Wi-Fi designed with measurements, not assumptions.
S4 designs corporate Wi-Fi networks based on measurement: we study coverage and capacity according to real use and number of users, place the access points, separate employee, guest and device networks, and verify with a new measurement that the design is met.

Who it is for
4 layers, from radio to operation. Choose a profile to see which part of the system concerns you.
IT director
Stable, secure connectivity, with every user identified.
Operations director
Scanners and mobile terminals that do not drop off in the warehouse.
Co-owned building administrator
Wi-Fi in common areas kept separate from the administration network.
There is signal, but it does not work.
Almost all Wi-Fi complaints are about capacity, not coverage: a full meeting room, a floor on video calls, a warehouse where scanners drop off between shelves.
You need it if you recognize any of these signs:
- Video calls drop in meeting rooms and busy areas.
- Devices lose connection when moving around the building.
- Guests and employees browse on the same network.
- Repeaters or home routers were added to fill gaps.
- Nobody has measured real coverage after installation.
How the system is built.
Access points are chosen according to current IEEE 802.11 standards (Wi-Fi 6, 6E or 7) and the devices you already have. Authentication integrates with the corporate directory: each user signs in with their own account.
Radio
- Indoor, outdoor or industrial access points
- Directional antennas for special spaces
Transport
- Cabling and PoE switches to each point
- Point-to-point wireless links between buildings
Control
- Local or cloud controller
- Separate networks for employees, guests and devices
- 802.1X authentication and guest portal
Operation
- Monitoring of clients and interference
- Usage reports
- Periodic tuning
What is included and what is not.
Included in the service
- On-site measurement of coverage and interference
- Predictive design on floor plans and materials
- Sizing by users and applications
- Supply, cabling and installation of access points
- Configuration of networks, security and guest portal
- Post-installation verification measurement
Out of scope
- The internet link, which you contract with your carrier
- Cellular signal amplification
- End-user devices
Anything out of scope is coordinated with the right party or quoted separately, and is always stated in writing before we start.
How we do it, step by step.

DeliverableUsage and status reports
Reference regulations and standards.
These are the usual references for this type of system. The technical report of each project identifies which ones apply, depending on the use, size and location of the installation.
Regulatory reference, indicative
- IEEE 802.11
- Family of Wi-Fi standards: Wi-Fi 5, 6, 6E and 7.
- IEEE 802.1X
- Network access control by user or device.
- IEEE 802.3af/at/bt
- Power over the network cable (PoE) for access points.
- Law 1581 of 2012 and Decree 1377 of 2013 (Colombian data protection)
- A guest portal that collects personal data requires a privacy notice and authorization.
What stays in your hands.

How we apply it in your sector.
Works better alongside these services.
What people ask us most.
How many access points do I need?
It depends on the floor area, the materials and, above all, the number of users and what they do. The coverage and capacity study determines it.
Is it measured after installation?
Yes. The verification measurement is part of commissioning and is compared with the design.
What is a heat map?
A representation on the floor plan of the signal strength and quality measured at each point; it checks that the network meets the design.
Why separate the guest network?
So an outside device cannot reach company equipment or information. Each network has its own rules and bandwidth.
Does it work in warehouses?
Yes, with a specific design: metal shelving and goods change how the signal propagates, which is why it is measured on site with the warehouse in operation.
