Coverage survey (site survey)
We measure the signal in every room, note walls, metal surfaces and neighbouring networks, and produce a coverage map (heatmap). From it we decide how many access points are needed and where.
Professional Wi-Fi
Business Wi-Fi installation, based on a coverage survey
A business Wi-Fi installation starts with measurements, not with buying equipment. We place access points where they are needed, with central management, smooth roaming and a separate network for guests.

Overview
Why your business Wi-Fi does not reach everywhere
Most calls we get about business Wi-Fi installation start with the same sentence: "the signal shows full bars, but it doesn't work". The cause is rarely the internet line. Usually it is a home router at one end of the premises, repeaters that halve the speed, or access points on the same channel interfering with each other.
Professional Wi-Fi is designed around three things: how many users connect at the same time, what the walls are made of and which applications people use. An open-plan office, a hotel with thick walls and a warehouse with metal racking need completely different solutions, even with the same floor area.
We handle the whole job: coverage survey, choice and installation of access points, cabling and PoE, roaming settings, guest Wi-Fi and monitoring. For the rest of the network, meaning switches, firewall and VPN, see our network installation page.
The service
What's included
Ceiling access points
We mount professional access points on the ceiling or wall, cabled and powered over PoE. Each one is set to a channel and power level that does not disturb its neighbours.
Central management
All access points are managed from one controller, for example Ubiquiti UniFi or TP-Link Omada. Password changes, new networks and updates are done once for the whole site.
Smooth roaming
We configure the network so devices move from one access point to the next without dropping a video or phone call. This matters most in warehouses with handheld terminals and in hotels.
Guest Wi-Fi on a VLAN
Guests join a separate network that only reaches the internet. They cannot see computers, printers, tills or cameras, and their speed can be capped.
Monitoring
We can see if an access point goes offline, how many users are connected and where there is congestion. With a support contract we handle updates and changes without you having to call us.
Coverage survey
How many access points does your business need?
"How many access points for this many square metres" has no single answer. One ceiling access point can comfortably cover an open space, but a concrete wall or a metal cabinet cuts the signal sharply. User count matters even more: a meeting room with thirty laptops needs its own access point, even if the signal from the corridor reaches it.
That is why we start with a coverage survey. In small spaces we take on-site measurements with the existing equipment or a test access point. In larger spaces we work on the floor plan, note the wall materials and confirm with measurements before final placement.
The goal is a strong, clean signal at every work position, good enough for video calls and VoIP, without so many access points that they interfere with each other. After installation we measure again and hand over the coverage map.
If you are considering mesh instead of wired access points, read our guide "Mesh Wi-Fi or wired access points?" at csdynamics.gr/en/odigoi/mesh-vs-access-points/. In short: mesh helps where a cable cannot be run, but for professional Wi-Fi with many users, cabled access points consistently perform better.

Professional Wi-Fi for offices, hotels, cafés and warehouses
Every business asks something different of its Wi-Fi. These are the points we focus on in each case.
Office Wi-Fi
Stable connections for video calls, cloud apps and Wi-Fi phones. Separate networks for staff, guests and devices such as printers and meeting-room screens.
Wi-Fi for hotels
Thick walls and bathroom tiles block the signal, so access points in the corridor often fail to reach the bed. We recommend in-room wall access points, one per room or per two rooms, plus coverage at reception, the restaurant and the pool.
Wi-Fi for cafés and restaurants
Many customers in a small space, so we design for density, not just coverage. A captive portal with terms of use, a per-customer speed cap and full separation from POS terminals and tills.
Warehouse Wi-Fi
High ceilings and racks full of goods change the signal depending on how full the warehouse is. We place access points between the aisles, tune roaming for handheld terminals and check compatibility with older scanners.
Retail shops
Wi-Fi for payment terminals, tills, shelf labels and cameras, each on its own network. Optional customer Wi-Fi with a welcome page.
Outdoor areas
Weatherproof access points for courtyards, terraces, pools and car parks. Point-to-point wireless links when a second building has to be connected without digging.
Equipment
Wi-Fi 6, Wi-Fi 6E or Wi-Fi 7: which to choose
Wi-Fi 6 is now the baseline for any new business Wi-Fi installation. It handles many simultaneous devices far better than older standards, which matters in offices, cafés and event spaces.
Wi-Fi 6E adds the 6 GHz band, the lower part of which is available in Europe. It has far less interference but shorter range, and only devices that support it can use it. Wi-Fi 7 brings higher speeds and the use of several bands at once. Wi-Fi 7 access points usually need a 2.5 Gbps port and more PoE power, so Cat6 or Cat6A cabling and a suitable switch.
Our advice: Wi-Fi 6 for most spaces, Wi-Fi 6E or 7 where there are many users with new devices or where you want the network to last many years. What matters most is correct placement and configuration, not the generation of the hardware.
We mainly work with Ubiquiti UniFi and TP-Link Omada, which offer central management from a computer or phone, and with MikroTik where more flexibility is needed. If you already have equipment, we check whether it can be reused.
Send photos for an estimateSecurity
Guest Wi-Fi without risk to your network
A Wi-Fi password taped to the wall, shared by staff and customers alike, is one of the most common security gaps in small businesses.
Separate VLAN
The guest network is isolated from the internal network at switch and firewall level, not just by a different network name.
Client isolation
Guest devices cannot see each other. An infected phone cannot attack another customer.
Captive portal
A login page with terms of use, a daily code or vouchers for hotels. If you ask customers for an email address, you need a proper GDPR notice.
Speed cap
A per-device limit so one customer downloading large files does not fill the line your tills and staff depend on.
Cost
How much does a business Wi-Fi installation cost?
The cost depends mainly on the number and type of access points (indoor, wall, outdoor), whether cabling already reaches the mounting points, the PoE switch and whether a controller or software licences are needed. An office with existing cabling is a much simpler job than a hotel where new cables must be run on every floor.
The quote includes the coverage survey, equipment, installation, configuration, a final measurement and documentation. Possible extras are new cable runs, a lift for high warehouse ceilings or out-of-hours work.
We offer a free site survey in Attica. If you send us a floor plan and a few photos of the space, we can often give you a first estimate before the visit.

How a Wi-Fi installation works
Discussion and floor plan
We learn how many users connect, which devices you have, which areas have problems today and whether you need guest Wi-Fi.
Coverage survey
We measure on site or on the floor plan and set access point positions, channels and bands.
Cabling and mounting
We run cables where they are missing and fit the access points and PoE switch. In working premises we work out of hours where needed.
Configuration
We create networks for staff, guests and devices, and set roaming, power, channels and the captive portal.
Final measurement
We check the signal everywhere and adjust positions or settings where needed.
Handover and monitoring
We hand over the coverage map, passwords and controller access. If you wish, we monitor the network under a support contract.
Outcome

All your Wi-Fi on one screen, with alerts when something stops working.
FAQ
Frequently asked questions
Can't find what you're looking for? Call us or send us a message.
How many access points do I need for my office?
It depends on users, walls and layout, not just floor area. An open-plan space may be covered by one or two access points, while an office with many rooms and concrete walls needs more. A coverage survey gives the exact number and positions.
How is professional Wi-Fi different from a good router?
A router, however good, broadcasts from one point. Professional Wi-Fi uses several access points with central management, coordinated channels, roaming and separate networks for each use. It copes with many simultaneous users and can be monitored.
Mesh or cabled access points?
Cabled access points give steadier speeds because they do not share airtime to talk to each other. Mesh is useful where a cable cannot be run, for example in listed buildings. We explain the differences in detail in our guide Mesh Wi-Fi or wired access points.
Does every access point need a cable?
For the best performance, yes. The cable carries data and power over PoE, so no socket is needed on the ceiling. Where a cable is impossible, a few access points can connect wirelessly.
Is Wi-Fi 7 worth it?
It is worth it when you have many users with new devices or want the network to last many years. It does need suitable cabling and a switch with 2.5 Gbps ports and more PoE power. For many small businesses, well-placed Wi-Fi 6 is enough.
How do you set up guest Wi-Fi properly?
With a separate network on its own VLAN, isolated from the internal network at the firewall, client isolation between guest devices and a speed cap. A captive portal with terms of use or voucher codes can be added.
Why doesn't hotel Wi-Fi reach the rooms?
Usually because the access points are in the corridor and the signal has to pass through the door, a wall and the bathroom. The fix is in-room wall access points, one per room or per two rooms, connected by cable. In existing hotels the existing phone or TV conduits can often serve as a route for the new cable.
Can I have Wi-Fi in the garden or by the pool?
Yes, with weatherproof outdoor access points mounted on a wall or pole. We cable them from the indoor network and add them to the same management, so customers do not have to switch networks.
What is roaming and why should I care?
Roaming is a device moving from one access point to another as you walk around. If it is not set up properly, the phone stays stuck to a distant access point and the call drops. We configure it so the handover is fast and seamless.
Can you reuse the access points I already have?
If they are still supported by the manufacturer and receive security updates, yes. Often the problem is solved just by moving them and changing settings. If the equipment is too old, we tell you so with specific reasons.
How long does a business Wi-Fi installation take?
In an office with existing cabling, mounting and configuration usually take a day. When new cables are needed, as in hotels or warehouses, the time depends on the number of points. After the site survey we give you a schedule.
Do you monitor the Wi-Fi after installation?
Yes, if you wish, through an IT support contract. We receive alerts for offline access points, apply firmware updates and adjust settings when the space or the number of users changes.
