There is always that room where the Wi-Fi “dies”. The dead zones — dead zones or weak signal — are among the most frequent complaints in an office. The good news is that they almost always have a solution. Let's look at why they happen and how to eliminate them for good.
Why do dead zones exist
- Physical barriers: thick walls, concrete, metal and glass block the signal.
- A single point of access trying to cover too large an area.
- Poor positioning of the equipment (in a corner, inside a cupboard).
- Interference from other equipment and neighbouring networks.
- High density: many devices competing for the same spot.
The solutions, in order of effectiveness
It is not always necessary to spend a lot. The right approach is to diagnose first and act afterwards:
- Reposition the access points to central and unobstructed locations.
- Add access points to cover the problem areas.
- Optimise channels and power levels to reduce interference.
- Turn on roaming for smooth transitions between points.
The importance of conducting a site survey
The professional way to eliminate dead zones is to make a site surveymeasure the signal across the entire space, produce a heat map and identify exactly where and why the Wi-Fi fails. That is how you solve it with data, instead of guessing and buying too much equipment.
Frequently Asked Questions
Does a Wi-Fi repeater fix the problem?
Home repeaters are usually a stopgap solution: they reduce speed and create unstable connections. In a business environment, the correct solution is additional integrated and managed access points.
How do I know how many access points I need?
It depends on the area, the wall materials and the number of devices. A site survey indicates precisely how many points are needed and where to place them.
Is it possible to eliminate dead zones without building work?
Often yes, with repositioning and access points connected by existing cable or via PoE. The diagnosis will say what is possible in your space.
