Smart City

LoRa streetlight management system

City of Amsterdam, Netherlands

The City of Amsterdam has been very actively engaged in the smart city development. Upgrading the streetlighting infrastructure with new technology was therefore high on the wishlist of the City.

Applying new technology for smart lighting

The choice of the City of Amsterdam for Redsalt was based on the fact that Redsalt was able to deliver a Proof of Concept within 6 weeks based on the new LoRa Technology.

Redsalt, as an innovative IoT solution provider and system integrator, is very experienced in delivering solutions based on newest technology.

Old Infrastructure limits smart city initiative

The network infrastructure for street lights, traffic lights and video cameras dates from the 1960s. It is not designed for the amount of data it currently transports. Upgrading the infrastructure in a traditional manner is very expensive and impacts the traffic in the city. New cables have to be dug in and replace the old cabling. The CoA was looking how new technology could improve their business case for upgrading the infrastructure.

Wireless connection

Redsalt built a LoRa based connector that can be integrated in the existing infrastructure. This way the disruption is minimal and all infrastructure can be retrofitted very fast. The connector box communicates via the KPN LoRa network with the ThingWorx platform. The platform enables the user to control the streetlights, like turning them on/off or setting detailed schedules.

Technical Specifications

Main technologies:

  • KPN LoRaWAN wireless connectivity
  • ThingPark
  • ThingWorx Internet of Things Platform Application
  • Node.js
  • Custom hardware with Coretex-M3 MCU and SX1272 LoRa transceiver.


The Proof of Concept showed that an alternative infrastructure can be set up very quickly at a fraction of the cost of traditional infrastructure. The integration of the KPN LoRa network, the IoT platform of ThingWorx and custom-made hardware made it possible to disrupt traditional infrastructure solutions.
