Samsung and KT to pilot NB-IoT in Seoul

Samsung Electronics and Korea Telecom are planning an NB-IoT pilot targeted at friendly users in Seoul and its metropolitan areas over a two-month period, with the aim of extending diverse service models and coverage in near future.
The NB-IoT technology is designed to meet the demands for use cases that require low throughput and battery use owing to its main feature, the narrow bandwidth of 180kHz. With its low-power consumption and cost-effective devices, NB-IoT is applicable to diverse service models for individual and industry automation, such as utility metering, smart factory, cargo tracking, and location tracking of children and goods.
KT will initiate its first NB-IoT pilot service with the location tracking service and further expand on its use cases to diverse business applications.
“KT is launching its first NB-IoT service in Seoul and metropolitan areas thanks to close collaboration with Samsung,” said Chang-Seok Seo, executive vice president of KT. “IoT services will remove boundaries between industries with their ability to connect everything. KT will open up new possibilities of the IoT era by generating unprecedented services and industry convergence.”
Samsung has deployed its latest NB-IoT technology to existing LTE radio base stations and rolled out its virtualised C-GSN cellular IoT core service. Further, interoperability tests between NB-IoT networks and new devices have been completed in advance, since reliable interoperability is a key prerequisite for operators prior to introducing new technologies and services to the market.
“What we have achieved together with KT is a key industry milestone that will accelerate LTE vertical businesses based on IoT technologies,” said Jinsoo Jeong, senior vice president of Samsung Electronics. “As a strategic partner, we provided KT with NB-IoT features complying with all the latest enhancements in 3GPP standard specification in a short period of time to support KT’s pioneering work.”
Back in February 2017, Samsung and KT signed the supply contract for NB-IoT, and two months later the companies are announcing their readiness to start pilot service, which indicates the proximity of commercial service.
One of the key elements included in this contract was Samsung’s C-GSN. As the demand for IoT services continues to grow, the current LTE network needs to accommodate large amounts of connectivity generated from the ever-growing number of IoT devices. C-GSN is claimed to provide better scalability, flexibility, cost-effectiveness and easy operation than other legacy core systems.
