Find out how to approach the topic of planning, designing and, finally, creating an effective WiFi network in your organisation.

WiFi in a corporate environment – what role does it play?

First, we need to draw a line between WiFi networks used in homes and solutions that operate on a daily basis in companies or large corporations. To put it simply, they are in completely different leagues. While a typical home network supports a maximum of a few devices, a wireless infrastructure for business must cope with many times that number – sometimes dozens or even hundreds.

A home network usually consists of a router. In contrast, corporate WiFi consists of elements such as professional access points, wireless controllers and management systems.

WiFi network design – what to consider?

It all starts with a meticulous and thorough analysis of business needs. At this point, you need to ask (and answer) questions about the number of users using the network, the types of applications and how they are used (e.g. video conferencing, etc.). In addition, location is also important, especially the specific characteristics of the building. Determine the area to be covered by the signal and consider the future needs of your organisation (so that the infrastructure is flexible and scalable).

Remember that reinforced walls, metal structures, and thick walls can very effectively minimise or even completely block the WiFi signal.

Choosing WiFi equipment and standards

The standard for most companies is high-bandwidth WiFi 6 (802.11ax) or possibly WiFi 6E. Try to choose solutions from reputable manufacturers and pay attention to certifications and compliance with industry standards.

Access points play an important role in this entire ecosystem. Professional routers are designed to operate 24/7 and, most importantly, to handle dozens or hundreds of connections simultaneously. Their density is more important than their power. It is definitely better to use several devices with lower power, but simply use more of them.

The final piece of the puzzle is wireless network controllers, which allow you to centrally manage all access points (including network monitoring, problem tracking and updates).

Planning, design and site survey

Start with a WiFi network audit, which will allow you to check the actual signal coverage, identify sources of possible interference, and analyse bandwidth. The result should be a detailed coverage map that will allow you to plan the optimal placement of access points and select the appropriate technological solutions.

Remember: access points should ‘overlap’ to ensure smooth switching between devices.

Network security

Effective WiFi security – although we mention it last – is actually a cornerstone. In this regard, pay attention to network segmentation, incident monitoring, and physical security of access points.

Each user should have their own login and password. Guests, on the other hand, should have different access and be completely isolated from the company network.

How to build and implement WiFi? Step by step.

After the audit, planning and design stages, it is time for implementation. Start implementing your company’s WiFi network by installing access points – necessarily in the locations designated during the site survey.

In the next stages, configure the controllers, create access for different user groups and ensure that the security policy is implemented (and adhered to!). Correct radio channel and transmission power settings are key – too high a power can cause interference, too low a power can result in poor coverage.

Tip: before putting your wireless network into regular use, test its range, bandwidth, speed, authentication, and resistance to attacks.

The entire implementation should be well documented, and IT administrators should be properly prepared and trained.

What are the costs of implementing and maintaining a company WiFi network?

The final investment amount depends on many factors, ranging from the equipment itself (access points, controllers, switches) to software (e.g. licence purchases) and design and implementation services.

Ultimately, the total cost can range from several thousand to well over £10,000. The amounts depend on the size of the company and the number of planned network users, the solutions used and plans for the future.
