How to choose a WLAN wireless network?
WLAN can operate in two frequency ranges:
It is more popular than the 5 GHz band. First of all, the 2.4 GHz band is compatible with most devices – even those cheaper, not very advanced or older.
This frequency band effectively reaches many rooms. It easily overcomes physical obstacles such as walls, doors or furniture. Unfortunately, it is worth considering that the popularity of this solution is also its … disadvantage.
This may be the reason for overlapping channels. In addition, it affects the decrease in the speed of uploading and downloading data.
5 GHz waves, despite the fact that they overcome physical obstacles worse, allow the use of more channels (instead of 13, as is the case in the 2.4 GHz band, there are as many as 19 in Poland). And although not all of them can be used, they still experience less occupancy than the aforementioned 2.4 GHz band.
Thus, the overlapping of signals occurs on a much smaller scale.
In addition, users can enjoy higher Internet speeds in this case. Unfortunately, in those rooms that are located further from the router, the signal may be weaker.
WLAN wireless network – where to start?
Although a WLAN network can be built very quickly, it is worth noting to do it effectively. This allows you to minimize the risk of possible disruptions right from the start. We Begin building a WLAN network with its design.
During the design stage, we may encounter a number of technical difficulties. It can be, for example, the thickness of ceilings, the material of which partition walls are made (steel, glass), power equipment, microwave ovens. These potential sources of problems affect signal coverage or transmit power and network interference.
Good practices for start
Are you interested in a WLAN network for an office building with several or several floors and many walls? You must expect, above all, that the attenuation of walls and ceilings can significantly affect the level of the radio signal. In this case, you should select several, a dozen or even several dozen access points. Sequentially place them throughout the building – so as to cover it with the range of the wireless network in accordance with the investor’s requirements.
Practice shows that such access points should be located on every second floor in every fifth office. However, this is only theory and you should be flexible in this case. The WLAN network should be tailored to the needs of a specific group of recipients and made in accordance with the design.

Already at the stage of building a WLAN network, it is worth considering the issue of its security.
In this case, it will depend on what and for whom this network is to be used. It will look different when the network will be used by specific employees, and access to it will be even divided into individual groups of employees. Still other security considerations will guide the conference rooms, where the Internet will be made available to guests staying there. And yet other rules will apply at home and its immediate surroundings.
Logistics prevails in production and transport, here the wireless network is a key element in IT and business. The wireless WLAN network should ensure smooth and fast operation of the warehouse, WMS systems and administration here.
