Urban Infrastructure Management System

Project Summary

To meet the client’s needs, we developed a comprehensive system to collect and manage data from distributed sensors monitoring key urban assets, integrating a web console and a hybrid mobile app for seamless access. The client required a robust solution to replace fragmented processes with a unified platform for real-time insights across devices. Using LoRaWAN technology, powered by the SX1276 LoRa module and STM32L4 MCU, we built a system capable of long-range data transmission up to 12km in urban environments. This past project highlights our expertise in delivering business-driven, multi-platform IoT solutions for smart city applications.

Solution We Delivered to the Client

We collaborated closely with the client to design and implement the Urban Infrastructure Management System through end-to-end consulting, development, and integration services. Here’s what we built for the client:

Centralized Data Architecture

We designed a scalable platform to collect data from distributed sensor nodes via LoRaWAN, aggregate it at a gateway, and transmit it to the client’s cloud server using MQTT for real-time analysis.
Hardware Integration

We developed optimized drivers for SPI and I2C interfaces, ensuring seamless communication between the STM32L4 MCU, SX1276 LoRa module, and sensors monitoring water, electricity, and traffic.
Custom LoRaWAN Protocol

We implemented a tailored LoRaWAN-based protocol for reliable, low-power data exchange between sensor nodes and the gateway.
Cloud Connectivity

We integrated MQTT to securely transmit data to the client’s cloud server, enabling real-time access to infrastructure metrics.
Web Console

We built an intuitive web-based console to visualize sensor data, allowing the client’s team to monitor and manage infrastructure from any browser.
Hybrid Mobile App

We developed a cross-platform mobile app (using React Native) for iOS and Android, enabling the client’s team to access real-time data and receive alerts on the go.

How We Engaged with the Client

We partnered with the client through a consulting, development, and integration model, enhanced by team augmentation:

Consulting: We worked with the client to define their business and operational requirements, design the system architecture, and select a tech stack to meet their smart city goals.
Development: Our team built custom drivers, the LoRaWAN protocol, MQTT integration, a responsive web console, and a hybrid mobile app tailored to the client’s needs.
Integration: We seamlessly integrated hardware, software, and multi-platform interfaces, conducting rigorous testing to ensure reliability across urban environments.
Team Augmentation: We embedded our experts within the client’s team, accelerating development, providing ongoing support, and equipping the client with the knowledge to maintain and scale the system.

This collaborative approach delivered a solution that directly addressed the client’s business needs while offering flexibility for future growth.

Conclusion

The Urban Infrastructure Management System revolutionized how the client monitored and managed critical city assets, delivering a cost-effective, scalable, and citizen-focused IoT solution with web and mobile access. Our team augmentation model ensured we worked as an extension of the client’s team, driving their success. Building on this past achievement, we’re ready to partner with the client again to create their next smart city innovation!
