IoT Solutions.

Connecting the physical world to the digital realm with secure, low-power wireless hardware.

Technical Approach.

The Internet of Things (IoT) is transforming industries by enabling real-time monitoring and control. At NSquare Bros, we build the full-stack hardware infrastructure that powers these connected ecosystems. Our expertise lies in bridging the physical and digital worlds through robust, secure, and energy-efficient wireless sensor nodes and gateways. We understand that IoT is not just about connectivity; it is about reliable data delivery in challenging environments.

We specialize in Long Range (LoRa) technology, which is ideal for industrial and agricultural applications where devices need to communicate over kilometers with minimal power consumption. We design custom LoRaWAN end-nodes that can operate for years on a single battery, transmitting critical telemetry data to private or public networks. Our designs optimize the antenna matching network to ensure maximum range and link budget, even in dense urban or obstructed environments. For the underlying hardware, we rely on our rigorous Embedded Hardware design principles.

Beyond LoRa, we have deep expertise in Wi-Fi, Bluetooth Low Energy (BLE), and Cellular IoT (NB-IoT/LTE-M). We select the right connectivity protocol based on the specific requirements of bandwidth, range, and power availability. For local connectivity, we design mesh networks that allow devices to relay data, extending coverage and improving network resilience.

Security is a cornerstone of our IoT solutions. We implement hardware-based security using secure elements and cryptographic accelerators to ensure end-to-end encryption. This protects data integrity and prevents unauthorized access to the device. We also design for secure boot and over-the-air (OTA) firmware updates, allowing you to patch vulnerabilities and deploy new features remotely. Our Firmware Development team ensures these security features are implemented correctly.

Our IoT hardware development process includes rigorous field testing. We validate radio performance in real-world conditions, ensuring that the device maintains connectivity across the expected operating range. We also optimize the data payload and transmission intervals to balance data granularity with battery life and network capacity. Once validated, we can assist with Manufacturing to scale your deployment.

Frequently Asked Questions.

Which wireless technology should I choose?

The choice depends on range, data rate, and power constraints. For long-range, low-power monitoring, LoRaWAN is excellent. For high-bandwidth local applications, Wi-Fi is suitable. For short-range, low-power interaction with smartphones, BLE is the standard. We analyze your use case to recommend the optimal protocol that balances these trade-offs.

How do you ensure data security in IoT devices?

We implement a multi-layered security approach. At the hardware level, we use secure elements to store cryptographic keys. At the firmware level, we use TLS/DTLS for secure transport and implement secure boot to prevent malicious code execution. We also follow industry standards for device provisioning and authentication to ensure only authorized devices can join the network.

Can you design battery-operated IoT devices?

Yes, low-power design is our specialty. We utilize ultra-low-power microcontrollers and optimize sleep modes to extend battery life. We also implement smart transmission strategies, sending data only when necessary or when significant changes occur. We can calculate the expected battery life based on your usage profile and select the appropriate battery chemistry.

Do you support cloud integration?

While our primary focus is hardware, we design our devices to integrate seamlessly with major cloud platforms like AWS IoT, Azure IoT Hub, and The Things Network. We ensure the data payload is formatted correctly (e.g., JSON, binary) and can assist in configuring the device-side credentials for secure cloud connectivity.
