Innovative parking solutions feature heavily in Q-Free’s exhibit here at this year’s ITS World Congress. The company’s new ParQSense sensors, which launch in early 2018, will combine class-leading detection capabilities with a new communication protocol to make deployments of on-street parking sensors far simpler and less expensive.

By combining radar and magnetometer technology with advanced data analysis, ParQSense gives over 99 per cent detection accuracy.

This outstanding performance can be allied to the emerging NB-IoT (Internet of Things) communication protocol which uses modified cellular network base stations to provide multiple narrowband communication channels with low data rates, good range, and low transmitted power. It is ideal for supporting localised sensor networks.

Q-Free’s long experience of producing tolling on-board units with low power needs, and NB-IoT’s low transmitted power, result in a compact, battery-powered sensor with a life of a decade or more, says Michael Eimstad, Q-Free’s senior commercial manager parking.

“Two versions will be offered. The ParQSense ITS-420 uses sub-GHz, license-free radio to communicate to a local Q-Free base station. The ParQSense ITS-421 will use NB-IoT and will not need a base station,” Eimstad said. “NB-IoT is real a game-changer. Being able to use existing cellular networks means that there is no need to approve, install and maintain discrete communications solutions.

“We carried out tests to prove the technology earlier this year, and we’re delighted with what we’ve achieved. It won’t just revolutionise parking; it also places us at the forefront of open-standards communication for other ITS and smart city applications,” Eimstad added.
