Our proposal is to present an alternative to the rationalization of water consumption and electrical energy, that consists in the development of a system the objective of which is to better distribute the consumption of these resources throughout the day. As is known, there are consumption peaks that define the capacity of distribution networks. If consumption were better distributed, the peaks would be reduced and as a result, existing networks could be re-dimensioned and maximized, there no longer being the need for large investments in new networks, generating in this manner, a huge benefit to environmental conservation. Brazil has an enormous potential of natural resources. Despite this, serious problems related to shortages of fresh water and electrical energy, have begun to appear. With the online monitoring forecast in this project, other gains will be obtained: a reduction in physical losses (leaks, diversions, etc.) and non-physical losses (billing evasion) and the detection of critical situations, making possible prompt corrective action in the distribution systems. Currently, the Brazilian market has no available system capable of monitoring the supply networks. Our initial goal is to meet the needs of this market, and in the future, to export the technology and the developed products to other countries. The Metropolitan Area Network (MAN), the main objective of this project, will be a low velocity, wireless network using Spread Spectrum techniques and code division multiple access (CDMA). (AU)
