Whether it’s your workplace, your home or even your favorite store or restaurant, you probably know the spots in each place with the strongest wifi signal and best cell reception. And, you also know the spots where calls often drop — also known as Wifi Dead Zones. Dead Zones can zap productivity and cause frustration at work, at home and even while you are dining out and shopping.
If your WiFi has dead zones, slow speeds, or inconsistent performance, the problem usually isn’t your equipment—it’s your design.
And guessing won’t fix it.
A WiFi site survey is the only reliable way to understand what’s actually happening inside your network and eliminate coverage gaps for good.
What is a Wifi Dead Zone?
A Dead Zone or Dead Spot is an area where the radio waves are obstructed or interrupted that causes devices to lose their connection to a network.
What is a Wi-Fi Site Survey?
A WiFi site survey is a professional assessment of your wireless environment that measures:
- Signal strength and coverage
- Interference sources
- Network performance
- Optimal access point placement
The result is a data-driven wireless design based on the survey.
What Causes Dead Zones?
Wireless networks use radio waves to allow devices such as laptops, phones, and tablets to stay connected to the internet or a network in a single room, large building or even several city blocks. Anything that gets in the way of those radio waves can cause a Dead Zone including:
- Materials in your walls that interrupt radio waves such as concrete, steel, and brick
- Placement of equipment, furniture or large metal cabinets
- Other wireless systems i.e. security or sound systems
- Microwaves
- Interference from a neighbor’s wireless routers
- External wireless routers configured on the same wireless channel
Signs You Need a Wi-Fi Site Survey
If you’re experiencing any of the following, you need a Wi-Fi site survey:
- Areas with no signal or weak connectivity
- Dropped connections during critical operations
- Slow speeds during peak usage
- Inconsistent performance across locations
- Frequent user complaints
These issues impact productivity, customer experience, and revenue.
How to Find, Fix and Avoid WiFi Dead Zones
How can you detect and correct dead zones? Using Predictive Site Surveys and Heatmapping is the first step.
Using Predictive Site Surveys
Predictive Site Surveys use software programs to outline network coverage areas and utilize building blueprints and other information to estimate the radio signal and establish thresholds for minimum signal requirements based on the anticipated use of each area of the building. This allows the user to combine the needed signal with specific causes of signal interruption such as building materials or large equipment.
This is best for new locations, expansions, or remodels.
Using Wi-Fi Heatmaps
Wi-Fi heatmaps utilizes a visual map of the office and/or building combined with network performance tests to determine where network signal is at acceptable levels and where the network coverage needs to be improved. As implied by the name, the warmest areas have the best coverage and the coolest areas have the worst or no coverage. Combining Predictive Site Surveys with Heatmapping is the best way to quickly and accurately identify where network access can be improved.
Once these dead zones are identified they can be eliminated in a few ways:
- Moving Wi-Fi Access Points (AP’s) to a better location to improve the strength of the signal
- Changing the channel of the AP’s to eliminate signal conflicts with neighbors
- Installing updated AP’s with newer wireless standards like Wi-Fi 6E
- Adding AP’s to cover dead zones
Creating A Wireless Dead Zone Map
Contacting a professional IT infrastructure company for help with identifying and eliminating Dead Zones is also a way to get this done quickly and painlessly. They will also help you to determine which options are the best for removing your Dead Zones. Improving the signal in your building doesn’t need to be a daunting task and employees, customers and vendors will be much happier in an environment with a reliable wireless network.
