Samsung Electronics Co. together with American wireless carrier Verizon and mobile chip maker Qualcomm Technologies has demonstrated ultra-fast 711 Mbps upload speeds, which would enable fast and seamless data sharing in crowed places like transit hubs and shopping malls.

The uplink speed of 711 megabits per second (Mbps) is equivalent to uploading one 1-gigabyte (GB) movie in about 10 seconds. At this speed, people would easily upload video and pictures on social media or directly share data with other users in densely populated areas. It also allows people working from home to upload and synchronize massive files to effortlessly complete simultaneous editing of documents in cloud, said Samsung Electronics in a press release on Friday.

The upload speed of 711 Mbps is the fastest the companies have achieved ever. Previous multi-gigabit speeds have been recorded on downloads only, Samsung Electronics said.

Demonstration was made in a lab trial by combining “400MHz of Verizon’s 5G mmWave frequency and 20MHz of 4G frequency using the latest 5G technologies, including mmWave carrier aggregation and Single-User MIMO (SU-MIMO),” explained Samsung. Network technology used in the demo also included “Samsung’s 28GHz 5G Compact Macro and virtualized RAN (vRAN) and Core (vCore)” as well as “a smartphone form-factor test device powered by the Qualcomm flagship Snapdragon X65 5G Modem-RF System,” the company added.

Samsung’s Compact Macro is a compact and lightweight solution that can be installed on the sides of buildings and utility poles, enabling swift build-out of 5G networks, according to the press release.
