As LoRaWAN adoption continues to grow, differences in application layer protocols among sensor vendors have become a major challenge for system integration. While LoRaWAN standardizes the physical and MAC layers, application layer formats are left to vendors, resulting in protocol fragmentation across projects. 1. Differences in LoRaWAN Sensor Application Layer Protocols Although LoRaWAN defines standardized […]

As LoRaWAN is increasingly deployed in smart cities and industrial IoT applications, remote gateway maintenance has become a critical part of system architecture. Compared with port-forwarding tools such as NPS and FRP, VPN-based solutions provide stronger security, better scalability, and higher reliability for enterprise-grade LoRaWAN networks. 1. Network Architecture: Virtual LAN vs Port Forwarding NPS

1. Why Legacy Devices Are Difficult to Integrate into IoT Systems Industrial sites still rely heavily on RS485 meters, pulse counters and proprietary-protocol instruments. These devices usually suffer from: LoRaWAN provides long-range, low-power and cable-free connectivity, making it ideal for upgrading legacy devices. A practical solution, however, requires edge logic and a lightweight cloud platform.

As LoRaWAN deployments expand across smart cities, industrial IoT, smart buildings, utilities, and agriculture, enterprise users increasingly require secure, stable, and manageable network architectures. The LoRaWAN gateway, typically deployed outdoors or at industrial sites, is the core connectivity node of the entire network. Its long-term remote accessibility directly affects the system’s reliability and operational efficiency.

EdgeBus is a low power event driven virtual machine framework designed by Manthink for IoT edge devices operating on resource constrained MCUs. It provides a unified mechanism for data acquisition, protocol parsing, data encapsulation, uplink transmission and firmware upgrade over LPWAN networks such as LoRaWAN. EdgeBus solves essential system challenges including version management, remote FUOTA,

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
