.
“We are speeding up millimeter wave investment as a critical differentiator that can quickly acuire mid-band 5G coverage and provide new experiences and solutions to people and companies,” said Adam Koeppe, Senior Vice President of Technology Planning for Verizon. “Currently, we have over 30,000 cell sites for mmWave, and are planning to expand our investment further,” said Koeppe.
“Enhancing upload speeds shows the new possibilities of 5G mmWave, which will be used in transit hubs, downtown areas, shopping malls and ultra-high speed internet service,” said Durga Malladi, Senior Vice President and General Manager for 5G business at Qualcomm. “Our collaboration with Samsung and Verizon is the best practice of efforts to commercialize 5G mmWave and secure new user experiences.”
At this trial, Samsung Electronics' 28㎓-band 5G cell site, 2.1㎓-band 4G cell site, and vCore (virtualized core) were used.
The upload speed was measured by test smartphone device with Qualcomm gen 4.0 mmWave 5G modem-RF system (Snapdragon® X65).
