Modeling of a cost-to-benefit frequency function for the design of wideband wireless LANs

In the deployment of Wireless Local Area Networks for Wideband communicatio ns (WWLAN), a key and particularly critical role is played by the choice of the operation frequency range. In fact, different and conflicting aspects must be taken into account in order to perform an effective selection. In t his perspective, the paper proposes a model of the various features which c ontribute to the selection of the frequency range in a WWLAN, through the i ntroduction of a cost-to-benefit frequency function. The model, whose role in the design of WWLANs is also described in the paper, is adopted to explo re several situations varying the model parameters. The frequency behavior of the modeled function is investigated, in order to select the optimal WWL AN operation frequencies in the range 10 divided by 60 GHz. The achieved re sults, which are reported and commented in the paper, indicate the 60 GHz r ange as a very attractive candidate for the design and development of futur e WWLANs.
