In modern smart buildings, integrating outdoor sensors or remote IoT devices into centralized building control systems is a common challenge. The key lies in understanding how two important technologies—BACnet and LoRaWAN—can work together. What Is BACnet and Why Does It Matter? BACnet (Building Automation and Control Networks) is a standard communication protocol widely used in […]

Summary:Balancing low power consumption and operational flexibility is a key challenge in IoT terminal design. The Sleep-Wakeup (SW) mode offers a promising solution, enabling LoRa devices to stay energy-efficient while remaining responsive to local interactions. This article explores the principles and advantages of SW mode and how Manthink has implemented this feature in its LoRa

LoRa DTUs (Data Transfer Units) play a crucial role in low-power wide-area network (LPWAN) deployments. They are widely used for smart metering, environmental monitoring, and industrial data acquisition. However, in real-world projects, one thing becomes clear:Battery-powered LoRa DTUs are extremely rare in the market.Why is that the case? The reason goes far beyond “high power

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
