Network design
LAN and WAN topology, VLAN segmentation, routing and QoS. Designed on paper and signed off before a single cable is pulled.

How we design it
One uplink, one firewall, four segments that cannot see each other.
You get this drawing at handover — most companies have never been given one for their own building.

Why networks decay
Almost no network is badly designed on day one. They decay:
A department moves and someone drops in an unmanaged switch. A camera system goes in on the office VLAN because it was quicker. An access point gets added where there is a spare port rather than where the coverage gap is. Three years of that, and nobody can say with confidence what is plugged into what.
The result is a network where every problem takes a day to diagnose, because the first hour is spent working out how it is wired.
What we do about it
Read before you write
Every engagement starts with a survey: physical walk, switch port audit, traffic capture, Wi-Fi measurement. You get a picture of what is installed, which is reliably different from what people believe is installed.
Design on paper first
Topology, addressing, segmentation and QoS get decided and signed off before procurement. Changing a diagram costs nothing; changing a rack costs a weekend.
Segment properly
Production machines, cameras, guest Wi-Fi, staff and card payments each get their own segment, with rules between them. On most sites it removes more risk than anything else we could do, and it is mostly configuration, not hardware.
Measure the result
Wi-Fi coverage gets verified with a post-installation survey in the aisles where the work happens. Cable runs get tested and certified. Throughput gets proven against the numbers in the design. If it does not hit the spec, it is not finished.
Server rooms and power
A resilient network on unprotected power is not resilient. We size UPS capacity against measured load rather than nameplate ratings, plan cooling for the rack density you are building to, and put physical access control on the door.
The handover pack
The deliverables list above is not aspirational. It is what you receive, and it is what makes the difference between an estate you own and an estate that owns whoever installed it.
You receive
- As-built network diagrams: logical and physical
- Cable test certificates and labelling schedule
- Device configuration backups and an IP address plan
- Wi-Fi heat map from the post-installation survey
- Monitoring dashboard with agreed alert thresholds
Who this is for
- Plants where coverage or reliability is costing production time
- Offices that have grown by adding switches to switches
- Campuses and multi-floor buildings starting a fit-out
- Anyone whose network diagram is a whiteboard photo from 2019

About networks & infrastructure
Yes, and it is how most of our infrastructure work is done. Changes are staged, scheduled into windows you approve, and every cutover has a tested rollback prepared before we start. If a step needs downtime we tell you the window and duration in advance.
