Wireless Network Solutions
Secure, scalable Wi‑Fi for offices, retail, and distributed teams.
Designed, deployed, and managed by Zefsina.
Why Business Wi‑Fi Matters
Modern workplaces demand more than just "signal." You need fast, secure, and seamless connectivity for employees, guests, and devices.
Zefsina delivers wireless infrastructure that supports real work: video calls, cloud apps, POS systems, mobile teams, and more — with full visibility and control.
We also enable advanced capabilities like Real-Time Location Services (RTLS) — allowing you to track assets, personnel, and customer movement using your wireless infrastructure.
What Is a Wireless Site Survey?
A wireless site survey is the process of planning and validating Wi‑Fi coverage in a specific environment.
It involves measuring radio frequency (RF) conditions, identifying signal interference, and determining the ideal placement for access points.
There are three types of surveys:
- Predictive — a simulation-based approach using your building layout, wall types, and planned device density to generate a virtual heatmap of expected Wi‑Fi performance.
- On-site (active/passive) — measured with specialized tools in the real environment
- Post-deployment (validation) — to verify and optimize performance
The result: a tailored wireless design that ensures strong signal, seamless roaming, and minimal interference — even in high-density or complex spaces.
Wi‑Fi Design: One of the Most Complex Areas in Networks
Wireless is not just “plug and play.” Unlike wired networks, Wi‑Fi operates in an unbounded, unpredictable environment — affected by walls, people, interference, and even weather.
That’s why professional planning, simulation, and validation are essential to avoid signal loss, performance drops, or security gaps.
At Zefsina, we treat wireless as an engineered system — with precision, tools, and deep expertise.
