At a glance For decision-makers short on time. - 01 There is no fixed number of access points per square metre. - 02 Walls, user density, type of use and layout weigh as much as floor area. - 03 Coverage means there is signal; capacity means it can carry the load. - 04 Only a site survey defines how many access points to install and where. ### In this article Too many access points cost money and interfere with one another. Too few leave the meeting room without signal on the day of the client presentation. "**How many access points do I need?** " is the right question to ask before investing in business Wi-Fi. The serious answer is not a figure from a table: it is a measurement taken in your own space. ## What determines the number? - **Square metres** They matter, but the relationship is not proportional. - **Construction** Reinforced concrete, solid brick and metal structures cut range drastically. - **People and devices** A small, crowded area may need more access points than a large, empty one. - **Usage** Video conferencing and video consume far more than email and browsing. - **Floor plan** An open-plan office is easy; a corridor of closed offices is not. ## Why is the square-metre rule misleading? Because it measures only one thing. "One access point every so many metres" ignores walls and occupancy. Picture a 20 m² room with twenty people on Teams: it needs as much capacity as an almost empty floor. There are two separate requirements. **Coverage** means the signal gets there. **Capacity** means the signal can carry everyone in the room. A business wireless network has to deliver both. ## How do you arrive at the right number? By measuring. A site survey walks the space and records area, materials, interference and real occupancy. The output is a plan: how many access points, which model, in which position, on which channel. It is the only way to avoid both costly mistakes: too much equipment, which cannibalises itself, and too little, which creates dead zones. ## Is there an estimate to start with? A very rough one. In a recently built office, allow one access point per group of rooms or zones, with reinforcement in dense areas such as meeting rooms and busy open-plan spaces. It is useful for a budget ballpark. The number to install comes from the survey. ## FAQ: sizing your Wi-Fi ### Does "one access point per 100 m²" work? Not as a buying rule. At most it serves as an initial estimate, because it ignores walls and occupancy, which often decide everything. ### Do more access points mean better Wi-Fi? No. Excess, poorly configured equipment interferes with itself and lowers performance. You gain with the right number, well placed and on optimised channels. ### Who can give me the exact number? A site survey of your premises, which delivers a plan with the quantity, model and position of every access point. ## Why run the study with DataRoad? - **More than 138 sites and 1321 Ubiquiti devices** Under management. - **Wi-Fi 6 and Wi-Fi 7** Installed and managed by the same team. - **11 years** **232 clients** and Top 5% PME according to scoring.pt. ## Find out how many access points your business needs We measure, design and install: [business wireless networks for companies](https://www.dataroad-it.com/en/business-wifi-lisbon-managed-unifi-wifi-7/).
