Active High Speed Infrared Communication by EFKON
Infrared radiation (IR radiation) is electromagnetic radiation with a wavelength between 0.7 and 300 micrometers. Direct sunlight also includes infrared , which is part of the heat radiation and invisible for the human eye. Infrared is, in fact, a necessary form of energy that all living things require for optimum health. Infrared is completely safe and natural.
EFKON was the first to employ Active Infrared for directional outdoor payment applications. EFKON is the leader in infrared technology, offers the most advanced infrared technology and solutions to our customers. Active IR Communication Technology has also been established as medium for ETC, car to infrastructure and car to car communication.
ISO CALM Infrared Technology
To create a powerful and standardized solution the ISO CALM concept (Communication Access for Land Mobile) was introduced. ISO CALM is a family of international Standards (ISO 2121x) which shares a common architecture, common network protocols and air interface definitions for wireless communications. ISO CALM supports multiple media, like Cellular 2nd and 3rd Generation, 5 GHz Microwave and Active Infrared communications.
Which Business Fields uses Infrared Technology?
ETC (Electronic Toll Collection)
The collection of toll fees at toll plazas, SL (Single Lane) and ML (Multi Lane) Free Flow installations as well as in the context of Stop&Go applications is performed by active Infrared (IR) data transmission from the On Board Unit (OBU) over IR transceivers to the Control Unit and Back End. Additionally Efkon’s Contactless Smart Cards (CSCs) or MIFARE Smart Cards from other suppliers can be used together with OBUs.
Parking & Access Control
Intelligent Active Infrared transceivers are installed at car park entries and exits or parking areas to control and ease access by performing the data transmission together with an OBU.
Intelligent Transportation Systems (ITS) for the Future
ISO CALM based High-Speed Bi-Directional Active Infrared is used as main technology for infrastructure-to-car and car-to-car communication for several applications within the ITS sector, such as Fleet Management, Container Management, Public Transport or Traffic Information Systems. Accident, incident or weather warnings as well as roadwork, lane utilization, traffic congestion, speed limit or road charging information is transmitted in real-time to the driver.
