Abstract

Careful configuration of frequencies for WLAN access points (AP) is crucial for ensuring the optimal performance of the network. Thus, advanced tools for WLAN frequency management tasks are needed. This paper presents a practical tool for the frequency management in IEEE 802.11 WLANs. The tool minimizes the interference between APs and consequently maximizes the effective capacity of the network. It also contains a graphical user interface (GUI) showing an illustrative view of the network state in frequency domain. The tool has been designed for administrators of medium and large WLAN networks, such as used in companies, airports, and campus areas. In the presented case, the throughput of the optimized network was 60 % higher compared to the original network with random channels
