WiFi & RF Guides
Understand what WiFi measurements mean, why coverage changes from place to place and why signal strength is only one part of a reliable connection.
Core WiFi & RF guides
Start with the measurement, then see how distance, frequency, materials and site layout reshape the signal before it reaches a device.
WiFi Signal Strength Explained: RSSI, dBm and Better Coverage
Learn why readings are negative, what common dBm ranges mean, how RSSI differs from dBm and why full signal bars do not always produce fast WiFi.
WiFi Signal Propagation: Buildings, Materials and Holiday Parks
See why radio energy spreads, reflects, weakens through different materials and leaves unpredictable shadows around metal-sided static caravans.

Go directly to the relevant explanation in either of the core guides.
Are RSSI and dBm the same?Understand the difference between a relative hardware indicator and an absolute unit of power.Compare RSSI and dBm →
Why is strong WiFi still slow?Interference, congestion, noise, cabling and the internet connection can all limit performance.See the other factors →
Should I use a WiFi repeater?Learn why an unmanaged repeater can make a managed holiday-park network harder to support.Read the repeater guidance →
How do individual materials affect WiFi?Follow separate high-resolution tests for plasterboard, glazing, masonry and metal caravan construction.View the material renders →
Which materials weaken WiFi?Compare timber, masonry, glass, reinforced concrete, foliage and metal caravan construction.Compare materials →
Why does caravan layout matter?See how sparse, perimeter and dense arrangements create different reflected paths and RF shadows.Compare park layouts →
Is a pole-mounted AP enough?Learn why height helps but antenna pattern, metal shells and the client’s return path still matter.Understand the full path →
What these guides are designed to do
The aim is useful information grounded in practical installation experience, without presenting a single measurement as a complete diagnosis.
Explain the measurement
Translate technical figures such as RSSI, dBm and SNR into language that relates to the experience of using the network.
Consider the whole connection
Separate local WiFi coverage from interference, network capacity, backhaul and the internet service behind it.
Offer practical next steps
Show what can be checked safely, what information is useful to report and when installation work may provide a better remedy.
