INSTALLER HANDBOOK

WiFi Installer Handbook

A deployment guide that treats WiFi as an RF design and validation problem, not a floor-area calculator.

Requirements before AP count

Identify users, device types, applications and performance requirements.
Obtain an accurate floor plan and understand construction materials.
Identify existing WLAN problems and known interference sources.
Decide what must be measured during validation.

RF planning

Channel width affects channel reuse.
AP placement should be designed around coverage, capacity and interference, not floor area alone.
Large channel widths can be difficult to reuse in dense deployments.
Regulatory channel and power availability varies by country and band.

Site survey

Record AP mounting locations and heights.
Capture relevant RF conditions with appropriate survey tools.
Mark interference sources and coverage concerns on the plan.
Validate the installed design after deployment.

Wired dependency

Every AP also consumes switch capacity, cabling and usually PoE.
Verify switch-port capability and PoE requirements.
Plan uplink capacity based on the network design rather than AP marketing speed.
Document the AP-to-switch-port relationship.

Configuration record

Record SSIDs, intended VLANs and authentication design without publishing secrets.
Record channel and channel width after commissioning.
Record firmware/controller baseline where operationally useful.
Keep credentials outside general project documentation.

Validation

Validate against the project's own coverage and performance criteria.
Test roaming where mobility is a requirement.
Revisit channel use and interference after the system is live.
Do not declare RF success from AP link lights.

No fake AP calculator: floor area alone cannot determine a defensible AP count. Environment, construction, client mix, capacity, interference and the project's RF targets matter.

How to use this handbook

Values that depend on a product, project specification, test limit, local requirement or manufacturer warranty must be verified from that source. Netcomtech does not turn an example product specification into a universal installation rule.
