Idolink, a Korean developer of radio frequency identification, real-time location system (RTLS) and Internet of Things solutions, is bringing its products to North America through its U.S. division, Linkpoints. Its ultra-wideband (UWB) RTLS solution and its ZigBee-based smart-home system, known as OnePass, are already being used in Korea. OnePass provides what Idolink calls a smart-home system for apartments, while the RTLS is being utilized to track the movements of individuals and assets in such places as factories, retail stores and hospitals.

Apartment construction and management company Samsung C&T Corp. has been using OnePass at its Raemian apartment buildings for approximately two years, enabling residents to access elevators and apartments, identify parking spaces, and be located in the event of an emergency. Telecommunications firm SKTelecom is employing the UWB solution as part of its T-Smart Position (TSP) system, which provides users with access to location-based data regarding assets, inventory or individuals.

An apartment resident can use the OnePass tag to locate his car within his building's parking area.
The OnePass system consists of a tag, a receiver and repeaters, as well as cloud-based software for location-tracking purposes, according to Chris Shin, Idolink's president. The tag is powered with a rechargeable battery and transmits its unique identifier via a 2.4 GHz signal compliant with the ZigBee and IEEE 802.15 standards. It also comes with 125 kHz and high-frequency (HF) 13.56 MHz radios for close-range transmission.

Gi-Tak Na, sales team manager for Raemian, says that before the system was installed about two years ago, "residents needed to enter the password on the keypad or use contact RFID cards. Although these methods were intuitive," he says, there were "issues when it comes to security and access control."

For instance, Na says, imagine coming home with hands full, and needing to search for an access card or press an elevator button. "The OnePass system solves this problem," Na states, "by making your access to doors and elevator a breeze, yet in a secure manner."

Each resident is assigned the OnePass tag for an apartment building or complex (typically, four passes are provided altogether for a single unit). The tag then acts as that person's keyless entry, parked car locater and emergency calling device, as well as health information tracker.
