A fast and reliable WiFi connection has become as essential as electricity for many of us. No matter where you are working from, home or office, a strong WiFi signal is a necessity for everything nowadays. But what happens when your WiFi starts to lag in certain parts of your house or office? It is then that a simple process of WiFi heat mapping is done by professionals to see where the WiFi is lacking. In the next sections, we explain how you can use heat mapping for optimal network coverage.

WiFi Heat Mapping – A Brief 

WiFi heat mapping is a technique used to visualize the strength and coverage of your WiFi network, similar to how weather maps show different weather patterns. Instead of indicating weather conditions, WiFi heat maps use colors to show where your network’s signal is strong (hot spots) and where it’s weak or nonexistent (cold spots). This makes it easier to spot problem areas in your home or office where the WiFi doesn’t reach well.

Creating a heat map can reveal not just which areas have poor coverage but why, whether it’s due to obstacles like walls and furniture or interference from other devices. With this information, you can make informed decisions to improve your WiFi, such as moving your router to a more central location, adjusting the layout of your space, or upgrading to better equipment like mesh networks for larger areas.

Beyond simple fixes, WiFi heat mapping is invaluable for planning. It helps anticipate the needs of expanding or changing your space, ensuring that every corner remains connected. By understanding and applying WiFi heat mapping, you can improve your network’s performance, ensuring a smoother, more reliable online experience.

Why Do You Need a WiFi Heat Map?

Creating a heat map is an essential step after a WiFi site survey to ensure your space has optimal internet coverage, offering several key benefits. First, it helps you identify dead zones—those frustrating spots where the WiFi signal is either completely absent or too weak to be of any use. By pinpointing these areas during a wireless site survey, you can make informed decisions about router placement, often moving it to a more central location to enhance coverage across the building.

Furthermore, understanding the layout of weak signals allows for the strategic adjustment of devices and routers, reducing interference and thus boosting the overall performance of your network. A WiFi heat map is invaluable for planning network expansions. This visual guide aids in determining the most effective locations for extenders or additional routers if you’re introducing more devices or simply enlarging your physical space.

How to Create a WiFi Heat Map

Creating a WiFi heat map is simpler than it sounds, and you don’t need to be a tech expert to do it. Here’s a step-by-step guide:

Choose the Right Tool: There are many apps and software options available for creating heat maps. Some popular ones include Netally Airchecker G2 and WiFi Analyzer. Choose one that suits your needs and budget.

Map Your Area: Using your chosen tool, conduct a WiFi site survey, such as your home or office. Your tool will collect WiFi signal data at various points to create the map.

Analyze the Results: Once you’ve covered the area, the tool will generate a heat map showing you the signal strength across different locations. Look for areas with weak signals or dead zones.

Make Adjustments: Based on your findings in the WiFi survey and heat map, you can now move your router or add signal boosters in areas where the coverage is weak. In some cases, changing the WiFi channel on your router can also help reduce interference and improve signal strength.

Tips for Maximizing WiFi Coverage

Here are some tips to use for better WiFi coverage in your workplace:

Centralize Your Router: Placing your router in a central location can help distribute the signal more evenly throughout your space. Also, try to position the router in an open area away from corners to maximize its reach.

Keep It Elevated: In a WiFi site survey, you will notice that routers tend to broadcast signals downward, so placing it on a shelf or mounting it on a wall can improve coverage. Elevation also minimizes the chances of furniture and other objects blocking the signal.

Avoid Obstacles and Interference: Keep your router away from metal objects, thick walls, and appliances that can interfere with the signal, like microwaves and cordless phones. Less number of devices operating on the same frequency can also reduce signal messiness.

Update Your Hardware: If your router is several years old, it might be time for an upgrade. Newer routers offer better range and faster speeds. Look for models that support the latest WiFi standards, like WiFi 6, for optimal performance.

Consider Mesh WiFi Systems: For larger spaces, a mesh WiFi system can provide more consistent coverage without the need for manual adjustments. Mesh systems are also scalable, allowing you to add more nodes to cover even larger areas or eliminate stubborn dead zones.
