HFI's RF800 indoor geolocation system leverages professional-grade radio communication networks to precision-locate staff inside buildings. The system is compatible with the latest digital mobile radio network (DMR and pDMR) standards and can be used with the latest professional-grade walkie-talkies. The latest version of the RF800Z uses a UHF mesh network to locate personnel wearing a compact receiver manufactured by HFI. The system is totally self-powered, independent from the facility's communication networks, and easy to implement, test, and maintain. In addition, the frequencies used ensure effective indoor coverage with minimal infrastructure requirements. The system responds to increased demand for location systems for industrial facilities, office buildings, and parking facilities and can enhance isolated worker protection, maintenance, and operations. The initial standard version of the solution has already been implemented at several airports, prisons, shopping malls, and factories.

L'histoire du produit

HFI initially developed an indoor geolocation system that combined a simple fixed UHF beacon and receiver setup with a DMR or pDMR network to send location data to an application server. To use the system, personnel had to carry walkie-talkies equipped with HFI chips to receive the signals emitted by the beacons. This ultimately evolved into a system where the UHF beacons could communicate with each other via a mesh network, with location capabilities still based on UHF beacon-receiver communication. However the data is transmitted to the server via the UHF mesh network, which is completely separate from the location system. This improvement, developed in conjunction with Grenoble Institute of Technology-Esisar students with the support of the Easytech program, will allow the location system to be used outside of professional-grade radio environments. The mesh network's main features were developed in conjunction with the students, who participated actively in the needs analysis, market intelligence, functional and technical specifications, and hardware and software development phases of the project.
