With the SMS-SHOW displays it is possible to make information networks addressed to the citizen, such as the by now well-known InfoCOM SMS already patroned by A.N.P.C.I. (Associazione Nazionale Piccoli Comuni d'Italia: National Association of the Small Towns of Italay).In making an informative network, one should mainly consider the cost for the installation of the infrastructures for the information transport; these costs often may limit the capillarity of the network and consequently the number of users. The use of the mobile phones, as an informative instrument, proved to be a step ahead but the relative management cost (increasing in proportion to the number of users) has acted as a brake on the diffusion of the service. Therefore the idea of using the informative displays where a message is read by thousands users immediately proves to be cheaper and more functional.Furthermore, thanks to the low intrinsic cost of the system,it is possible to transport the information diversified according to the zone and to the theme,
In the realization of an informative network, one should mainly consider the costs for the installation of the infrastructures aimed at the information transport: these costs often limit the capillarity of the network and consequently the number of users. The text messages taking advantage of the normal GSM network by now fully spread on the territory, allow the SMS-SHOWS displays to quickly build uncabled informative networks and, thanks to the possibility of working through fotovoltaic cells, the installations can be also made even in the most unthinkable places.The desire to move the installation point in any moment can be satisfied in few minutes.
