Network Design
Your network is the foundation that everything else in your business runs on — your internet, your servers, your phones, your security tools, and your cloud services. Getting the design right from the outset prevents the performance issues, security gaps, and expensive remediation work that come from networks that were never properly planned.
Technicalities brings together L3 engineers with deep expertise across hardware, software, protocols, security, and performance optimisation — giving you a holistic approach that considers all the technical dimensions of your environment, not just the obvious ones.
Network design involves decisions that have long-term consequences — topology, segmentation, hardware selection, redundancy, and security architecture. Getting multiple expert perspectives at the design stage identifies risks before they become production problems, and reduces the likelihood of design flaws or vulnerabilities that are costly to fix after the fact.
We design and document networks for businesses of all sizes — from straightforward office setups through to complex multi-site environments with high availability requirements.
Network Architecture
End-to-end network topology design — core, distribution, and access layers — structured for performance, redundancy, and future growth.
Security Architecture
Firewall placement, network segmentation, VLAN design, and access control — built into the network design from the ground up, not retrofitted later.
Wireless Network Design
Site surveys, heat mapping, and access point placement — designed for seamless coverage across your entire workspace, not just the obvious spots.
Multi-Site Connectivity
SD-WAN, MPLS, and VPN design for businesses operating across multiple locations — reliable, secure connectivity between sites and to the cloud.
Redundancy & Failover
Dual uplinks, redundant switching, and failover paths — designed so that a single point of failure doesn’t take your business offline.
Network Documentation
Full network diagrams and documentation delivered with every design engagement — so your team and ours always know exactly what’s in place and why.
A network designed properly costs less to run, performs better, and is significantly harder to compromise.
The cost of getting the design right is always less than the cost of fixing a design that was wrong.Wi-Fi Network Design
Wireless network design is more complex than it appears. The most obvious placement for an access point — the middle of a room, or wherever there’s a ceiling cavity — is frequently not the best placement for seamless connectivity as people move through a workspace. Coverage gaps, channel interference, and roaming issues are almost always the result of placement that was guessed rather than planned.
Technicalities uses leading Wi-Fi design and heat mapping software to take the guesswork out of wireless planning entirely. We model coverage across your workspace using a range of different access point models before committing to any hardware — so the design is validated before a single cable is run.
Whether you’re fitting out a single-floor office or designing wireless coverage for a large warehouse or multi-building campus, the approach is the same — survey, model, validate, then implement. We don’t guess at access point placement, and we don’t commit to a brand or model until the design has been tested in software against your actual floorplan.
Every wireless network we design follows a structured process — ensuring coverage is validated before implementation begins.
Surveys
We conduct a physical site survey of your workspace — capturing floor dimensions, wall materials, obstacle locations, and any existing wireless interference that will affect coverage and signal strength.
Wireless Mapping
Using specialist Wi-Fi design software, we map your floorplan and model access point placement — testing different positions, heights, and configurations to find the optimal layout for your environment.
Visualisation
We generate heat maps showing predicted wireless coverage, signal strength, and channel overlap across your workspace — giving you a clear visual of what coverage will look like before any hardware is purchased.
Implementation
Once the design is validated, we supply and install the access points, configure the wireless environment, and verify coverage post-installation — confirming real-world performance matches the model.
