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

From a technical perspective, a LoRaWAN gateway can indeed be connected to a private server. Gateways function as data-forwarding devices that receive LoRa signals from end-devices and forward the data to a backend server. Therefore, with the appropriate configuration and development capabilities, it is possible to link a LoRaWAN gateway to a custom or private

In the LoRaWAN network architecture, gateways typically act as “transparent forwarders.” Their main function is to receive data packets from end devices via LoRa signals and forward them to the Network Server (NS), without processing, authenticating, or storing the data content. Therefore, most traditional LoRaWAN gateways do not have the capability to store or recall

When deploying a LoRaWAN network, the selection of antennas is a key factor affecting communication performance and device stability. In particular, for outdoor LoRaWAN gateways, it is common to see them equipped with N-type antenna connectors (N-type connector), rather than other types of antenna interfaces. Why is the N-type connector the preferred choice for outdoor
