「英中对照」Kerlink 推出 Wirnet iEdge 室内 LoRaWAN 边缘网关，直连楼宇自控系统

Retrofitting legacy commercial and industrial facilities with comprehensive sensor networks presents severe cabling, integration, and data processing bottlenecks. Kerlink addresses these operational challenges with the introduction of its Wirnet iEdge series, an indoor LoRaWAN edge gateway designed to link wireless environmental and operational sensors directly into building management systems (BMS) and industrial automation networks.

Edge-Computing Architecture and Automation Protocol Translation
Commercial building operations and industrial facilities require continuous real-time monitoring across heating, ventilation, and air conditioning (HVAC) loops, space occupancy tracking, indoor air quality metrics, and predictive equipment maintenance. Historically, incorporating low-power wide-area network (LPWAN) wireless sensors required routing telemetry to external cloud environments before forwarding commands back to local field-level controllers, introducing latency, recurring backhaul expenses, and external cybersecurity risks.

The Wirnet iEdge platform circumvents cloud routing dependencies by embedding application processing capacity directly at the physical network edge. Driven by an industrial-grade ARM Cortex-A35 processor running the KEROS v7 operating system, the gateway hosts local software routines to perform on-site data filtering, threshold analysis, and bidirectional protocol translation. The platform supports native mapping of LoRaWAN telemetry into standard operational technology (OT) field protocols, including BACnet over Ethernet, Modbus, and MQTT. This protocol translation enables building controllers, programmable logic controllers (PLCs), Java Application Control Engine (JACE) units, and the Niagara Framework to ingest wireless sensor points identically to physical wired inputs.

Hardware Design, Power Management, and Industrial Enclosures
Industrial electrical cabinets require space-efficient, low-power components engineered to operate reliably in continuous environments. The Wirnet iEdge is packaged in an IP20-rated enclosure configured specifically for standard DIN-rail mounting inside mechanical rooms and electrical distribution panels. The gateway incorporates an eight-channel LoRaWAN radio interface supported by an embedded LoRa Network Server (LNS) capable of managing over 1,000 active sensor nodes.

Power distribution flexibility is provided through Power over Ethernet (PoE) support alongside a wide direct current input range of 9 to 36 volts DC. Operating power consumption remains under 1.8 watts under standard operational loads, limiting internal heat generation within enclosed switchboards. Upstream communication to supervisory networks is established via integrated wired Ethernet or optional 4G/5G cellular modems. Compliance testing encompasses CE, FCC/IC, PTCRB, Bluetooth SIG certifications, and adherence to Radio Equipment Directive (RED) cybersecurity mandates.

Kerlink presented the Wirnet iEdge and Wirnet iEdge+ hardware at the Intelligent Building Systems (IBS) exhibition held from 14 to 15 October 2026 at Paris Expo Porte de Versailles, demonstrating protocol bridge integration to building infrastructure professionals.

Additional Context:
This section details technical specifications and competitive benchmarking not included in the original product announcement.

Indoor LoRaWAN edge gateways represent an established hardware class targeting commercial real estate decarbonisation, accelerated by European regulatory frameworks such as the Energy Performance of Buildings Directive (EPBD) and the European Energy Efficiency Directive, which require comprehensive building automation and control systems (BACS) in non-residential properties.

In this market segment, the Wirnet iEdge directly competes with established industrial LoRaWAN building automation gateways, notably the MultiTech Conduit AP and the Milesight UG65. The MultiTech Conduit AP features an ARM9 processor running mLinux or AEP, offering 8-channel LoRaWAN processing and wired Ethernet or LTE backhaul; however, its compute architecture is tailored primarily toward packet forwarding rather than containerized edge orchestration. The Milesight UG65 features an IP65 enclosure, an NXP 64-bit quad-core ARM Cortex-A53 processor, and embedded BACnet and Modbus protocol conversion, though its power consumption is higher at approximately 4.2 watts compared to the sub-1.8-watt footprint of the Wirnet iEdge.

Another benchmark in building automation environments is the Option CloudGate series, which utilizes modular expansion cards for BACnet and LoRaWAN connectivity. While modular gateways provide interface versatility, they require multi-board assembly and separate configuration environments. Kerlink's integration of an onboard LNS, hardware-level RED cybersecurity compliance, and direct DIN-rail packaging provides an integrated single-enclosure design engineered specifically for electrical contractor workflows in existing building retrofits.
