Joint optimization of access point placement and frequency assignment in WLAN

The two relevant stages in cellular network planning process arc the location selection of the transmitters and the frequency assignment. In the literature WLAN planning approach treats successively those two stages. In this article we propose a new approach where location selection and frequency assignment are tackled together during WLAN planning process. This method has two important features. Firstly we use all the available channels for frequency assignment. Secondly multiple signals are taken into account to compute the SINR. Several experimental results show the benefits of this new approach.
