Manufacturing IT

How Should Manufacturers Design Their Networks?

Segmentation, warehouse Wi-Fi, fiber between buildings, IDF placement and redundancy — the design decisions that determine whether a plant network holds up.

Reviewed 2026-08-01 by the Machina IT engineering team.

The short answer

A manufacturing network should segment office traffic, production equipment, scanners, voice and cameras into separate VLANs with firewall policy between them; use fiber between buildings and closets; place IDFs so copper runs stay in spec; validate Wi-Fi at device height with racks loaded; and include redundant internet if any production process depends on cloud systems.

01

Design order that avoids rework

  • Map the physical process and where devices live
  • Place MDF and IDFs based on distance limits, not convenience
  • Run fiber between closets and buildings
  • Define VLANs by function and write inter-VLAN policy
  • Design Wi-Fi along aisles for handheld radios
  • Plan redundancy for internet and core switching
  • Specify labeling and documentation standards up front
  • Validate with loaded racks before signing off
02

Legacy equipment is a segmentation question

Machines running unsupported operating systems can rarely be patched or replaced on your schedule. Isolating them, restricting their traffic and controlling vendor access is the practical control.

Common mistakes

What goes wrong most often.

  • Surveying Wi-Fi in an empty warehouse
  • One flat VLAN across office and production
  • Consumer access points in industrial environments
  • No documentation, so the next change is archaeology

Common questions

Straight answers, no sales theater.

How many access points does a warehouse need?

It depends on aisle layout, rack height and material, not square footage. Coverage is validated with the devices that will use it.

Do we need industrial switches?

In areas with heat, dust or vibration, yes. Office-grade equipment in a plant closet is a recurring failure source.
