A Wi-Fi coverage survey shows the real cause. No-obligation proposal. # Unstable business Wi-Fi? A coverage survey finds the cause At a glance For decision-makers short on time. - 01 When Wi-Fi fails, the contracted internet is usually fine; the internal network is the problem. - 02 Walls, glass and metal shelving change the signal in ways impossible to guess. - 03 A coverage study measures the signal on site and shows where and why it fails. - 04 With the map, the fix is usually simpler and cheaper than buying more routers. ### In this article Every video call that drops costs minutes for those on it and credibility with the client on the other end. Multiply that by a whole team and a whole year. In most companies with weak **business Wi-Fi**, the contracted internet is fine: it is the network inside the office that fails. Measuring the signal on site, in a coverage study, reveals the exact cause and almost always leads to a simpler, cheaper fix than piling up routers. ## Which signs point to an internal network problem? - **Always the same room** The video meeting breaks up in the same place, week after week. - **Dead zones** Corners of the office where the laptop picks up nothing. - **Rush hour** Around 11 a.m., with everyone working, everything slows down. - **Phone hotspots** Staff who have given up and use their own data. Recognise your company? Then the problem is indoors, and you have probably already paid for fixes that solved nothing. ## Why does increasing the contracted speed not help? Because the bottleneck is not at the building's door; it is in how the signal is distributed. Consumer routers serving dozens of users, badly placed access points, radio channels trampling over each other and building materials that absorb the signal: thick walls, glass, metal shelving. Paying for more speed on a system like that is accelerating with the handbrake on. And no engineer can guess off the top of their head how the signal behaves in a specific space. It has to be measured. ## What does a coverage study actually do? An engineer walks the premises with measuring instruments and draws the real map of the signal: where it is strong, where it weakens, where there is interference and where it disappears. That map is cross-referenced with how the space is used: where video calls happen, how many people occupy each area, which devices connect. The output is a concrete diagnosis, with problems, causes and the cost of fixing them. No guesswork, no surplus equipment. ## What happens after the diagnosis? DataRoad - IT Services and Consulting designs and installs the [business wireless network](https://www.dataroad-it.com/en/business-wifi-installation/) solution: professional access points in the right places, which rarely match the old ones, channels tuned so they do not overlap, and separate networks for staff and guests. In most offices, installation is done in a single day without stopping anyone. From then on, the network can be [monitored and managed by DataRoad](https://www.dataroad-it.com/en/managed-it-services-networks-security-cloud/), as part of our managed IT services. ## Want to know where your Wi-Fi loses signal?
