Industrial Ethernet and PoE Selection: Standards, Isolation and Common Pitfalls
If every camera, wireless access point, electronic label and door reader on an industrial site needed its own power run, installation cost and failure points would m…
Industrial Network Redundancy: Multiple Ports, Link Backup and Failover
Downtime is expensive on an industrial site, and networking is the most failure-prone part of the chain. The goal of redundancy is not “no failures” but “a failure t…
Adding a 4G/5G Module over Mini PCIe: Engineering Essentials
Attaching a 4G/5G module to an industrial router or edge gateway looks like a matter of inserting a card. In practice, half the engineering problems come from power…
OpenWrt or ImmortalWrt? Mainline, Forks and Flashing Risk
In industrial router or software router projects, the firmware platform often matters more to the outcome than the hardware specification. OpenWrt and ImmortalWrt fr…
Upgrading to a 2.5G Network: When It Pays Off and How to Do It Cheaply
Gigabit networking was standard a decade ago but increasingly looks like a bottleneck. When NAS traffic, backups and media transfers all share one gigabit link, the…
Deploying the EDGE-RT28 Industrial Router Board: 3 LAN + 1 WAN, Wi-Fi 6 and ImmortalWrt
The dividing line between an industrial router and a consumer one is not the number of antennas. It comes down to three things: whether you can flash your own firmwa…
