The Guidepost Cell is an 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. It is based on energy-harvesting DSC (dye-sensitized solar-cell) technology that resolves installation and maintenance problems normally associated with wireless beacon terminals.
The company, together with Ritsumeikan University and ISID, co-developed Guidepost Cell technology, which uses advanced location detection and energy harvesting methods to enable an expected positional accuracy within 1 m (3’), while requiring no external power source for operation. Key feature of DSC is that it is designed to generate electricity efficiently under indoor lighting. Industry-leading power generation: 48 μW/cm2 under 1,000 lux.
