In last November, KT, a South Korea-based telco, formed 'NB-IoT Alliance' with LG U+, aiming to launch NB-IoT service as early as Q1 2017. Later in the month, the company, apparently stimulated by SK Telecom who had just started LoRa-based, IoST-dedicated, commercial services, announced another plan to complete deployment of a nationwide NB-IoT network by June 2017 for faster entry to t...

[Issue analysis-1] IoST era begins with initiatives for a nationwide IoT network deployment IoT, the next generation growth engine in the mobile communication industry, is finally unveiled. South Korea-based SK Telecom and KT, geared up with cutting-edge IoT technologies including LoRa, LTE-M, and NB IoT, etc., are to be in fierce competition to deploy the nation's (and world's) fir...

Before we begin.. On March 10th, the Ministry of Science, ICT and Future Planning (MSIP) of the South Korea announced it would adjust the output power in unlicensed 900MHz band from the current 10mW to 200mW as an effort to stimulate the emerging IoT-related industry. The big 3, fueled by the announcement, are aggressively seeking ways to deploy IoT infrastructure. On March 18, SK Telec...

들어가기에 앞서.. 지난 3월 16일 미래부가 IoT 신산업 활성화를 위해 IoT 주파수로 활용될 900 MHz 비면허 대역의 출력 기준을 10 mW에서 200 mW로 올린다고 예고하였다. 미래부의 IoT 신산업 활성화 추진에 따라 이동통신 3사가 적극적으로 IoT 인프라를 구축하고 있다. 미래부 발표 직후, 3월 18일 SK 텔레콤은 세계 최초로 IoT 전용 전국망을 연내 구축한다고 발표했다. 이 IoT 전용 전국망은 LoRa 기반 저전력 광역통신망 (Low Power Wide Area Network; LPWAN)으로 LTE 망과는 별도로 구축되며 LTE를 무선 backhaul로 이용한다. 3월 28일에는 LG 유플러스가 LG 이노텍과 소물인터넷 전용 LTE 통신모듈을 출시하며 이 모듈...
