Solutions
OCC Control System
OL-IN uses LED visible-light communication (OCC) to deliver accurate indoor positioning — no GPS required, within 1 meter accuracy.
System
System Architecture
Three tightly integrated components work together seamlessly.
OCC Transmitter Module
Installed inside LED luminaires, each module continuously transmits a unique ID and position coordinate via modulated visible light.
Mobile App
The OL-IN app uses a smartphone camera to receive OCC signals and display the user's real-time indoor position on a floor map.
Monitoring PC Software
An administrator dashboard that visualizes the positions of all users and assets across an entire facility at a glance.

Technology
What Is OCC?
Optical Camera Communication (OCC) is a communication technology that encodes data into the visible light emitted by LED luminaires, which is then decoded by a smartphone camera. To the naked eye the LED looks like an ordinary light — but the camera sensor reads the unique ID and position coordinates embedded in each fixture's modulated output.
JK Technology independently developed OL-IN, an indoor positioning service built on this OCC technology, achieving 3 patent registrations and 4 technology transfers. OL-IN complies with the IEEE 802.15.7 standard and is optimized for ceiling heights of 2.5 m or above.
Features
Key Capabilities
Precision Indoor Positioning
Achieves positioning accuracy within 1 meter — delivering 3D X/Y/Z coordinates in spaces where GPS cannot reach.
Leverages Existing Infrastructure
No additional cabling or network equipment required. Simply attach the OCC module to existing LED fixtures and the service is live.
Low-Latency Real-Time Service
Camera-frame-rate response speed provides continuous, uninterrupted positioning data with virtually no perceptible delay.
Use Cases
Where OL-IN Works
OL-IN is deployable in any indoor space equipped with LED lighting.
Large Shopping Malls
Turn-by-turn indoor navigation, store locator services, and visitor flow analytics powered by visible-light positioning.
Hospitals & Medical Facilities
Real-time tracking of patients, staff, and medical equipment across large hospital floors for operational efficiency and safety.
Warehouses & Logistics Centers
Automated inventory location tracking and goods-in-transit routing that eliminates manual scanning in large fulfilment facilities.
Museums & Exhibition Venues
Location-triggered exhibit information delivery and visitor path analysis for a richer, more personalized visitor experience.
Smart Buildings & Campuses
Facility management automation — meeting room availability, energy-zone occupancy sensing, and emergency evacuation guidance.
Industrial Facilities & Shipyards
Worker and asset location management in GPS-denied environments such as large vessels, underground plants, and sealed factories.
