In IoT applications, a DTU (Data Transfer Unit) serves as the critical link that gathers data from meters or sensors and forwards it to cloud platforms. The chosen communication mode significantly impacts the overall system performance and scalability. Among them, polling mode — although straightforward — brings several serious drawbacks. 1. High power consumption, not […]

LoRaWAN devices can join the network via ABP or OTAA. This article provides a technical breakdown of each approach, highlighting advantages, security trade-offs, and application scenarios. Learn how to choose the right join method for your IoT deployment and why LoRaWAN 1.1 strengthens OTAA as the preferred option.

Discover why SF5 and SF6 are excluded in LoRaWAN standard. Learn about technical reasons, hardware constraints, and their potential in private IoT networks.

While LoRaWAN is widely embraced for its long-range and low-power communication, developing a field-ready device requires far more than simply enabling data transmission. This article explores the essential capabilities and design considerations that ensure a LoRaWAN device performs reliably, consumes minimal power, and can be managed at scale over long deployment cycles.

The Change of Value (COV) algorithm is becoming a core technology in low-power IoT, particularly in LoRaWAN deployments. By uploading data only when significant changes occur, COV dramatically extends device battery life, optimizes spectrum utilization, and increases network capacity. Combined with EdgeBus architecture, COV plays a crucial role in enabling scalable, efficient, and stable IoT systems.

In the IoT (Internet of Things) field, remote maintenance and firmware upgrades (OTA updates) are critical to ensure long-term system reliability and continuous feature enhancement. However, for projects based on LoRa or LoRaWAN — which use low-power, low-bandwidth communication — conventional IP-based large firmware updates are impractical due to strict bandwidth and packet size limitations

In low-power wide-area network (LPWAN) systems, LoRaWAN has become a widely adopted communication technology due to its long-range transmission, low power consumption, and broad coverage. It is commonly used in applications such as smart metering, environmental monitoring, intelligent buildings, and coal-to-electricity conversion projects. However, as the number of devices increases, two critical issues emerge: battery
