RTLS (Real Time Location System)
uses "beacons" (low power transmitters) installed on vehicles, that transmit their ID each 1-5 seconds in 2.4 GHz frequency range. The receiver registers all packets and evaluates the distance to transport (up to 100m). The system operates also indoors (hangars, parkings, under the bridges, etc.) and is more precise.
We developed a RTLS-system for registration and schedule control of city public transport. The system includes readers installed on exits from parkings and on route end points, readers are connected to internet. Reports are available via Internet.
