From “three-way race” to “one retreat, one hold, one advance” — Sigfox has restructured after bankruptcy, NB-IoT leans heavily on the Chinese market, and LoRaWAN runs away with the private-network segment overseas. The 2026 LPWAN story is not about displacement; it is a marathon between three business models. 1. The Short Version If you only […]

A Number That Keeps Changing “How many devices can your gateway handle?” This is the first question asked at every LoRaWAN solution meeting and the first cell filled in every procurement manager’s spreadsheet. The answer is not in any product datasheet, because the same gateway in a real deployment may serve 700 devices — or

Introduction: Why do water meters, streetlights, and gateways look different on the same network? Open the datasheet of any LoRaWAN device and you will find a line item: Device Class. Water meters say Class A. Smart streetlights might be Class B. Relay cabinets and gateways are Class C. These letters are not marketing labels. They

Before a LoRaWAN device can send or receive any data, it must complete a process called activation — the step where the device obtains its network address and session keys. The activation method you choose affects security, deployment complexity, and day-to-day operations. The LoRaWAN specification defines two activation methods: OTAA (Over-The-Air Activation) and ABP (Activation

The first three articles covered GD6’s product overview, hardware design, and open-source code usage. This article addresses what field engineers care about most: taking a GD6 from the box to a live deployment. We walk through three mainstream network server integration paths — ThinkLink platform, ChirpStack, and TTN (The Things Network) — along with network

The first article introduced the GD6 open-source LoRaWAN gateway as a product. This one opens up the hardware — the reasoning behind each key component choice, and the engineering trade-offs involved. The GD6’s hardware is not exotic: an ESP32-S3 as the main controller, a Semtech SX1301 or SX1302 as the LoRa concentrator, plus Ethernet, Wi-Fi,

ManThink has officially released the GD6 (GD61x series), an open-source indoor LoRaWAN gateway. The gateway is built around an ESP32-S3 MCU with an optional Semtech SX1301 or SX1302 concentrator, integrating Ethernet, Wi-Fi, and optional 4G multi-link backhaul. It covers major LoRaWAN regional bands worldwide — including CN470, EU868, AS923, and US915 — supports the full

Millions of industrial devices — PLCs, energy meters, VFDs, sensors, thermostats — communicate over RS-485 buses every day. Getting that data into a cloud platform is the prerequisite for any digital transformation initiative. But RS-485 has no native networking capability. The market offers three approaches: Approach Representative Form Core Mechanism Wired Serial-to-Ethernet RS-485 to TCP/IP

Industrial IoT is not short on data—PLCs, energy meters, sensors, and VFDs already speak RS-485. What they lack is a reliable, low-power, long-range wireless bridge to the cloud. KC25x LoRaWAN DIN-Rail RS-485 Data Concentrator is built exactly for that. Ultra-Compact, Fits Anywhere Measuring just 69.0 × 25.0 × 25.0 mm, KC25x snaps onto standard DIN rails

Covering 29+ verified field devices across metering, industrial sensing & control, building & environment, and smart agriculture. Search by name, model, or protocol — every device comes with complete integration documentation. Why a “Device Catalog”? In IoT projects, the hardest part isn’t the technology itself — it’s figuring out “can I connect this device?” In
