No-obligation proposal. # Wi-Fi site survey: measure before investing in business wireless At a glance For decision-makers short on time. - 01 A Wi-Fi site survey measures real wireless coverage and shows where signal is strong, weak or absent. - 02 A predictive survey plans access points from the floor plan; an on-site survey diagnoses a live network. - 03 You receive a heat map, interference analysis and a recommended access point plan. ### In this article A **Wi-Fi site survey** is the technical measurement of wireless coverage in a space, carried out before installation or to correct an enterprise wireless network. It shows where the signal is strong, weak or non-existent, what is causing interference and how many access points are needed, and in what position. ## What a site survey measures in a business wireless network Using dedicated tools, the technician walks the space and records the strength and quality of the signal in each zone. The result is a **heat map**: a floor plan in colours showing the real coverage, without interpretation. The survey also reveals congested channels and sources of interference. ## Predictive survey or on-site survey? - **Predictive**: carried out on the floor plan, before any installation exists. It is used to plan the number and location of access points. - **On site**: real measurements in the field. It is the most rigorous method and the right one for diagnosing an existing network. ## The right moments to ask for one - **New premises** Before installing Wi-Fi, to avoid dead zones and surplus equipment. - **Recurring complaints** When coverage or speed always fail in the same places. - **Move or refurbishment** New walls change the way the signal propagates. - **Growth** More people and more devices call for a different density of access points. ## What you receive at the end - **Heat map** The real coverage of the whole area. - **Dead zones** Identified, along with areas of weak performance. - **Interference** Analysis of channels and sources of noise. - **Access point plan** Recommended number, model and position. - **Report** Clear conclusions and next steps to support the decision. ## Frequently asked questions ### Does a small office justify a site survey? Yes. It avoids buying too much or too little equipment, and correcting a poorly sized installation costs more than the diagnosis. ### Can the survey be used to plan before building work? Yes. A predictive survey, carried out on the floor plan, shows how many access points are needed and where they go, before any cable or equipment is installed. ### What document do I receive? A report with the heat map, conclusions and practical recommendations, which serves as the basis for the decision and for installing the wireless network. ## Next step: measure your Wi-Fi network DataRoad - IT Services and Consulting carries out coverage surveys and optimisation for managed enterprise networks: [Wi-Fi site survey and optimisation](https://www.dataroad-it.com/en/wifi-site-survey-greater-lisbon/).
