WiMag Vehicle Detection

Complementing the company’s proven loop and radar detection solutions, WiMag provides vehicle and bicycle detection systems using low power wireless technology to transmit data to host controllers. The WiMag solution uses battery-powered wireless sensors installed beneath the surface of the road, sending information to the traffic controller without the need for expensive cabling or duct works.

Why WiMag VD

The installation, maintenance and removal of ducting and cabling in the highway is typically costly and time-consuming, leading to increased impacts on the road network. Siemens WiMag provides an alternative solution in favour of a faster, easier and more cost-effective detection system.

Each WiMag detector is placed into a small hole that has been ‘cored’ in the carriageway surface which is then fixed in place with epoxy resin.

Equipped with sophisticated wireless technology and a dedicated battery, the detectors can operate effectively for extended periods expected to be up to 10 years, with a warranty period of 5 years.

Wireless Transmission

With in-built wireless transmitters/receivers, the detectors communicate with nearby Access Points or battery-powered Repeater units that are typically installed above traffic signal heads and on suitable poles. The access point serves as a wireless gateway to maintain connection with the detector and effortlessly establish overall time synchronisation. Configuration details are also managed and sent through the access point to other devices whilst receiving and processing all data gathered from the detectors.

In larger installations, the Repeater units can be used to extend the range between an installed detector and the access point up to approximately 300m. Two repeaters can operate in tandem for an even further distance (up to 600m) to facilitate a larger, more extensive, detector network.
