Samsung and SK Telecom Complete 5G NR Trial

Samsung has announced the successful completion of a 5G trial, based on 5G New Radio (NR) technology.

NR technology is the global 5G standard intended to provide a standardized OFDM-based air interface to support next-generation 5G deployments, services, and spectrum. NR technology promises customers stable, fiber-like connections provided at low cost, with low latency.

The results achieved in the Samsung trial included speeds of over 1 Gbps, leveraging a wide channel bandwidth of 80 MHz to make consistent gigabit performance feasible. In addition, the companies were able to transmit with an ultra-low latency of 1.2 MS. The latency was achieved by reducing the comparable transmission time interval (TTI) by 75% of the 4G rate, for a 5G TTI of 0.25 MS.

Dongsoo Park, Executive Vice President and Head of Global Sales and Marketing for Samsung Networks, said that the trial was a significant development in the effort to commercialize 5G and accelerate the rollout of the new technology.

“We achieved another milestone today, taking 5G into the sub-6GHz spectrum for use cases and applications requiring wider area network coverage,” he said. “The below 6GHz spectrum has been identified by the industry as ideal for enabling 5G services such as autonomous/connected car that require a wider area network.”

Samsung and SK Telecom were able to make a successful 5G end-to-end connection on the 3.5 GHz spectrum at the Samsung R&D center in Suwon, also known as the ‘Samsung Digital City.’ The trial was comprised of Samsung 5G virtualized core and RAN, with test devices based on 3rd Generation Partnership Project (3GPP) standards for New Radio technology.

The 3GPP unites various telecommunications standards development organizations and looks to combine expert recommendations to create a global standards framework for international development of telecommunications systems. The Samsung trial was conducted using devices conforming to the latest 3GPP NR standards which include numerology, frame structure and channel coding.

SK Telecom and Samsung committed to further exploration of the unique attributes of high and low frequencies, and how they may be used to optimize 5G applications. For example, using an ultra-high frequency like 28GHz allows the transmission of large volumes of data at high speeds, due to wide bandwidth availability. Alternatively, using a frequency below 6GHz, such as the 3.5GHz frequency used in the trial, promises more stable coverage for users.
