Before installing (or fixing) a wireless network, professionals don't guess — measure. This measurement is called site survey, and it's the difference between Wi-Fi that works everywhere and Wi-Fi full of surprises. We are going to explain what it is and when it makes sense to get one.
What is a site survey
A site survey is a professional Wi-Fi coverage survey of a space. Using proprietary tools, the signal strength and quality are measured in each zone, interference is identified, and a heat map that visually shows where the signal is strong, weak or nonexistent.
This includes
- Heatmap of actual coverage across the entire area.
- Identification of dead zones and of poor performance.
- Analysis of interference and of congested channels.
- Recommendation of number, model and position optimal access point placement.
- One clear report with conclusions and next steps.
When should you have a
- Before installation Wi-Fi in a new space (avoids dead spots and wastage).
- When there are problems recurring coverage or speed ones.
- Upon moving premises or remodel the office.
- As it increases the number of people or devices.
Predictive vs. on-premise
There are two types: the predictive survey, based on the floor plan of the space (useful before installation), and the on-site survey, using actual field measurements (the most accurate method). Depending on the objective, one or the other – or both – is used.
Frequently Asked Questions
Is it worth it for a small office?
Even in small spaces, a survey avoids buying too much or too little equipment and guarantees coverage where it is needed. The cost of the diagnosis pays off compared to installing it poorly and having to correct it.
Is it useful for planning before installing?
Yes. A predictive survey, carried out on the floor plan, indicates how many access points are needed and where, prior to any installation.
Do I get anything at the end?
Yes, a report with the heat map, conclusions and practical recommendations — a document that supports decision-making and installation.
