All three telecommunications companies have similar technologies in measurement, monitoring, tracking, and vehicle control.

“When we talk about NB-IoT, we think of building a new network. While there have been cases where dedicated base stations were built, the nationwide network was expanded while maintaining the existing LTE network,” said KT Team Leader Park Yoon-sung. According to Team Leader Park, the technological level of NB-IoT is such that the communication network is about 1.2 times wider than that of LTE.

The three telecommunications companies (KT, SKT, and LG Uplus) participated in the International Internet of Things Exhibition and introduced their respective IoT communication modules and related services.
Team Leader Park said, “We built an NB-IoT network in July and made the communication chip into a general module.” "We are currently developing about 55 related devices," he stated.

Pointing out that communication connecting telecommunications agencies and consumers is difficult when venture companies or individual business owners launch devices due to the simple structure of IoT devices, they stated, “We revised the exclusive terms and conditions with the Ministry of Science and ICT to allow venture companies to activate services directly.”

KT’s commercialization cases include LP gas control equipped with NB-IoT, Daime Pola Special Vehicles Co., Ltd., which controls the remaining tank quantity and refueling route of LPG gas cylinders, and controls the refueling amount and movement location, Glosscom Co., Ltd., which provides information on LP gas containers and tanks and controls the remaining tank quantity and refueling route, and Daou Funda Co., Ltd., which provides various information such as customer location, battery status, and communication sensitivity, and remotely controls the remaining LG gas tank quantity and gas meter usage.

SK provides measurement, monitoring, tracking, and vehicle control as IoT services.

Na Kyung-hwan, a team leader at SK’s IoT business division, stated, “While consumers find IoT services convenient, they are skeptical about paying additional costs,” adding, “Because IoT services are fragmented, it is difficult to reach a level where economic benefits can be obtained, so we are considering ways to enhance economic viability through data analysis.”

As a related example, the LiveCare service was introduced, which measures the body temperature of cattle on farms to prevent disease and predict the optimal timing for insemination. The method involves inserting a sensor about half the size of a mobile phone into a cow, which has four stomachs. Data is transmitted once a day, allowing the battery to last for five years. Considering that the slaughter period for cattle is generally within 3 years, battery life is not an issue.
It monitors in real time the condition of facilities with potential collapse risks, such as temporary building frames at construction sites, buildings less than one year old passing through the thawing season, and old facilities. It measures the angle, tilt, and atmospheric pressure of the building and sends a warning alarm to the user if they exceed danger thresholds. Among U+’s industrial sectors, Vehicle Control IoT is a service that manages vehicles without the need for separate device installation. It provides vehicle information to freight vehicles, where transport directly translates into revenue. Once the app is installed, it supports departure and arrival notification services based on vehicle location, eliminating the need to monitor the vehicle. Drivers can view statuses such as driving, resting, loaded, or empty within the app. The vehicle control channel can dispatch additional shipments by determining whether a freight vehicle is empty, the number of vehicles currently in operation or have completed a trip, and the average driving distance.
