These Are the Biggest Challenges in Wi-Fi Planning
Reliable Wi-Fi in businesses, on college campuses, or in hospitals and government offices is now taken for granted, just like electricity and running water. But while home Wi-Fi can still get by with a single router—and works reliably in most rooms, at least—wireless networking in a business is a logistical feat. The demands for capacity, coverage, and security are rising rapidly.
Without precise planning, businesses risk connection drops, slow data rates, and frustrated employees and users. But what makes planning modern Wi-Fi infrastructures so complicated?
The Biggest Challenges in Wi-Fi Planning at a Glance
High Device Density
In the past, signal coverage was the main goal. Today, it’s capacity: In modern offices, for example, each employee often brings not only a laptop but also a smartphone, a smartwatch, and perhaps a tablet. Hundreds of smartphones, laptops, and IoT devices simultaneously demand bandwidth in a confined space. A poorly planned network will collapse under such a load.
Complex Architectural Materials
Concrete, glass, and metal significantly attenuate signals and require precise 3D attenuation models. If these materials—which have varying degrees of attenuation—are not taken into account during the planning phase, unwanted “dead zones” often occur after installation.
Sources of Interference
Wi-Fi signals share the same space: microwaves, Bluetooth, radar, and neighboring Wi-Fi networks all use the same frequencies. These sources of interference block channels and reduce network throughput.
Mobile Working (Roaming)
Users move from one room to another (e.g., during VoIP calls) without the connection being interrupted. The device must switch from one access point (AP) to the next absolutely seamlessly and without any noticeable delay (roaming).
Frequency Management (Three Bands)
Coordinating the 2.4 GHz, 5 GHz, and the new 6 GHz band (Wi-Fi 6E/7) requires smart channel planning. The new 6 GHz band offers extremely high speeds but has a shorter range than the old 2.4 GHz band. Balancing these different characteristics requires mathematical precision.
Security & Segmentation
Guest networks must be strictly and securely separated from internal corporate data and IoT infrastructures.
The Solution: Don’t Guess, Measure and Plan Precisely
The days when access points were simply screwed onto the ceiling based on “gut feeling” are long gone. Today, professional planners rely on software-based simulations and on-site hardware measurements—such as the comprehensive planning tool from market leader Ekahau.
Ekahau: The All-in-One Solution for Professional Wi-Fi Planning
- Precise 3D Simulations: Walls are drawn with their exact attenuation values (in dB) to realistically calculate signal paths in advance.
- AI-Powered AP Placement: Algorithms automatically determine the optimal position and transmit power for access points (APs).
- On-Site Live Measurement (Site Survey): With the Sidekick 2, invisible sources of interference in the spectrum are immediately detected and eliminated.
With Ekahau AI Pro, the building is digitally reconstructed as a 3D model. Algorithms then calculate the perfect placement and transmit power of the access points before the first cable is even laid. A subsequent live measurement (site survey) ensures that the theory holds up in practice.
Wi-Fi Planning – We Do It for You
A high-performance, highly available corporate Wi-Fi network is therefore not a matter of chance, but the result of precise planning. Those who invest early in professional planning save themselves expensive hardware retrofits later and spare the nerves of all involved.
Leave the planning of your Wi-Fi infrastructure to real professionals: Avanis has been a long-standing partner of the market leader Ekahau and has already successfully implemented numerous Wi-Fi projects with a wide range of requirements. As network architects, we offer professional Wi-Fi planning, on-site Wi-Fi surveys, as well as Wi-Fi troubleshooting (fault analysis) as a service for your company.
Alternatively, we also offer Ekahau's hardware and software solutions for direct purchase. In the Avanis Academy, we train you in the use of the software and certify you as a Certified Site Survey Engineer.
We are happy to support you in planning your Wi-Fi network and advise you on all questions regarding Ekahau.
