—In this article we address the frequency management during WLAN planning. Frequency management refers to channels interference and SINR computation. We propose a new approach where location selection and frequency assignment are tackled together during WLAN planning process. Two steps characterize this approach. Firstly we use all the available channels(More)
Optimal planning of wireless networks is one of the most fundamental problems in WLAN design. This paper discusses the organisation of BSS in WLAN extended service set planning for large-scale deployment. We take advantage of a new geometric criterion to evaluate the coverage quality and apply them to WLAN planning. The obtained results show that using such(More)
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.(More)
The purpose of this paper is to evaluate the impact of frequency parameter settings while evaluating interference model in LTE (Long Term Evolution); the work is applied on a network. We develop and validate the interference model based on SINR which is used by 3GPP (3rd Group Partnership Project) to estimate the quality of signal received by UE (User(More)
—Frequency assignment is one of the main issues in radio networks planning. The multiple interferences are seldom taken into account in literature. There is not a framework with their modeling. A hypergraph modeling of the network gives a more realistic representation of this phenomenon. We generalize the T-coloring problem for graphs to hyper-graphs. We(More)
As acknowledged by the SESAR program, current ATC systems must be drastically improved to accommodate the predicted traffic growth in Europe. This study aims at assessing the performance of 4D-trajectory planning and strategic deconfliction, two of the key concepts identified to meet SESAR capacity objectives. Among the possible degrees of freedom, we focus(More)
—In this paper we present a study of mobile connectivity for vehicular network in urban environment. The considered area is a real map divided into equally sized cells, each characterized by a set of information including the type of structure in the cell, cell altitude and cell attraction for vehicles. These characteristics are taken into account in two(More)
