Choosing the right multi-WAN technology is essential for reliable industrial networking. This guide explains the differences between WAN failover, load balancing, and bonding, covering session continuity, health checks, NAT, static IP considerations, and real-world deployment scenarios. It also compares the best applications for each approach and shows how Wavetel's industrial 5G routers—including the WR575, WR578, and WR677-D.

Remote PLC and HMI access is essential for modern industrial automation. This article explains how industrial cellular routers enable secure remote maintenance through VPN, firewall policies, NAT configuration, and reliable cellular connectivity. Learn best practices for connecting PLCs, HMIs, and industrial devices without exposing automation systems directly to the internet.

Can a low-resource LTE router with only 16 MB of flash and 64 MB of RAM reliably support OpenWrt and WireGuard? This article explores the hardware limitations of entry-level routers, including flash storage, memory, CPU performance, VPN encryption, and long-term stability. It also provides practical deployment advice, testing recommendations, and common failure scenarios. Finally, it compares the Wavetel IoT WR143 and WR255 industrial routers as reliable alternatives for indu

Choosing the right power interface is a critical but often overlooked aspect of industrial router deployment. From DC barrel connectors and terminal blocks to 4-pin Molex, PoE, and redundant dual-power inputs, each option offers unique advantages depending on the operating environment. This guide explains the electrical characteristics, deployment considerations, and best-use scenarios for common industrial router power interfaces.

In the Industrial Internet of Things (IIoT), a sudden power outage can lead to catastrophic data loss or critical system failures. Unlike commercial routers that immediately shut down, industrial routers equipped with supercapacitor-based protection mechanisms buy vital seconds of back-up power. This enables the execution of the "Last Gasp" mechanism—safely backing up critical operational data, closing communication session.

Transform your factory floor into a connected smart manufacturing hub. Learn how 5G industrial routers utilize secure VPNs, multi-WAN failover, and protocol conversion (Modbus/MQTT) to provide remote visibility and maintenance for both modern automated lines and legacy serial equipment. Explore the Wavetel lineup to find the ideal gateway for AI vision, remote PLC monitoring, and mission-critical production reliability.
