The classical single-carrier cell-planning procedure is extended to multicarrier systems operating over frequency-selective channels. Extension is achieved by expressing the link outage probability in terms of the statistics of the effective signal-to-interference-plus-noise ratio (SINR). This permits evidencing the role of the number of allocated subcarriers per slot on planning. The exponential...
Planning procedures for multi-carrier wireless systems based on the SINR evaluated over one sub-carrier do not allow to account for multi-carrier transmissions features where coded bits in the same block are spread over different sub-carriers. Due to channel frequency selectivity, sub-carriers can be subjected to different propagation conditions. The decoder in the receiver can compensate for errors...
Fourth generation broadband wireless access systems based on OFDMA/OFDM techniques operate in point-to-multipoint (PMP) configuration so that conventional cellular planning methods can be used for network design. As an alternative planning method fractional frequency reuse (FFR) strategy has been recently proposed for OFDMA/OFDM cellular systems such as WiMAX. For what concerns the determination of...
The 4-th generation broadband wireless interfaces for radio access will be based on OFDMA/OFDM multiple access/multiplexing techniques. The WiMAX operating the point- to-multipoint configuration is an important example. In this paper we consider some planning issues related to the problem of the frequency reuse in cellular-like OFDMA/OFDM systems. We obtain a general expression of the SINR at the...
Wireless local area networks (WLANs) based on IEEE 802.11a standard are deployed to provide network connectivity without being tethered off of a wired network. An accurate planning of indoor radio networks and/or the setup of localization procedures based on IEEE 802.11 requires the characterization of the propagation channel. Starting from experimental data obtained in the campus area of the University...
