Standardized data layers
for smart cities.
We deploy and operate open-source, standard-compliant context data layers using the FIWARE ecosystem, turning fragmented sensor feeds into a unified digital twin of the territory.
Data Flow
The FIWARE Architecture Blueprint
Our implementations bridge physical sensors to analytical databases using ETSI-standardized NGSI-LD APIs, preventing vendor lock-in.
IoT Sensors
Streetlights, waste bins, air quality, water flow meters.
FIWARE IoT Agents
Translates native binary, JSON, or UltraLight payloads into standardized NGSI-LD format.
Orion Context Broker
Stores the current entity state and processes context updates. Manages publishers and subscribers.
Cygnus / Comet
Syncs real-time changes to historical timeseries databases.
Case Study
Smart City Platform for Extremadura, Spain
We designed and delivered the core context integration layer serving multiple municipal networks across the region of Extremadura, Spain. The project required consolidating data streams that were originally siloed across proprietary vendor platforms.
By leveraging the Orion Context Broker and configuring physical gateways via LoRaWAN and MQTT, we established a single, unified data repository compliant with the Spanish National Interoperability Framework (ENI) and European standards.
The Technical Challenge
Three separate municipal service providers (lighting, sanitation, and air monitoring) ran independent databases. Combining this data for analytical decision-making originally required slow, batch-processing ETL routines that could not trigger real-time municipal alerts.
Our Solution
- Smart Street Lighting: Connected street cabinets using LoRaWAN node controller units, mapping telemetry to the standardized
Streetlightsmart data model. - Air Quality Networks: Configured municipal environmental stations to publish particulate matter levels ($PM_2.5$ and $PM_10$) directly via an IoT Agent.
- Timeseries Storage: Configured Cygnus persistence workers to parse context updates and sink them to a clustered TimescaleDB database for historical performance queries.
Smart Infrastructure
Production-grade IoT Verticals
Specific implementations built and running in Extremadura using standard context interfaces.
Smart Street Lighting
Real-time control cabinet telemetry, automated dimming schedules, and consumption profiling using MQTT and standardized Streetlight data models.
Air Quality Networks
Continuous monitoring of particulate matter ($PM_2.5$ and $PM_10$) via LoRaWAN, automatically publishing health alerts to open data portals.
Waste Management Sensors
Ultrasonic fill-level sensors tracking waste containers, optimizing garbage truck collection routes to reduce city fuel consumption.
Expertise
FIWARE Engineering Offerings
We build and manage context data ecosystems using open specifications.
Context Broker Provisioning
Deploying Orion, Scorpio, or Stellio brokers on Kubernetes. We configure clustering, persistence tuning (MongoDB/PostgreSQL), and subscription delivery guarantees.
IoT Agent Operations
Setting up multi-protocol IoT Agents (JSON, UltraLight, LwM2M) to parse and map raw device payloads into standard-compliant JSON-LD context structures.
Smart Data Modeling
Mapping proprietary device payloads to international Smart Data Models, ensuring semantic compatibility across municipal portals and open data registries.
Time-Series Archiving
Deploying Cygnus, QuantumLeap, or STH Comet sinks to automatically push context events into TimescaleDB, PostgreSQL, or ClickHouse for long-term telemetry analysis.
PEP Proxy & Security
Hardening endpoints using FIWARE security enablers: Keyrock for Identity Management, Wilma as a PEP Proxy, and Authzforce for policy enforcement.
Custom Dashboard Integrations
Building real-time GIS control maps and analytical dashboards in React and Grafana that query context brokers directly with zero caching lag.
