ROHM Introduces Guidepost CellLocation Detection Infrastructure Energy-Harvesting DSC
ROHM, in collaboration with Ritsumeikan University and Information Services International – Dentsu, Ltd., recently announced Guidepost Cell, a unique indoor location detection infrastructure that supplies highly precise positional data to smartphones and other mobile devices to determine a user’s location inside buildings, underground malls and other interior areas using low-power 802.11-compliant wireless beacon protocol.
A vaIn response to this burgeoning market need, ROHM, Ritsumeikan University and ISID co-developed Guidepost Cell technology, which utilizes advanced location detection and energy harvesting methods to enable an expected positional accuracy within 1 meter, while requiring no external power source for operation.
Key Guidepost Cell Benefits:
• High-accuracy location detection — Configuring its Wi-Fi infrastructure for indoor location detection instead of communication using low-power beacon transmission enables Guidepost Cell to provide high-accuracy location detection with minimal power consumption
• Low operating costs — Guidepost Cell utilizes ROHM’s dye-sensitized solar cell technology that efficiently harvests energy from indoor lights, eliminating the need for an external power supply while reducing installation and electricity costs
• Application compatibility — Standard 802.11 wireless transmission protocol ensures compatibility with smartphones and other portable devices
Dye-sensitized Solar Cell
Key Features:
• Designed to generate electricity efficiently under indoor lighting. Industry-leading power generation: 48μW/cm2 under 1000 lux
• Available in various shapes, sizes, and colors to fit a number of applications. (In contrast to its competitors, ROHM is focusing on R&D of compact high-efficiency DSCs.)
Applications:
• Indoor power sources for low-power electronic devices such as wall clocks and calculators as well as next-generation systems such as indoor sensor networks.
