Samsung Electronics has set new records for transmission distance and download speed in a long-distance 5G communication test using the 28GHz frequency.

Samsung Electronics announced on the 7th that in a local test of 28GHz 5G technology conducted jointly with Australian mobile carrier NBN Co (National Broadband Network Company), it achieved an average data download speed of 1.75Gbps and a peak speed of 2.7Gbps at a distance of 10km from the base station. This is the longest transmission distance and highest transmission speed ever recorded with 28GHz 5G communication.

5G communications using ultra-high frequency bands such as 28 GHz provide fast speeds by utilizing wide bandwidth, but the radio transmission distance is relatively short compared to low-band and mid-band frequencies, so technologies that extend the transmission distance affect the quality of the service.

For this purpose, Samsung Electronics installed the latest 2nd generation 5G modem chip developed in-house. In addition, it has applied △28GHz Compact Macro equipment that provides base station, radio, and antenna functions in a single form factor △Carrier Aggregation technology that enables higher transmission speeds by utilizing 800MHz wide bandwidth △3D Beamforming, an antenna optimization technology that enables data to be transmitted further.

In particular, in Australia, which has a low population density and a large land area, it is expected that Samsung Electronics' long-distance 28GHz 5G communication technology will be used to more effectively provide wireless ultra-high-speed broadband services (FWA, Fixed Wireless Access) to suburban areas.

“Samsung Electronics has come one step closer to realizing the infinite potential of ultra-high frequency bands based on its overwhelming wireless communication technology and commercialization experience accumulated around the world,” said Lee Jun-hee, Executive Vice President and Head of Development Team at Samsung Electronics’ Network Business Division. “Samsung Electronics will continue to lead technological innovations that will dramatically transform the next-generation communications environment.”

“The results of this joint trial with Samsung are a significant step forward in bridging the digital divide across Australia,” said Ray Owen, NBN’s chief technology officer. “We are excited to explore the potential of the 28GHz band and create new opportunities to deliver a wider range of high-speed broadband services to Australian consumers.”
