  • Data communications solutions overview for smart cities waste management
    Publication . Madureira, R. C.; Ferreira, Célia
    The current works describes the data transport networks within a smart waste management system. Existing technical solutions based on cellular networks and Internet-of-things (IoT) are described and the system’s technological limitations are discussed from the smart city perspective. A comparison is made using as relevant parameters the rate of transmission (kilobits per second), the energy consumption, the coverage area and the costs. While cellular networks have higher rates of transmission and use pre-existing telecommunication infrastructures, the monthly cost can easily reach prohibitive values and prevent the use of cellular communications in smart waste systems, such as those used in pay-as you-throw (PAYT). Solutions based on IoT networks (LoraWAN and SigFox) might partially overcome communication costs, and seem especially promising, especially considering the emerging 5G technology that is expected to trigger the widespread development of IoT solutions for smart waste.

  • Tag & sensoring solutions overview for smart cities waste management
    Publication . Madureira, R. C.; Ferreira, Célia
    This paper describes the technology behind the implementation of smart waste management systems at the starting point of collecting information about the user and the amount of produced waste. This analysis is based on new technological approaches framed by the smart city concept and often associated to the pay-as-you-throw (PAYT) conceptions. We begin with an overview of the current available technologies with examples of real applications, with a glance on the costs/benefit and system’s limitations. We conclude with suggestions for further research on technology approaches to support best practices both for municipal policies and citizen’s behavior. The results show how pertinent is the developing of reliable systems to help decision makers managing waste smartly towards a truly smart city concept.
