Network & Wi-Fi Engineering Standard
Design and configuration rules for the network that a smart home relies on.
The essentials
- Wired backbone for every gateway and hub
- Dedicated IoT VLAN, isolated from residential traffic
- Wi-Fi 6/6E minimum for new builds
- PoE budget calculated with 30% headroom
Purpose
Ensure every smart-home platform is delivered on a network engineered for it, not on a consumer router.
Scope
All Smart Citizens residential and light-commercial deployments.
Design principles
Principle 1
Wired first, wireless when necessary
Principle 2
Segment by trust — main, IoT, guest, cameras
Principle 3
Design for coverage, not for signal at the router
Principle 4
Plan for growth — 30% headroom on every metric
Engineering requirements
Engineering requirements
- Managed switches with VLAN support
- Cat6A backbone to every AP and gateway
- Enterprise-grade access points (Wi-Fi 6 minimum)
- Separate SSIDs mapped to VLANs by function
- UPS on the network core
Best practices
Survey
Survey: Perform predictive + on-site wireless survey
APs
APs: One AP per 80–120 sqm as a starting baseline
IoT
IoT: Every IoT device on its VLAN with inter-VLAN firewall rules
DNS
DNS: Use redundant DNS resolvers
Installation workflow
Installation workflow
How it works
1. Wireless survey
Predictive survey against floor plan, validated on site after first-fix.
2. Backbone install
Cat6A pull to every AP, gateway and PoE camera location.
Configuration & programming workflow
Configuration & programming workflow
How it works
1. VLAN plan
Apply the standard VLAN plan (main, IoT, guest, cameras, admin).
2. SSID plan
Configure one SSID per VLAN with WPA3 where supported.
3. Firewall rules
Apply inter-VLAN rules from the standard rule-set.
Commissioning steps
Commissioning steps
How it works
1. Coverage validation
Walk the site and confirm signal strength meets target in every room.
2. Failover test
Reboot the core switch and confirm services resume within target.
Validation checklist
Validation checklist
- Every AP shows expected coverage per plan
- IoT devices cannot reach main VLAN
- Guest network isolated
- UPS holds network core for the design duration
- No VLAN segmentation
- Under-sized PoE budget
- AP placement optimised for looks, not coverage
Quality assurance checklist

Live firewall rules match the standard rule-set.
Acceptance criteria
| Feature | Target | Verification method | Priority |
|---|---|---|---|
Signal strength | >= -65 dBm in occupied rooms | Post-install survey | High |
VLAN isolation | Blocked | Ping/port scan from IoT to main | High |
Core UPS runtime | >= 60 min | Load test | Medium |
Risk matrix
| Feature | Likelihood | Impact | Mitigation |
|---|---|---|---|
Flat network with IoT devices | Medium | High | VLAN plan mandatory on every install |
Consumer AP in villa environment | Low | High | Only approved enterprise APs specified |
Common mistakes & troubleshooting
Troubleshooting tips
How it works
Device drops from Wi-Fi
Confirm SSID is on the correct VLAN and DHCP scope has spare leases.
High latency to cloud
Test WAN speed; check for firewall CPU saturation.
Documentation requirements
Documentation requirements
- VLAN plan
- SSID plan
- Coverage map (pre + post)
- PoE budget spreadsheet
Maintenance timeline
Maintenance timeline
How it works
Quarterly
Refresh AP firmware; re-run coverage walk.
Annually
Full site survey; UPS battery test.
UAE / GCC considerations
Villa layouts, thick walls, and dense apartment towers in the UAE demand a per-site predictive survey. Do not size AP counts from square-metre rules alone.

Frequently asked questions
Frequently asked questions
Do you replace the developer's router?
Usually yes — most developer routers cannot host the VLAN, SSID, or PoE budget a smart home needs.
Is Wi-Fi 7 required?
No — Wi-Fi 6 is sufficient for most residential installs; Wi-Fi 6E adds value in dense multi-tower environments.
