Internet of Things(IOT)

Internet of Things is a technology that connects sensors and communications to the Internet through the wireless communication. It refers to the technology that connects many kinds of objects, and we have experience in building various indoor location tracking solutions by using this technology.

Vicon-based indoor location tracking

We build to track the location of equipment that received the beacon signal by using Vicon-based indoor location tracking.

  1. The way of determining the current location according to the ID of beacons The bacons have the receiving radius of up to 70 meters and are set up at regular intervals
  2. The accuracy of the location is in proportion to the number of the beacons installed

Wi-Fi-based indoor location tracking

It can track the location of the equipment receiving the signals through the value of RSSI(Received Signal Strength Indicator) from Wi-Fi repeater(Access Point).

  1. It is possible to track the location by three AP(Access Point) according to the triangulation theory, but it has lower accuracy as indoor objects, equipment, or people prevent it from tracking
  2. The accuracy is increasing as there are less indoor objects and more AP(Access Point)

Mobile-based indoor location

It can help figure out the location that is relatively moved from the previous location as accumulating the information of moving direction and moving acceleration by using the 6-axis gyro acceleration sensor and the geomagnetic sensor embedded in the mobile.

  1. It should set up an initial location. Also, it occurs the error of the accuracy of the sensor with accumulated location information. So, It has to use beacons and Wi-FI simultaneously to make up for those faults
