[Korea ohahreum financial newspaper News] Samsung Electronics and KT 'narrowband Internet of Things (Narrow Band - Internet of Things, hereinafter NB-IoT)' communication solutions, has signed a supply agreement announced Tuesday.
NB-IoT are a number of Internet of Things (IoT) technology to connect to the terminal last year, low-power wireless communication in June the international 3GPP mobile communications standards bodies have established a complete international standard.
Samsung Electronics is expected to collectively advance this month to a base station software upgrades, and replace older base stations NB-IoT dedicated virtualized core (vCore) to enable KT to build the network of the NB-IoT commercial service during the first half of this year.
NB-IoT commercial services when the public and the industry seems to be particularly useful in fire smoke sensor, for intrusion detection security sensors, patient screening monitoring, power meter, subway line management functions such as remote sensing, reading begins.
Also in the day-to-day with the NB-IoT module in mountaineering jacket to prevent automatically sent a distress alert to relief organizations or camping, or when the body detects your theft sensors and a tent with a fire sensor, fire accident when he was the distress of climbing and the like are convenient and can be a safe and innovative services.
NB-IoT is that while traditional "mobile communication network based on IoT services (Cellular IoT) '△ high battery consumption, which was pointed out as a limitation of △ short indoor coverage △ expensive communication module prices, authentic things, problems with the technology improved dramatically, such as an Internet service It is expected to contribute to popularization.
NB-IoT is the life of the battery goes over 10 years IoT communication terminal because it uses less bandwidth of 200KHz of only about one hundredth of a conventional contrast 4G LTE.
It can also be used as traditional mobile phone base station coverage. In particular, the base station as well is expected to be able mountainous areas, since it is possible that the underground space and other services via the repeater is installed on the LTE shaded area in fact be the NB-IoT services in all regions compactly as possible the existing LTE services.
It can also greatly save the cost of building the infrastructure necessary for the new service because they can leverage the existing infrastructure of the base station and antenna and other major 4G LTE service is built on.
Equipment in particular SEC supplied to KT, even if adding the NB-IoT service to the existing LTE communication equipment due to utilize a separate buffer band of a guard band (Guard Band) for preventing interference between frequency bands and the bands existing LTE quality of service has no effect.
KT Giga IoT Project Director gimjungeun, managing director of "NB-IoT is the most efficient technology for low power objects Internet service expects to welcome a full-fledged flowering World IoT market through this," said the cooperation with domestic and foreign companies, including the "Samsung NB-IoT ecosystem based on the composition, and I will open a full-fledged Internet of things era signaled the first half of this year, domestic service, "he said.
Samsung Network Division Jung, Jin - Soo, Managing Director provides the central rapid and reliable communications solutions, domestic and international large carrier, including "KT will be expected to jump into the IoT market NB-IoT competition rages will do my best to lead the IoT market "he said.
