In a LoRaWAN architecture, the gateway forms the core link between end devices and the Network Server (NS). Its capability to receive, decode, and forward uplink frames is primarily determined by its RF front-end and the baseband processing architecture. Modern LoRaWAN gateways commonly adopt the Semtech SX1302 chipset, which significantly enhances concurrent reception and multi-channel

Over the air firmware update is a core requirement for large scale IoT deployments especially when LoRaWAN devices are distributed in remote and inaccessible environments Since LoRaWAN provides low data rate strict payload limitation and downlink constraints FUOTA becomes a technical challenge This article explains the engineering difficulties behind LoRaWAN FUOTA and presents Manthink’s mature

In large-scale IoT deployments, many devices operate in locations where physical maintenance is nearly impossible. Firmware Update Over the Air (FUOTA) becomes indispensable for long-term device stability, especially for LoRaWAN devices operating on low bandwidth and limited payload size. This article explains the technical principles behind FUOTA, analyzes LoRaWAN-specific challenges, and introduces Manthink’s engineering-grade upgrade

1. Introduction LoRaWAN is widely adopted as an LPWAN technology due to long-range communication, low power consumption and cost-effective deployment. The Network Server (NS) is a critical component within the LoRaWAN architecture: it handles device activation, message routing, encryption/decryption, network management and operator-level controls. Selecting the appropriate NS has direct implications for reliability, scalability, operational

LoRaWAN, maintained by the LoRa Alliance, is a low-power wide-area networking protocol built on the LoRa physical layer. It enables long-range, low-power, and large-scale IoT connectivity, ideal for smart city, industrial, and agricultural applications. 1. Protocol Layers Physical Layer: Uses Chirp Spread Spectrum modulation over sub-GHz bands (433/868/915 MHz), enabling long-range and high sensitivity.MAC Layer:

In the modern IoT landscape, battery-powered temperature and humidity sensors are valued for their wire-free deployment, long endurance, and easy maintenance. Yet the challenge remains — how can such devices maintain real-time data transmission under strict power constraints? 1. Typical Applications Cold Chain and Warehousing Temperature and humidity play a crucial role in preserving food
