“…Consequently, parameters, such as distance of user from BS or user distribution, will be general parameters, and will have similar impact in all performed simulations. Our test consists of a gradual increase in number of users inside the selected test environment; the added users will be randomly and uniformly distributed over the area, using the "IndoorHotspotUE" placer defined within the ituM2135 scenarios of the OpenWNS [2]. The same placer is used in all simulations.…”

In this paper, we analyze the voice communication over Long Term Evolution (LTE) network which is transmitted using a voice over internet protocol (VoIP), as in LTE the core network is purely packet switched, designed for high data throughput. Similarly to legacy circuit-switched network, serving the largest number of users performing simultaneous VoIP calls, and ensuring their satisfaction will be the main objective for LTE operators willing to introduce voice over LTE service. To simulate the impact of scheduling strategies in the VoIP capacity, we use the Open Wireless Network Simulator (OpenWNS). With the obtained results, we show the VoIP capacity bottleneck. We also recommend the best strategies to improve the VoIP capacity.

With license-exempt usage, huge bandwidth and very low power consumption Ultra Wideband (UWB) technology is an attractive candidate for high-rate Wireless Personal Area Networks (WPANs). However, restricted power emission limits the maximal coverage range to a few meters. Especially for dense indoor UWB systems, wireless multi-hop communication extends the transmission range easily and cost-effectively. WiMedia, world's first commercial UWB standard, is adapted to indoor environments, where collisions are expected often due to hidden devices. This paper evaluates WiMedia for wireless mesh networks by simulation and proposes a combination of the two channel access protocols, on the one hand to limit frame delay and on the other hand to gain system capacity.

“…Therefore, the following studies only include the first tier of interfering cells. This assumption has been validated with our system level simulator [9] and from Figure 4 it can be seen that the second tier of interferers only has limited impact on the SINR. Thirdly, the number of permutable RAPs is reduced, i.e.…”

Abstract-Multihop and multipoint transmissions are two of the main features towards an increased spectral efficiency for the LTE-Advanced mobile radio system. Fixed wireless relays with in-band backhauling are considered as a multihop technique in LTE-Advanced. Relays improve cell capacity and cell edge user performance depending on the deployment. In this paper, at first, results for the peak spectral efficiency of LTE-Advanced are presented and secondly, an analytical model to calculate the cell spectral efficiency of relay enhanced cell deployments in the context of the IMT-Advanced evaluation is presented. The developed model is applied to the LTE-Advanced system comparing different relay deployments with different frequency reuse schemes.
