Smart city connectivity

Smart City Connectivity

The streetlight network as an IoT infrastructure

Public lighting is one of the city’s most widespread infrastructures. With the right architecture, it can do more than control luminaires.
 
GreenStreet connects cabinets, luminaires, gateways and compatible street-level devices into a standards-based infrastructure for public lighting control, IoT connectivity and smart city integration.
 
This gives municipalities a practical way to manage lighting today – while keeping the infrastructure ready to connect with wider city systems when the need is clear.

Standards and Integration support

Devices

Zhaga · NEMA · DALI/D4i

Standardised interfaces help prepare luminaires and connected street-level devices for control, data and future upgrades.

Network

Wirepas · LTE · Ethernet

At street level, all GreenStreet devices form a selfhealing mesh including strategically placed gateways, creating communication path between field devices and to higher-level systems.

Platforms

TALQ · FIWARE · APIs · External CMS

Open interfaces support interoperability, data exchange and integration with wider city and luminaire control -platforms.

Architecture at a glance

Connected luminaires, cabinet controllers and other wirepas compatible equipment can communicate through the street-level mesh network.

Gateways move data from the field network to management systems and external platforms.

GreenStreet Vision provides operational control, visibility and structured lighting data.
 
Open interfaces support integration with external systems, platforms and municipal applications.

Integration with external systems

GreenStreet can support integration with systems beyond the lighting platform itself.

This may include external CMS systems, GIS, asset management platforms, issue tracking systems, work order tools and smart city platforms.
 
The purpose is to make lighting data available where it creates operational or strategic value – without forcing every municipality into the same system architecture.
External CMS systems
For TALQ-based interoperability and multi-vendor lighting management.
 
GIS and asset management
For connecting lighting assets to location, ownership, lifecycle and maintenance data.
 
Issue tracking and work orders
For connecting alarms and deviations to operational workflows.
 
Smart city platforms
For using lighting and sensor data in wider city applications.

Expected Impact

Reduced lock-in
Standards-based interfaces support greater flexibility in procurement, integration and long-term system development.
 
Street-level IoT infrastructure
The lighting network provides a communication layer for compatible sensors and devices, allowing data to report upwards through gateways into lighting systems or wider smart city platforms.
 
Better data structure
Lighting, asset and operational data becomes part of a wider municipal data environment.
 
Future-ready operation
Municipalities start with lighting control and add integrations, sensors and data services when there is a clear need.

Example use cases

Smart City Examples

The streetlight network support more than lighting.

These examples show how connected public lighting can become a practical foundation for future city services – by enabling local power, carrying data from street-level devices and adapting public spaces to changing conditions

Powering IoT devices

Connected city services need both communication and local power.

Where constant power is enabled, selected parts of the lighting network can support IoT devices such as environmental sensors, traffic sensors, counting devices or digital signage. These devices can be powered locally, connect through the street-level network and report data upwards to management systems or smart city platforms.

Traffic Measurement

Road lighting can be adapted to real traffic conditions, not only fixed night-time schedules.

By connecting traffic flow data to the lighting infrastructure, municipalities could adjust dimming levels according to actual road use. 

This is especially relevant near arenas, event venues or major roads, where standard dimming schedules may not match evening traffic peaks.

Engaging Lighting

Connected lighting can help public spaces reflect what is happening in the city.

Selected monuments, landmarks or public areas could be adapted with event-specific colours for occasions such as Pride, local sports events or cultural celebrations. This gives municipalities a flexible way to create atmosphere and strengthen place identity without changing the physical installation.

FAQ

Standards and Integration

TALQ is an open protocol for interoperability between central management systems and outdoor device networks. In smart street lighting, it helps lighting infrastructure communicate across vendor boundaries and reduces dependency on closed ecosystems.

GreenStreet Vision supports FIWARE-based data exchange, allowing lighting, asset and sensor data to be shared with wider smart city platforms and applications.

Using harmonised data models, municipalities can combine public lighting information with data from other city domains — such as traffic, parking or environmental monitoring. This can support shared dashboards, analytics, digital twins and new cross-domain services.

The data and functions available depend on the connected assets, selected data models and agreed integration scope.

Yes. Through TALQ-based interoperability, GreenStreet has a feature rich TALQ certified Gateway certified since 2025 and support integration with external central management systems where the system architecture and project requirements call for it.
This is relevant for municipalities that want multi-vendor flexibility or already work with an existing CMS environment.

Yes. GreenStreet Vision is a TALQ certified CMS and connect compatible external lighting control networks.

This gives municipalities the option to bring lighting managed by different control systems into one operational environment, with a shared view of assets, status, alarms and performance.

The information and functions available depend on the TALQ capabilities exposed by each external system and the agreed integration scope.

With street-level mesh communication, compatible sensors and devices can route data through the lighting network towards gateways and onward to GreenStreet Vision, external CMS systems or smart city platforms.
This means the public lighting network can become a practical IoT infrastructure layer, not only a control system for luminaires.
Zhaga provides a standardised luminaire interface for controllers and sensors. DALI and D4i support digital communication inside the luminaire, including control, driver information and asset-related data where correctly implemented.
This becomes especially important when municipalities want reliable asset data, future-ready luminaires and better lifecycle management
Yes. Capelon is evaluating DECT-based communication as a possible future communication path for selected IoT connectivity scenarios.
Availability and suitability will depend on project requirements, compatibility, coverage, security and technical validation.
No. Openness means the architecture supports structured integration through standards and interfaces.
Each integration still needs a clear use case, data ownership, security review, configuration and implementation work.
