Abstract: The increasing number of wireless LANs using the same spectrum allocation could induce multiple interferences and it also could force the active LANs to continuously retransmit data to solve this problem, overloading the spectrum bands as well as collapsing their own transmission capacity. This upcoming problem can be mitigated by using different techniques, being site shielding one of them. If radio systems could be safeguarded against radiation from transmitter out of the specific network, the frequency reuse is improved and, as a consequence, the number of WLANs sharing the same area may increase maintaining the required quality standards. The proposal of this paper is the use of combined barriers constructed by bushes, supported by lattice structures, in order to attenuate signals from other networks and, so that, to defend the own wireless system from outer interferences. A measurement campaign has been performed in order to test this application of vegetal elements. This campai gn was focused on determining the attenuation induced in the propagation channel by several configurations that combine six specimen of Ficus elastica and six structures made of four different materials. The wind effect on the canopies is also considered. Then, the relation between the induced attenuation and the interference from adjacent networks has been computed in terms of separation between networks. The network protection against outer unauthorised access could be also improved by means of the proposed technique. (More)
