Blue Tower, Brussels
One line and one provider, a 4G backup and WiFi in every shared space. Fewer contracts, and a lower monthly bill.
Read the caseWe install it, keep an eye on it and pick up the phone, for one fixed monthly amount that can run through the building’s service charges. You get one number to call, and your tenants get WiFi and screens that work.
Lobby
Lobby screens people look at
Lobby screens and synced video walls that show the right thing without anyone touching them, from the tenant directory to a marketing suite that sells the floors above.
Meeting rooms
Room booking and a screen at every door
Tenants book a room on the building’s own booking page in a few clicks, and the screen beside the door shows how long it stays free and what comes next.
Tenant floors
One number for every tenant question
Tenants get our number for anything connected. Their questions reach people who know the building, and the facility manager stops being the helpdesk.
Move-in day
Online on move-in day, even when their own IT is not ready yet
A tenant moves in and is online the same morning on the building’s line, before their own contract or IT is in place. Their own line can follow whenever it is ready.
Cabling
Risers, patch panels and every floor in between
Risers, patch panels, floor boxes and the odd cable nobody can trace. We do the cabling work ourselves, so the network is not waiting on a third party.
IoT
Internet for LoRa gateways, remote access and SIM cards
A connection for the building’s sensors and systems: LoRa gateways, remote access for contractors and SIM cards where a cable will never reach.
WiFi floor
Guest and tenant networks
Guest and tenant networks per floor, with the right VLANs and none of the passwords on sticky notes. Built on the fibre or the provider that is already in the building.
IT floor
Monitored, patched and replaced
Switches, racks, cabling and the printer at reception, monitored, patched and replaced before anyone notices, with one number to call when something does need a hand.
Roof
Monitoring, support and a 4G backup
TurtleSonar monitors the building and tells us before a tenant does. When the line drops, the building stays online on 4G. Lifts, fire panels and screens included.
Solar panels
Live output on your screens, inverters and IoT online
The inverters get a connection and the lobby screen gets the live output, so the building’s own numbers are on the wall where visitors and tenants see them.
Coworking annex
Shared floors, shared rooms, members who come and go
Open floors with day passes and shared meeting rooms need WiFi and signage that cope with strangers and with churn. Ours do, including on our own floors.
Car park
Free spaces at the gate, sensors over 4G
Guidance screens at the gate and the ramp, and a connection for the chargers, cameras and barriers where the phone shows one bar. We watch it, so you hear about it from us first.
Outdoor mast
Terrace, plaza and car park
Coverage on the terrace, the plaza and the car park, on the same network as inside, so a badge or a guest code works at the door and at the picnic table.
Park
Benches, paths and lawns
The same network reaches the benches, the paths and the lawn, so a call taken outside does not drop.
Tram stop
Next tram, at the stop and in the lobby
Live departures for the tram, bus and train nearest the building, on the screen where people wait and in the lobby on the way out. It runs on our own mobility feed.
Property managers, landlords, asset managers and the contractors who keep their buildings running: these are some of the companies that have put their WiFi, screens or IT in our hands over the years.






























In an office building, the WiFi complaint lands with the facility manager, who did not choose the router and cannot log in to it. The provider’s helpdesk asks for a customer number nobody has. Meanwhile the lobby screen is still showing last week’s weather.
In a coworking space, forty members share one connection and one opinion about it. Every new member means a new password, and every departing one means a password that keeps working.
On an industrial site, the chargers, the gate and the cameras all need a connection where the phone shows one bar. The night they go offline, nobody is told.
That is where we come in. We are not a provider that ships a box or an IT company that bills by the hour. We run the technology in the building and answer for it. Commercial real estate, coworking or industrial sites: pick yours.
In our September 2025 customer survey, 96% of respondents said they were satisfied or very satisfied, and our NPS came in at 67. The full results are public, sample size included.

Three buildings that each needed something different.

One line and one provider, a 4G backup and WiFi in every shared space. Fewer contracts, and a lower monthly bill.
Read the case
The restaurant’s payment terminals had to be back online without waiting on the provider. We were on site within the hour with 4G, and the building now has a backup line of its own.
Read the case
WiFi across the park, indoors, outdoors and in the underground car park where phones give up, with one point of contact for the property manager.
Read the caseFour things we do the same way in every building.

We walk the building first: the risers, the technical rooms, the dead spot behind the lift shaft. That way the quote is written for your building.

Your servers and desktops stay as they are, and so does any UniFi equipment we can reset and take over. The rest of the network we replace, without a day of downtime for the tenants. Where it matters, two lines run in parallel, so the building stays online when a fibre is cut.

TurtleSonar runs in the building and tells the right people when something needs attention, usually before anyone at reception notices. You get a report every month.

One fixed monthly amount, remote support included, that can run through the service charges. When something needs doing, you call us and we take care of it.
Everything below comes as one service: the equipment, the installation, the monitoring and the people who answer the phone, for one fixed monthly amount with remote support included. It can run through the building’s service charges, so the cost is spread the way the building’s other costs already are.
WiFi from the lobby to the car park, internet lines with a backup on a separate network, and one team that deals with the providers.
More on WiFi and internetScreens in the lobby, the lifts and the shared spaces with departures, the tenant directory and building news, kept up to date by your team or by us.
More on digital signageLift phones and fire panels off the copper line, the BMS, cameras and intercoms each on a network of their own, and the IT for the building’s own team.
More on building systemsRoom booking with a screen at every door, meeting rooms that work when people walk in, and booking for the fitness room and other amenities.
