Wireless controls: range needs site planning

Building geometry, materials and device positions influence wireless links. A range figure in a data sheet does not automatically describe performance in a hall with metal racking or several fire compartments. Changes in stored materials can also alter conditions later.

First clarify the system architecture: which devices communicate directly, which need a gateway and which functions run locally? Terms such as wireless and mesh do not replace checks of supported standards and components. Access management, updates and configuration backups also belong in the operating plan.

A site survey and pilot area using real mounting positions help identify weak links. Handover should include manual operation, restart tests and the agreed response to communication loss. Record equipment positions so future changes to the building or its use can be assessed properly.

What to clarify for your project

• Test mounting positions and obstructions in a pilot area.
• Clarify local functions and gateway dependencies.
• Secure configuration backups and system access.

Remember: Assess wireless performance against the real building and its intended use.
