There has been an general increase in the number of accidents in the mountains of Japan, and specifically among foreign tourists, number of accidents have tripled in the past 3 years. The leading cause is the lack of consciousness towards accident countermeasures. We have developed a new service that would change that and therefore decrease the number of accidents.

Base Location : Sony's LPWA-type radio transmission system. By setting antennas in target areas, we created our own 920MHz wide-ranged network.

IOT Device : A lunch box embedded with GPS sensors and an antenna and battery to receive signals from the LPWA system.

Smart Device : Showcased a 3D map created with WebGL for web browsers and apps. We visualized user's location information in real time.

· A lunch box embedded with GPS and long-range wireless communication ability, and a web page that shows real time information in 3D.

· Events in 13 resort locations in Japan

·Established communication between people who enjoy outdoor activities and brands through the lunch box that houses long-distance wireless technology.

The LPWA transmission system is a low-power and wide-area communication system, and the amount of data that can be transmitted is very small.

LifeLineLunchBox utilizes that characteristic to its full extent, and set up antennas across mountains where electricity is limited. By collecting a minimum amount of coordinate data and elevation data in real-time, the system is designed to build a dynamic experience.
